To make BIG power NA you need a Big plenum. This guy was designed to maximize air for ITBs. We saw a 10HP jump with this plenum and proper ducting over normal open throttles. And that was with the hood open. Would have been even greater with the hood closed. This can work for virtually any 4 cylinder with any ITBs. I have just a few left and they will not be made again. Jump on the website to get one now!

Idk why people say you can't put a pedalbox in a s2000. I'm 6'1" and what I have done here is pretty darn good ergonomically. 🤷🏼
