I was looking at some Greddy Intake Manifolds at http://www.tunersports.com/product_info.php?cPath=21_24&products_id=139 Is it worth getting this for a stock civic EX, (i plan on putting other add ons, before i put this on, if i put this on) becuase it says Optimized fro maximum power from 7000 to 10000 RPM. I mean My civic redlines at 7000 RPMs. Is this the right thing for me or no?
