Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Give your S58-powered BMW the reliability upgrade it deserves with this MMX performance oil filter cap replacement. This premium cap replaces the flimsy factory plastic top that is known to warp, split and seep, helping to prevent annoying oil leaks and protecting your engine on the road and on track. It is a straightforward like-for-like swap that elevates service quality and peace of mind at every oil change.
Designed for enthusiasts and daily drivers alike, the MMX unit offers a precise fit, a reassuringly solid feel when torqued down, and a clean, high-end look in the engine bay. We run this on our own cars and customer builds and the feedback has been consistently excellent for durability, fitment and finish.
