Nismo factory intake

2011 Nismo#91

If you do every reasonable NA upgrade you'll only add a little more then 10% power on a nismo. There is not much you'll squeeze out of this engine unless you go FI. Other models see more of an improvement because of the restrictive stock cat back which nismo's don't have. Between all the decent intakes, I would say there's only a couple whp difference, so just go with the one you like for a decent manufacturer no ebay junk.
