Default ***Official Intake Thread***

Please feel free to post you experiences and reviews/results so that I may update the information in this thread.

Note: While there is a lot of info here...I believe it is also lacking of a lot of info as well. I will be updating as often as I can.

Should be noted that all cars are different, and while one car may receive X amount of HP/TQ gains from a product...another may receive something more or even less. This is just to give those of us some insight into products currently available for the S2K, with what info we have on them so far.

INTAKES


PWJDM
This is currently the best intake on the market for the S2000. This is the lightest intake weighing in at a total of about 4lbs. The design was based of the ASM V.2 intake, however, PWJDM improved on ASMs design by increasing the size of this intakes parts compared to ASMs. This is a ram air intake which uses a scoop located in the front bumper opening to draw in and increased amount of cold air to the chambers and engine. Throttle response is greatly improved with this intake. Gains have been seen throughout the entire rpm range both in HP and in TQ. Proven to make gains upwards of 8-10WTQ throughout the rpm range, and equal amount of WHP through out the rev range as well peaking at around 12WHP up top. Basically I nice increased curve through the entire power band. At normal driving and low rpm cruising the intake sound is unnoticeable. It's as if the car is stock with only a slight whistle giving any hint to what is under the hood. However, once you go WOT, this intake comes to life. You get an instant growl unlike any other you'll hear from intakes. It's an echoing growl that screams to redline.


ASM V.2 & V.3 - Hood cutting is required to fit.
PWJDM based their intake off this design. Similar benefits will be seen with this intake in regards to throttle response and performance. This is a ram air intake which uses a scoop located in the front bumper opening to draw in an increased amount of cold air to the chambers and engine. V.2 was a two piece system. ASM redesigned it for V.3 into a four piece system. That's the only difference between the two.


ASM V.1 - Discontinued
This is the first intake system offered by ASM. This intake is similar in design to there current V.2 intake, but is shorter. It extend down into the bumper like the Mugen V.2 intake. Again it was made to hook up with the inlet of the Mugen SS bumper or ASMs earlier bumpers with the same inlet.


J's Racing - Hood cutting is required to fit.
This has been a favorite amongst S2K owners for some time. Smaller ram air design as compared to the PWJDM or ASM designs but with the same concept in mind. This is a ram air intake which uses a scoop located in the front bumper opening to draw in an increased amount of cold air to the chambers and engine. Along with the improvement in throttle response there are some notable gains in power throughout the rpm range. With this intake most noticeable gains have been seen more in the low end and mid-range with very little gains up top. Another intake that comes to life and screams at WOT.


Mugen V.2
This is the current available Mugen intake. Like the J's Racing intake this intake is also a smaller ram air system compared to others. Increased throttle response, and very minimal power gains low end and mid range, but has shown to give some increase up top. This intake is worse then the J's intake in the lower rpm, but out shines it in the higher rpm. The intakes inlet is placed behind the front bumper. While it draws in colder air being located outside of the engine bay, you will not get ram air effect unless you cut a hole in your bumper to draw in cold air into the opening of the intake system. Mugen designed it this way to work with their SS front bumper which comes with the opening. This is a very quiet system compared to the others. This incorporates the stock intake tubing, however, there are many aftermarket options now available to replace that. They will help smooth out the flow into the intake manifold.

Mugen V.1 - Discontinued
This is the first Mugen intake. It looks identical to that of Mugens current intake(V.2), but it extended down to the mouth of the OEM bumper. Like the ASM, and J's style ram air set ups.


Review & Dyno
Level 7
One of the newest intakes on the market in some time. Similar to the idea of the OEM style intake placing the filter inside a housing inside the engine bay. Looks to also draw cold air from outside the engine compartment. Dyno proven showing good gains upwards of 13whp over stock intake system. Doesn't look to bad either.


Podio Racing
This is yet another ram air system. Rectangular shaped air box with high performance air filter. It delivers high torque and quick response throughout full rev range. The box draws in cold air from the underneath the car with the supplied under panel and NACA duct. Made of carbon fiber & fiberglass. More information to come.


