Obviously, I'm new to imports, but was just wondering if amybe there were some worthwhile mods, such as intakes or free mods, or maybe some things I could build myself for this motor.

Not looking for much, just something to add a lil pep is all. I have other vehicles if I want to go fast.

Also....NO EXHAUSTS. I am not a fan at all of ANY exhaust on ANY 4-cyl.. I want this car to remain quiet.
