The K&N PF-1100 is an inline high-performance fuel filter built around a high strength carbon steel housing and a high performance rolled seam that exceeds OEM pressure requirements. Its filter element uses high performance cellulose glass media that catches rust, dirt, and scale before they reach the injectors. At 4.813 in (122 mm) long and 2.219 in (56 mm) in outside diameter, it is compact enough to splice into an existing fuel line in place of a worn canister.
Choose this over a stock or budget filter when you want flow capacity and filtration matched to a performance fuel system rather than a basic replacement. The rolled-seam steel housing is meant to hold up under line pressure, and the cellulose media is built to keep flow restriction low, which matters on a modified car that asks more of its fuel pump. The filter carries a one-year limited warranty. Installation is straightforward: both ends are hose barbs, so you will need fuel-rated hose, hose clamps, and proper fuel-pressure relief before cutting the line. Look for the search terms "K&N PF-1100 inline fuel filter," "1984-1989 300ZX fuel filter upgrade," "2000-2004 Xterra inline fuel filter," and "95-97 200SX high flow fuel filter" when comparing options. Fitment details vary across sources, so confirm your model, submodel, and engine against the manufacturer's fitment lookup before ordering.
The most consistently listed applications are the 1984-1989 Nissan 300ZX and the 2000-2004 Nissan Xterra SE and XE. The 95-97 Nissan 200SX is also named in the product title, though some sources list a wider 200SX year range. Fitment details vary, so check your exact year, submodel, and engine against the manufacturer's fitment lookup before ordering.
It is an inline filter with single inlet and outlet hose barb ends. It is designed to be spliced into an existing fuel line, so it does not mount with a bracket like a canister filter.
Because the PF-1100 uses hose barb connections, the install is a line-splice job rather than a bolt-on swap. Relieve fuel system pressure before disconnecting anything, cut out the old filter, and fit fuel-rated hose and clamps to both barbs. Match the inlet and outlet to the flow direction marked on the housing, since reversing the filter will restrict flow. After installation, check every joint for leaks before starting the engine. The search did not turn up a manufacturer install sheet with specific tool or torque callouts, so verify model-specific routing and filter location against a service manual for your car.
