Got those for a 2015 370z car is stock as if new from mechanics point of view. After 6 to 8 weeks the car turned to have a huge acceleration lag and I believe the MAF’s need to be either cleaned or replaced. I would recommend to think 20 times before you jump into flushing OEM’s parts into good marketing after market ones.. Not happy with the results at all

had it for a week and i already have improved gas mileage and the engine is breathing better. keep in mind this only includes one filter so you’d have to order another one for the VQ37VHR. perfect oem fitment and amazing quality.

No real difference in induction noise on the 370Z. However as these last the lifetime of my car I will save not putting cheap over priced ones at service intervals. Plus added bonus of engine bay bling K&N stickers. =)
