Speed cost money your right. So what your saying is a k&n filter is modified car? Come on all of us do some mods on are cars, Its the hotrod in all of us. Vette owners are still comparing there new corvettes with 40 year old 427 sc cobras. I get it all the time when I drive my cobra and that apple to oranges.
What I'm trying to say, have fun with what your driving no matter what it is from VW to corvette don't get caught in the hype, of my dog badder than dog. It will bring nothing but hard feeling and speeding fines $$. Have fun at the track, drag strip or road course.
