Running J's whale ***** and J's cold air bumper duct, i noticed the car pulled better than OEM but how true is anyone's guess, lot more sound, heat soak was not as bad as everyone bangs on about as i have an air intake sensor so i can keep an eye on the intake temps but it could be better, Had the car mapped and made a respectable 190hp for a B16A, shame i don't have a before and after between the two but my next plan of action is to make an enclosed and sealed cold air box.
