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.
