Well last week I wrote K&N and they called me on Monday asking if they could use my redline for testing of there proto type cold air intake. This intake was show at the SEMA show this year. I said hellya!!! So on Wensday I dropped off my car and by Thursday they were done. They gave me a dyno of my cars horsepower . They also told me that with there intake there was a 10 hp gain with peeks of 20 to the front wheels . I will try to down load the dyno sheet so that all of you can see.
