Just installed a K&N Typhoon Cold Air Intake
today on my 2000 Celica GT. This was my first mod (aside from the S2000 antenna and fill-in decals, but those don't really count). A friend helped me, and it took us a couple of hours, but it really wasn't hard at all. It could have been done quicker, but we were very methodical in following K&N's very thorough, step-by-step instructions. Of all the instructions I've seen, K&N's is by far the most detailed and complete, which is part of why I bought a K&N instead of an AEM
. The kit is very complete with all the necessary hardware and mounting places for all the stock sensors and tubes that are needed.
At idle the sound isn't much different, but acceleration between 4K-6K RPMs produces a much deeper, louder sound that before. Kind of hard to say what kind of power gain it provides, but so far I'm pretty happy.
I bought it brand-new off eBay from Koller Dodge
for $125 plus $20 shipping. That's less than half the retail price and less than anything I've seen for AEM
