Cut holes at the front bumper where some put ek foglights and route duct to it, that way you know you are getting extra cold airs to ur intake.

 

think whatever you like - with AEM v2 IAT reading consistently shows 10-15 degr less than with stock air box.

 

 

What does it matter if your getting engine bay temperature air when your not moving? You need the extra 5 hp when at a stand still? You dont need Max hp for stop and go traffic. The stock airbox gets cool air when the car needs it: when your carving your favorite backroad or at the track. If you are drag racing, you might want lower air temps at launch but Honda did not design this (or any other) car for drag racing.

 

The term "cold air intake" is for marketing and marketing only. 90% of the gains are due to resonance of the longer pipe, the other 10% is due to the lower IAT's. Expect 10-20* lower IAT's while cruising.

The OEM intake is a joke. The pipe is way to short to make any decent power. Even the FIPK pipe is longer.

 

What does it matter? The ignition timing is pulled as intake temperatures go up. This is one of the hottest running motors ever made, so an intake that sits up front and soaks up engine bay temps kind of sucks when you're driving around in traffic. It feels like trying to do a 2nd gear start when it gets really hot.

 

While resonance helps a little with headers, the improvement will be at specific rpm points - the reinforcing resonance frequencies. One of the reasons it works is that the resonance is tuned for each cylinder - the length of the header pipe before the collector.

With the intake, I can't see how a longer, single intake can provide any resonance boost. Resonance boost would seem to be impossible since the four intakes are combined before the benefit of resonance would be realized. What am I missing?

And as far as "heat soak" goes, the thermal capacity of the plastic intake box is so small that I can't see a significant effect once you are much past idle. Here again, can someone explain these claims.

While Honda would have had some production cost constraints, they put a lot of design thought and effort into the S2000 and it doesn't seem that anything was an afterthought. As for the aftermarket vendors, while many of them make quality products, their incentive is to convince potential buyers that they actually provide something extra, whether performance, sound, or whatever.

I'm just skeptical of the aftermarket snake oil that's out there. Recall the "super spark plugs" or "gasoline ionizers" or any number of fuel economy or performance hacks that have been sold for decades. Fortunately, most of the S2000 aftermarket stuff is not in the same class as this snake oil, but Honda has set a fairly high bar with the S2000 design.

Of course, if you pump more air into the engine, you will get more performance. I just can't imagine that a couple of holes in an air box and a couple of hoses would do very much to an already optimized design.

Just my $0.02 worth.

 

I can't argue with that logic. I also don't get some of these so called aftermarket "cold air" set-ups offering eye candy aluminum piping at the expense of discarding the minimal heat absorbing plastic intake.If there was so much to be gained in terms of performance for so little effort,the word is not out.

 

even on cruize my Scangauge shows 10-15 degr Celcius drop comparing to stock intake.

i would love if somebody knowledgeble would explain what it does to engine performance.

 

The other day I was curious about the temps of the intake box and filter after a casual drive. The box and filter were very warm especially the rear and top portions of the box closest to the engine.

Has anyone attempted anything to prevent the stock air box from getting so hot? possibly some heat deflection material covering the entire box?
