Air Intake Kit?

Just curious...can you FEEL 8 horsepower? And what did 8 horsepower cost?

8 hp is just what EVO claims it makes. Not likely to happen for the average user. In fact, if I'm correct I believe Clubhead reported a hp and Tq drop after installing the EVO intake. One mod other than a supercharger or or turbo is unlikey to make a perceptible difference. You have to combine bolt on mods in order to really feel a gain.

Just what I thought. On these cars your best off saving your money and focusing on something other than "bolt on" go fast goodies. Either do it right and spend the big bucks (engine swap, engine teardown/rebuild) or don't do it at all. Intakes, exhausts, chips, for these cars will run you into the thousands of dollars and yield a measly 15-20 HP or like mentioned above you will LOSE power. Not to mention that nagging CEL. Very touchy, these cars!

I've heard from a reputable dyno shop that the EVO intake system is good for 3-4 HP at best. I just tried to have one installed last weekend but my mechanic lacked some screws that were supposed to be sent with the kit but were not. He did de-snorkel it in the process and the sound is much improved. Curious from those who know how much better the sound is with the kit installed than with just de-snorkeling it. Combined with a B&B sport muffler, it's starting to sound like a real sports car.

As pointed out in other threads, this is really seems to be a relatively expensive mod to just get more sound out of the motor. Given that my car was so quiet when I first got it that I sometimes thought the engine had stalled at a redlight, I'm happy to be able to capture some of that 911 style roar when I jump on the throttle.

At this point just wondering if it's worth going ahead and installing the EVO intake or just leaving it de-snorkeled as is.

Thanks for the posts. It now seems that it is not a good idea to install an air intake kit. I feel like my bipolar medication is not working properly after reading these posts. From what I gather:

1) Evo air intake might give you a gain in HP but you could possibly lose HP as well.
2) Evo air intake does seem to give a more guttural sound to the car.
3) Evo air intake is difficult to install.
4) Desnorkeling gives the guttural sound without any cost or loss of HP.

Based on this, it seems that I am back to not installing an air intake kit and thinking about desnorkeling.

Are there any issues with desnorkleing? Is there any point in desnorkleing other than having that increased sound?

I have been de-snorkeled for a year now. Through snow, sun, and rain. No problems! There has been great debate as to what this part actually does. Some say it brings in cooler outside air...but the way the airbox already is already sealed it can only get cooler outside air anyhow. Some say it is there to keep water and large debris (cigarettes) out of the intake. I never had water or debris problems but some do glue a screen over the air intake to lessen the possibility of this from happening. Search to find info. Still others (like me) say it is there to comply with noise level requirements. Removing this snorkel will only increase the engine intake sound. Heck, thats why I did it! To uncork the sound from this beautiful engine!

Another thing you may do (and I have) is to remove the foam part of the air filter. Just tear it off. This also increases sound and many people have done it without problems. Good Luck!

How have these mods effected your gas mileage? Improved, same or worsened??
