Nismo factory intake

If the shop told you that $500 intakes won't net you a noticeable increase in performance, then they may have just been trying to save your some cash. You would have found plenty of arguments like that if you had searched this forum in the first place. In fact, it was my first response in this thread.

Some people in search of the almighty horsepower have found the G3s net the most horsepower. Others who are looking for more value will argue a smarter decision is the post-MAF tubes and and aftermarket filters because they have decent gains and are much less expensive ($150ish). The fact of the matter is you will not notice the power increase in either of these mods because it's like a 3-4% net increase on 300 hp.
