Review on 🚗 K&N Cold Air Intake Kit for Honda S2000 2000-2008, 2.0L and 2.2L L4 - High Performance, Guaranteed Horsepower Increase - 50-State Legal - Model: 57-3514 by Ben Barrington

I bought the 63 series when I first got my s2000 but it was expecting CARB and couldn't seem to pull through. I bought it because I thought I'd buy better later. This item costs money. The most noticeable part is the tone, especially when you push VTEC. The payoff isn't that big, but it's there. However, I had to smoke my car since I live in California and without the CARB sticker I couldn't even take it to the shop. I searched online and found this new version which was CARB. No taxes from Revain either and 2 days free shipping with my main account which I got and installed right away. It only takes about an hour. This is the same setup and looks as the 63 series but CARB. The sensations are the same, but the sound is much louder. But then maybe because I finally replaced my filter 5 years ago. Only cleaned once a year. A great place to start if you don't want to spend over $1000 on carbon or other JDMs.
