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. =) ### ⭐⭐⭐⭐⭐ Tres bonne qualité *by C***N on 21 February 2026* Qualité kn impeccable ### ⭐⭐ Think 2 twice before putting those kN filters on. *by M***E on 13 January 2021* 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..
