Fitted a K&N Typhoon to the Lexus this week. Sounds nice when you blip the throttle, but pulling away for the first time after turning the key feels REALLY sluggish, car takes a little while to perk up.
I've reset the ECU, made no difference. Any suggestions before I ditch the Typhoon and go back to the standard intake?
p.s. the Typhoon is for the IS300, I figured it would work in the GS as the engines are the same, only the mounting points and shape of the standard intake differ.
