Cold Air Intakes Mythbusted [Naturally Aspirated]

In this episode the boys compare a Cold Air Intake system with a factory intake on the Honda S2000 to see if it makes as much power as some people have claimed...

Also something to note around Mighty Car Mods: we are normal guys and are not trained mechanics. We like to make interesting car mods and show you how we've gone about it, but we can't promise that anything we show you will work for your particular car, or that you won't harm yourself, someone else, your car or your warranty doing it. Please be safe, be responsible and unless you know what you're doing, do not fool around with very serious machinery just because you've seen us make it look so easy. Talk to a qualified mechanic if you are in any doubt.

Here I thought I would be posting original content on testing a CAI on an NA engine, only to wake up to this fantastic video. Well, two is better than none. Great watch - I found similar results on my Acura Integra (no vtec yo). There was an increase in power on the top end. 

[TheRoggan]

Biggest improvement is the NOISE!!

Love that intake sound, its also much more dynamic than the exhaust sound, very quiet at low throttle and loud at high throttle!

My cat has VTEC. At about 2-3 am (while i'm sleeping). I always hear I can only assume that is 1/4 mile passes.

3 to 5 kilowatts = 4 to 6.7 horsepower.

Pro tip for all of you looking to get a cold air intake. Buy a cheap CAI kit on ebay, you can find them for about $50. Then, measure the filter that comes with it and buy a K&N or AEM replacement filter that is the same size. Replace the filter and you're good to go, and you just got a high quality CAI for around $100.

You guys should put a cold air intake on a highly restricted, inexpensive and low performance but not utterly pathetic car and see if it makes a difference. Like a Toyota Matrix or something.

I did a K&N intake on my 05 S2K AP2 and i noticed the gains for sure. A noticeable amount of low end torque and for sure higher power in the high end of the rev range. Plus the sound is worth every penny!
 Great vid!

170hp vs 177hp.... Thats a Really Big Difference!
Cold Air-Intake for the Win!!

Love having to turn down the volume every time he talks

[davect]

It really depends on the car. Some intakes are perfect the way they are, some can be improved.

[dafiltafish]

I would say the resounding answer should be "it depends", a theme they glossed over last time around.

[drunkdogartwork]

i would love to see you guys do a cold air vs stock air box on a late 90s early 2000s car like a mercury grand marquis. this stock box is just that. a box with a flat square filter. lets see what us regular folks will get from cold air.

[Norbert.Gardonyi]

I came here to check if I should replace the air intake in my RX-8, thought it might be the same for most of the cars. THANK god you were talking SPECIFICALLY about the rx-8, right at the beggining of the video! Great help! Love ya guys!

[jimmybrite]

My buddy had a cold air intake on his rx-8 and it made more power BUT, he also had a piggyback ecu, modified exhaust and the car was professionally tuned. It sounded like a beast until he blew the engine.

[BENK]

Anyone else notice the Los Pollos Hermanos shirt he's wearing, from Breaking Bad?

[i.am.the.greatest]

colder air increases density, more density means more air in combustion chamber. add some bigger injectors for more fuel, jet and tune for e85 and you got the coldest more air fuel and higher octane, bigger bangs = more power

[JimmyMakingitwork]

Factory systems are cold air intake systems(most). All the aftermarket ones do is eliminate the noise baffling and smooth the air inlet a bit. If the factory air box is not restricted, the throttle body, cylinder heads and cam profile are the only way to increase airflow.

Short term fuel trim will correct changes almost immediately, so there is no “lean advantage.”

[ImPattMan]

Once again, they've chosen a high performance vehicle to test this, which is probably the least likely to see an increase in power from an intake mod.
