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.

Breathe new life into your BMW X3M and X4M with a premium, serviceable intake upgrade
The K&N 33-3160 is a high-performance filter element designed to fit the factory airbox on BMW F97 and F98 models. Built with multi-layer cotton media, it increases intake efficiency while maintaining outstanding engine protection. Clean it, re-oil it, refit it, and enjoy long-term savings compared to regularly replacing disposable paper elements. We use these on customer vehicles and the feedback has been consistently excellent for fit, quality and drivability.
