The K&N 57-2554 is a 57 Series FIPK cold-air intake for the 3.0L V6 in Ford Ranger and Mazda B3000 trucks, with the manufacturer listing the 2002-2003 model years. Its tube is roto-molded from polyethylene, and it uses a large oiled cotton filter. K&N's dyno chart estimates a gain of 9.38 HP at 4,848 RPM and about 10.2 lb-ft of torque. Buyers searching for a 2003 Ranger 3.0 cold air intake or a Mazda B3000 3.0L FIPK should note that this kit replaces the factory air box and intake tube rather than adding to them.
The case for this kit over stock is mainly airflow and durability. The filter is washable and reusable, and the manufacturer says it can go up to 100,000 miles between cleanings under normal highway driving, so there is no recurring paper-filter cost. A heat shield isolates the filter from the engine bay, and the polyethylene tube is designed to keep intake air temperatures lower than a metal tube would. The kit is also street legal in all 50 states and carries CARB EO number D-269-28, which matters for buyers in emissions-strict regions where a non-compliant intake can cause problems at inspection.
The manufacturer lists this kit for 2002-2003 Ford Ranger and Mazda B3000 trucks with the 3.0L V6. Details vary across sellers and some sources show a wider 2002-2004 range, so confirm the year and engine with the manufacturer before buying.
The manufacturer says the oiled cotton filter is washable and reusable and can run up to 100,000 miles before it needs service under normal highway driving. Driving conditions will affect that interval.
No. The manufacturer's installation instructions state that this kit was not designed to fit vehicles with a body lift.
The manufacturer states the kit is street legal in all 50 U.S. states and lists CARB EO number D-269-28.
The manufacturer's installation sheet for this kit calls for a flat-blade screwdriver, a ratchet with extension, a 5mm Allen wrench, 10mm and 13mm sockets, and 10mm and 5/8 wrenches. Installation time is commonly reported at around 60 to 90 minutes, and it uses the factory mounting points. Start by disconnecting the negative battery cable, then unplug the mass air sensor and the wiring harness on the intake tube. Release the air cleaner assembly from its tray grommets, then fit the heat shield, the new tube, and the silicone couplers, and reconnect the mass air sensor. Owners on user forums note that the 3.0L and 4.0L Rangers share the same stock air box, which helps when comparing instruction sheets. Check that your truck has no body lift before you start.
