I want to get the z-tube, grounding wires, and intake

What intake do you recommend? Also how much improvement will i get?

 

none, if u HAVE to buy an intake get stillen or remove the power duct from the stock box.

 

Dont expect any real gains. Get the one that looks/sounds best to you.

 

You'll see some hp gain with a JWT popcharger or Stillen intake. These are the only two I would consider. As long as you're not sitting in traffic when it's 85 deg, you'll gain around 5whp up top with either one of them alone. I've seen many people dyno them same day, same car and it's pretty consistent. You might gain 1-2 hp with the z-tube, I really don't know. The stock G35 intake tube sucks because it has a sound baffle and really doesn't flow as well imo.
