I ordered a free flowing air filter for my 2004 Corvette. It's a K&N so I knew I was buying a quality product. I installed it in minutes. My car has more responsive throttle than it use to. Shipped in two days!

Although it has been only a few days,i can see the difference in my grand am GT already.When i hit the gas it goes...right away.Acceleration is much better and the car seems to glide much easier at any speed.It is hard to say right now about fuel economy cause i am enjoying the acceleration of the car so much,seems to growl a bit also when i hammer it.I recommend this filter to anybody,no matter what car or truck,you WILL see a difference,well worth every penny!!!!
