I have a 2001 honda civic LX sedan. It is a automatic and I'm looking for parts that will increase my speed. Obviously its not going to be a racing car but I want to increase in acceleration. So far I have put a intake, exhaust and a throttle body spacer on which has defiantly helped. I don't want to buy useless parts so that's why I'm wondering if anyone has ideas for me? Thank you

adjust throttle cable. save money and feel a little better pedal stuff.
