10-Micron Stainless Steel Inline Fuel Filter

The Spool Performance SP-54-HXF10 is a high-performance inline fuel filter designed to safeguard critical fuel system components. Its primary function is to act as a final stage filter, removing fine particle impurities from the fuel before they reach the high-pressure fuel pump (HPFP) chamber or injectors, thereby preventing potential damage like leaky injectors. This fine filtration is crucial, especially when running performance-enhancing products such as the Spool Helix overdrive system, which increases fuel flow requirements. The standard OE filters can be overly restrictive and may even rupture under such demands, failing to filter effectively. This product is 100% E85 compatible, making it suitable for use with various fuel types. It is specifically designed for BMW models equipped with N54 and N55 engines, including vehicles such as the 1 M Coupe, 135i, 335i, 335is, 335xi, 535i, 535xi, 740i, 740Li, sDrive35i, sDrive35is, X6 35iX, and X6 xDrive35i. Users should verify fitment using their vehicle's selector tool. Please note that this product is not for sale or use in the state of California on any pollution-controlled vehicle, as per California Air Resources Board regulations.