Gruppe-M
A beautiful intake system. Available both in carbon and carbon kevlar. Increases throttle response, and helps smooth out the feel of the car. No hard evidence as to performance benefits yet, but owners have said to feel an improvement from 4K rpm and up to red line.


Injen Sound Clip
AEM/Fujita/Injen Cold Air - Some cutting involved to fit.
Note: AEM makes a model for 06+ where the filter is located right in front of the bumper opening.
These a great intakes available at a very affordable price. Unlike the one's noted above these are tube style intakes which route the piping to place the filter outside of the engine bay behind the front bumper. Gains have been seen throughout the entire rpm range. A constant 2-4hp increase down low with around 5 hp increase up top has been reported. Similar results have been seen with peak torque numbers. Throttle response is some what improved. The chance of hydro-locking the engine is increased due to the filter placement. It's not as pretty as the more expensive intakes, but it gets the job done. These intakes are also known to give a deep growl at WOT, but can also be heard during normal driving with a slight whistle.


AEM V2 - Some cutting involved to fit.
This intake is the best option amongst tube style intakes. Similar to the regular AEM/Fujita intake systems, but has been known to give higher numbers in the higher rpm range. Some have reported almost 9hp increase at peak. The growl and deep tone of this intake is unlike any other.


Dyno Sheet - Stock AP1(3rd, 4th gear stock runs, then 4th gear run with just intake added)
K&N
This is also a tube style intake, but unlike the AEM the filter resides within the engine compartment. A special heat shield is placed around the filter to block unwanted heat being drawn into intake. This intake is one of the favored amongst S2K owners for it's performance benefits, and great sound. Like the regular AEm/Fujita intake this system also gives a healthy increase though out the entire rpm range. The tubing and heat shield are coated to insure that the system stays cool at all times. A great intake, and a very good price. Matching this intake with an AUT cooling plate is the best option to increase the amount of cold air flow directly to the filter.


Top Fuel V.1
No information available at this time. They have a new version out, and right now I am not sure whether this one is discontinued or not.


Top Fuel V.2
No information available at this time.


ARC
This is a very great looking intake system for the S2K. However, aside from the style it does not do anything in regards to performance. In some cases it may actually lose hp. The filter is exposed in the engine compartment, and gets hot air rather then cold. Another pricey intake that is only show worthy.


Comptech
In terms of performance this intake is a great buy. Another tube style intake, but with different styling. Like the K&N this intake keeps the filter placement within the engine compartment. A heat shield is placed around the filter to insure that the intake is getting cold air rather then the hot air from the engine compartment. The sound of this system is favored with most S2K owners. One of the better looking filter covers, but the plastic tubing is lacking in appeal. Similar gains have been seen in performance comparing with that of the AEM V2. More so towards the higher rpm. One thing to note is that many owners worry about the intake possible taking in water and causing hydro lock.


PRM
Possible the best sounding intake on the market! Tube style intake that incorporates the filter within it's tubing. Another intake that does not get out of the engine compartment. Intake is designed with a kind of air horn at the end to guide air into the tubing. A decent looking intake, but one that possible gets more hot air then cold. Gains are very minimal if any with this system.


CDA
No information available at this time. Looks similar to the PRM intake system.


HKS
The intake was made for RHD cars. The AC lines and the horn mount prevent LHD cars from mounting a 200mm filter. Some owners mount a 180mm filter instead. The heat shield that redirects air towards the filter needs a slight cut to accommodate the insulated AC line and that's basically it. This intake is very rare and hardly seen by most S2K owners. It's a tube style intake which places the filter at around the same location as the Comptech system. However, the design is not similar to others. The tubing is longer, and the shielding blocks out any area that may allow the intake to suck up hot air. The filter is placed in front of the fender open within the compartment to insure it has an area in which to receive cold air from. The heat shield is also designed to guide what ever air that may come in from the front bumper and direct it towards the filter. Gains upwards of 7-9hp have been seen.

