to get more horsepower and quicker acceleration. I have been lurking and searching on the forum the past few days and have seen some things I can do. But I know some do not work with the AWD vibe. (ie. the cat-back system) What kind of increase in horsepower can I expect with these mods:1) K&N Stock Filter Replacement2) Cold Air Induction Kit3) Splitfire Spark Plugs w/Performance Plug wiresIs there anything else I can do to get an increase in HP & Accel?Also, does anyone know of a supercharger for the AWD Vibe or is it also not possible to have one?Thanks,BJL
welcome to genvibe, congrats on the new car!a CAI should help someI think the plugs in here are pretty good stock, and the engine has coil-on-plug, so I'm not sure where performance plug wires would go.Greenfire put a supercharger on his AWD, but unfortunately his engine blew. Probably related to other mods, people have put the SC on the 1ZZ engine and had no problems, and greenfire showed that the AWD tranny can handle the extra power.
