No more struggling on n54 oil filter cap!
Color: Black, Color: Black
First of all, this is a lifesaver. Getting the oil filter cap on the bmw N54 is a pain to tighten. I can not stress it enough. However this oil filter cap is most definitely the best purchase i have ever made during the oil change process. Before i bought it i damaged my oil filter cap because i didn't have the correct wrench and had to use big pliers to tighten it. Im glad i made this purchase, it’s affordable, good quality, super easy to use, grips the cap well, looks nice and clean, and works extremely well overall. This makes my life owning a N54 powered BMW much more convenient, especially as a DIY’er. I would 100% recommend this product, 5/5 stars.

MYHusband does my 2015 bmw x5 oil change usually it’s an extra charge for this piece to get this done at the mechanics So he orders it through Amazon and gets the oil changed in no time no extra charge. Works great. Fits perfectly. Amazing quality. Worth the money. Easy installation finish the job quick
