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.

Unlock consistent fueling under higher boost and ethanol blends with the Fuel-It S55 Charge Pipe Injection Kit. Designed for BMW’s S55 engine, this aftermarket auxiliary fueling upgrade adds additional injectors to the charge pipe, supplementing fuel volume and easing the load on the high-pressure fuel pump. Ideal for cars running flash tuning or JB4 back-end maps where the stock HPFP can become a bottleneck, this CPI solution helps reduce pressure drops that can lead to misfires and hesitation.