Mugen Intake Upgrades


S2X Dry Carbon Intake Arm
Replaces the factory intake arm for use with the Mugen intake. Air has a smoother passage to the intake manifold. No info regarding any benefits as far as power, but it may increase response. Looks beautiful.


Goto Garage Intake Arm
Replaces the factory intake arm for use with the Mugen intake. The arm is a little smaller in diameter compared to the S2X arm, but it has the same basic concept in mind. Smoothing out the air flow for increased response. Stainless steel construction.


GT Design Titanium Intake Arm
Replaces the factory intake arm for use with the Mugen intake. Beautiful burnt titanium finish. Again this piece is a little smaller in diameter compared to the S2X piece, but has the same concept in mind. Smooth out the air flow for increased response. Although from the looks of it this system may not flow as smoothly as the others.


AFE Takeda
8hp Claimed from AFE

Stock Intake Improvements

Gutted Stock Air Box - FREE!
Many owners cut out the wall placed from the factory within the air box. Air gets direct access to the filter.


Samco Intake Arm
Replaces the factory intake arm for the stock intake system. Smoother flowing, but really this piece just looks good. Available in different color options.


K&N Air Filter
This is a drop-in replacement of the OEM filter. Probably the favorite from the replacements filters available on the market. Filter can be cleaned and used repeatedly.


Cosworth Air Filter
Drop-in replacement of the OEM filter. Supposed to have a 98% efficiency, and lowers intake resistence 10% over the OEM filter. Traps dust very well as well.


Mugen Air Filter
This is a drop-in replacement of the OEM filter. According to Mugen this reduces pressure by 50% and lowers intake resistance 12% over the OEM filter. Filter can be cleaned and used repeatedly.


Spoon Air Filter
This is a drop-in replacement of the OEM filter. No real info on this yet, but it's similar to the Mugen replacement filter. Filter can be cleaned and used repeatedly.


Spoon Snorkel
Snorkel that guides air from the front bumper opening directly into the intake box. Improves running conditions of the car, and helps eliminate bogging due to heat soak. Hood cutting may be needed to fit. J's Racing also offers this same snorkel.


J's Racing Snorkel
Identical in design to the Spoon Snorkel. Same benefits. Also available in carbon kevlar. The one pictures is designed for the J's Type-V hood. They make another version to fit with your stock hood.


PWJDM Snorkel
Same concept as with the Spoon snorkel that guides air from the front bumper opening directly into the intake box. Unlike the Spoon, this has a much larger snorkel opening which gets fitting into the bumper opening. Should be able to take in more air then the Spoon can, but should also yield the same benefits as the Spoon system.


AUT Cooling Panel
Improves the flow of air to the intake box that is received from the front bumper opening, and insures that as much of the remaining air is passed through to cool the radiator. These are available through other companies as well (J's, Backyard Special, etc.).

Hope this is helpful.

Although technically a manifold and throttle body change as opposed to an intake tube change, ITB's should be cataloged in here as well.


Jenvey Individual Throttle bodies
Although technically the manifold does "bolt-on" to the head, that's as far as bolt-on goes. A standalone is required for optimal tuning and power extraction, as well as modification to the fuel system and an injector change. Huge increases (over 40rwhp at vtec engagement) in the midrange, unparalleled throttle response, and an induction howl that can be compared to a banshee with its ass hair on fire, this is easily the great googa mooga of intake systems.

great info thanks guys. Geeky side note, reason the mugen has worse midrange then the other because of the air storage behind the filter which is used most during midrange i believe, so bigger post filter air tank better midrange in theory.

Also you can buy upgrades for the mugen such as different intake arms, not sure if they do anything besides add looks and i would imagine save weight if its a titanium or carbon fiber intake arm.

Thanks guys! I'll update it again soon with your suggestions. I had originally thought of leaving ITBs out, but your right...they should be added in none the less.
