check this out: I typed "honda accord tuner" into yahoo! and this came up:

check it out, a CAI, headers, and exhaust all from DC sports.
I can't vouch for their products personally (I don't even know if it's been released yet) but that article looks pretty good: "An additional 24.6 hp and 19.9 lb-ft of torque was unleashed over baseline on the final test run"
