I have a 1994 Honda Civic DX. It still has the stock 1.5 ltr engine in it, and all it has as far as performance parts is a catback exhaust and an Injen Cool Air Intake with an APC filter. I am looking for a couple of ways to make it more powerful, but I am trying to spend less than $100. Does anyone know of any little accessories I can put on there to give it a bit more power?
