I just put on a conical intake (MAF bolt on) and i feel a major difference in the car and it's pretty good but does anyone know what the average hp/tq gain is for this stillen style intake? BTW i ordered this stuff from lightning motorsports and they're universal nissan adapter didn't fit. I made some adjustments and it works perfect now but I just thought I'd let you guys know.

 

according to stillen its supposed to give a 6hp gain. i dont think it does.
