    Good fit and no trouble

    I followed the directions carefully which saved a lot of trial and error. Everything fit well with patience and persistence. Everything under the hood of a 370Z is tightly packed so I had to be diligent when squeezing the heat shields into place but it came together nicely. Bending and shaping the rubber heat shield seals takes patience but i got it right without messing it up.I had success on my first attempt and I'm not a mechanic. The turbo like whine is gone and now it has a growl instead. The car responded well to the changes with no check engine light. I can't say if it's much faster because I haven't pushed this car to the limits yet. I have been babying it. I will be driving it a little harder to train the computer to respond quickly when I punch it.

    AEM SRI - 2013 370Z

    Great intakes, indeed (relatively) easy plug and play design, suggest you purchase your own silicone hose for throttle body to SRI tube. Tuned and recieved approx 10-15Nm Torque across the dyno whilst maintaining a linear power curve. Very happy with the installed results and appearence!
