JimGnitecki said:Before anyone gets too excited about the K&N, K&N itself only claims about 4 hp gain for their Aircharger kit (that's the $400 kit, NOT the drop in air filter). If anyone is getting more than that, they should contact K&N as I'm sure K&N will want to know how you did it.
As for that throttle body spacer, save your money.
I will be glad to supply the before and after dyno charts along with the AirRaid filter number. Not sure how to post them.
The Dyno was done by Dynocomp here in Scottsdale. They are also an independent tester for AirRaid so they was amazed with the results.
