Very satisfied!

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!
Great Filter!!

Just bought this for 46$ out the door. Immediately you notice a better throttle response. Sounds a little deeper/more aggressive. Not a noticeable HP/TQ gain (obviously since its a drop in filter) But definitely way better throttle response than the stock cotton filter. I am noticing maybe 2 mpg difference in fuel as well. So definitely worth the 46$ I also never have to pay to replace my air filter again because of K&N's lifetime warranty! So that cost alone will save me money in the long run! Excellent product, great price. Highly recommend it to anyone wanting a nice stock style drop in filter.
