K&N Cold Air Intake Kit for 2004-2008 HONDA S2000: High Performance, Increased Horsepower (63-3514 Compatible) Review

I recently added this Performance Intake System to my car and the difference is amazing! The increase in horsepower and acceleration is noticeable and the sound of the engine is now much more aggressive. The installation was straightforward and took just a few hours. Overall, an excellent investment for any automotive enthusiast looking to improve their car's performance. The only downside is that it may void your manufacturer's warranty.

Noticeable improvement in fit and strong suction growl. Easy installation (take your time). Probably the best bang for the buck for a complete intake system for the s2000. It really cleans the engine bay area, and with the cold air duct instead of the lower intake design, I don't have to worry about puddles. I recommend pulling your computer's fuse or battery cable so the car can relearn how much air is available. Even with the stock exhaust, the car makes loud noises. My setup was on model 06.

I agree with the other review here. So far I haven't noticed a big increase in performance, but the sound quality is significantly better than with the standard box. I think it's quieter at idle but makes a raspier sound at full load, especially when VTEC is engaged it screams. Haven't noticed any rumble in the exhaust noise either. I also noticed a slight increase in gas mileage, maybe 1-2mpg. Since the S2k was built to be a near-perfect car, it takes a lot of money to increase performance, so
