I don't think it does...the air just speeds up as it goes through that part since behind it there is a big "reservior"

 

What are your guys opinions of the J's intakes vs. the AEM V2?

 

I say AEM simply based on the price difference and the hp gains. J's looks pretty, is probably better at helping throtle response...but its ridiculously priced

if you are rich enough that you can throw a couple hundred dollar bills into a fire...go for the J's. If you aren't, I say AEM and do a few cheap and simply hydrolock prevention measures

 

Yeah thats a good point. We installed the AEM on an S here and the it worked out really well for the guy. We put a bypass valve on it to prevent hydrolock.

 

ya...the bypass valve will basically prevent hydrolock...but it also basically elimantes the little amount of power gained. So then the only real purpose of the intake is noise and looks.

I say plug the drain valve on the hood...make an umbrella, or buy an Ebay one...and if you really want to, find the lowest point in the intake and drill a small pin hole in it so water can get out but not big enough for any real debris to get in, or try putting a small one way valve there or a push valve, with a push valve, you'd simply push it before you first drive it after its been sitting in rain when pushed in all the water falls out. IMO an umbrella and pluging the drain hole are plenty though

 

I moved up from the AEM V2 to the J's and couldn't be happier.

There is no available bypass valve for the AEM V2, at least not through AEM or anywhere else to my knowledge.

I had all the measures in place to prevent a hydrolock. I had my drain holes plugged but yet everytime it rained, the filter would get soaked and water would collect in the bottom tube. I've had three incidents where my engine bogged out as a direct result of having water in my AEM V2. Thankfully, there wasn't enough water to hydrolock but it was close. The final time this happened, I took the intake out and poured out a 1/4 cup of water from the bottom tube.

The weakness is in its design. The filter is exposed through the bumper opening, so you don't need to go through a deep flood to get it wet. It can and will get wet by just driving in rain. The end of the bottom tube angles upwards so when the filter get exposed to water, it easily collects in the tube. I called AEM about this issue and their response was... "Oh well."

The J's intake is superior in every way. The design, look and performance. At WOT with the J's, the F20C is louder and pulls harder, especially in mid-range. Plus, as an added benefit, I no longer have to check the damn weather channel to see if it might rain to decide if it is safe to drive the S2000 or not.

The AEM V2 is a piece of shit and waste of money. I know that J's is expensive but IMO worth every penny. Another good and relatively inexpensive intake is Comptech. Even PRM is better than the V2. But if you must stick to AEM, than get its original CAI with the bypass valve. It doesn't have the water/hydrolock friendly design defects that the V2 has.

Has anyone thought about drilling a small hole on the underside of the bottom tube, where it angles upward, as a drainage point?

 

Yep...I did two posts up

 

I've been very happy with my J's intake. I was fortunate enough to have my hood already precut, so I didn't have to deal with that. You will have to cut the stock grill in the front if you decide to go with the full snorkel.
