I Did Some Testing of Air Filters on My Wifes C Coupe.
I Tested the ITG and The K/N.. The ITG Lost Horsepower .. And The K/N Gained 3hp (Dyno Proven)The Number Should Be greater with the car at speeds...
Also The K/N Will Pay for Itself over time as It will last Longer!
You Wont feel the gain..But all Small Gains Add Up!
