I was wondering if there are any minor modifications that can be made to the 2003 4 cyl that can increase performance. I have a 1998 Trans Am and a new high flow air box & air filter and exhaust system really spiced up the performance. Anythings like that on the 03 Accord 4 cyl. Haven't owned a Honda since 1982 so I'm so far behind the curve it's sad.
Thanks

 

yep you can get anything from an intake to a turbo for your car.
