How exactly did it help? Faster throttle response? Better fuel economy? More horsepower/torque? Better sound quality? More JDM points? Makes it easier to attract the ladies? Some details would be nice because I didn't really notice any drastic changes besides the fact that my engine bay looks a little nicer with a dash of blue color, but besides that, nothing.Love this thing! Had it on my rolla for forever and i swear it helped with all the heavy driving and the mods i had on it. BTW, it looks waaay better than the Apexi one.
