Perfect fit for my 1990 corvette and just clean it out and reuse it that is better than getting a new one all the time

1996 Corvette LT4
I feel an increase in my LT4, get a aftermarket air filter cover and you will be flying. 5-10 hp max with this.

Fits my 1990 corvette
There’s not much to say about this product. I’ve installed k@n filters for all my vehicles. They’re good filters. It fit perfectly on my 1990 corvette. They do what they say. The breathe better allowing more hp and torque. Get a tune for your car and you’ll be able to take more advantage of this product.

Break even 7.5 tanks
I followed the explicit instructions and it took about 30 minutes to install in my C4 Corvette. My gas mileage immediately went up 9.7%. At $110 per tank, I will recover the cost in 7.5 tanks of gas. Amazing!

Better sound and better mileage
I saw a 3MPG increase after installing this filter. Was using a standard paper filter before. Before the filter I would average 20-21MPG on this 40 mile stretch of flat highway, after the filter I was getting 24MPG. Average speed of 65MPH. You won't notice too much of a power difference but the throttle did feel crisper after the install.
