Nothing unless you are willing to void your warranty

Cold air intake not sure I'd that still void warranty tho

Keep all your stock parts so you can bolt them back on if it needs to be checked out by a mechanic or worse...the dealership!! Like Terry mentioned a cold air intake could give you a tiny boost in HP. An exhaust header (as long as it's street legal) can give you even more. There are even supercharger kits out there if you are feeling adventurous for like $5000!!

Thanks ColdinMA! What about performance chips? Have you had any experience using them in a Civic?

I haven't personally but they do change the air/fuel ratios to optimize the HP delivered. You would have to research the many brands that are out there and try the most proven and reputable.

Chips are a waste of money and will almost guarantee that you won't pass smog inspection. A cold air intake and performance exhaust MIGHT get you 20hp but buy parts that have dyno tests to back up their claims.
