## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Easy power gains
  

*by B***T on Reviewed in the United States 🇺🇸 on October 3, 2017*

I'm no mechanic and was able to fairly easily install this on my 06 g35 sedan. Make sure your torque wrench is the correct PSI readout, I believe there is inch/feet and you WILL NEED to torque it down in 3 increments or you'll have huge air leak.Once I had it installed correctly the power increase is definitely noticeable. This will give you more bang for the buck than any exhaust or CAI for cheaper.
