Ricky, if he has a cone filter, then Green doesn't make it.

I dynoed it several times for fun. With a stock car, no other mods, K&N got me just over zero HP, .1 at the rear wheels which is almost .13 at the crank. With my foam filter from ITG I got about 1HP at the rear wheels.
But here's the side benefit people don't talk about. With a cheaper, poorly made filter that doesn't sit in the housing right or doesn't filter quite as well, you can easily contaminate the MAF sensor. Many think it's the oil in a K&N filter, and that maybe so, I say it's just poor fit and filtering that does it. Way before it triggers the CEL, it will rob you of power and performance way beyond the .1 HP it gets you out of the box.
Happy Modding....
