The K&N 57-9014-1 is a 57 Series FIPK cold-air intake for the 2000-2001 Toyota Tundra with the 4.7L V8. It is built around a roto-molded high-density polyethylene tube and a large, washable oiled cotton filter, and it is meant to replace the factory filter and intake tube rather than sit on top of the stock airbox. Search terms it targets include 2000-2001 Tundra 4.7L cold air intake, K&N 57 Series FIPK, and reusable cotton gauze Tundra air filter.
Against a cheaper drop-in filter or a basic tube, the case for this kit rests on airflow and reuse. The manufacturer says the filter needs cleaning only about every 100,000 miles of normal highway driving, which removes the recurring cost of disposable paper elements. Power claims need care: the manufacturer promises a horsepower and torque gain, but no exact figure is confirmed on its own specification page. Owners on user forums are mixed. One 2001 4.7L owner reported more horsepower and better fuel economy, while another reported no measurable power change and mainly a different intake sound.
This is a bolt-on job that uses the factory mounting points, and the manufacturer's materials cite about an hour or less with basic hand tools such as 10mm and 14mm sockets. Disconnect the negative battery cable first, since this erases preset radio and memory settings, and some radios will ask for an anti-theft code. Use the supplied hardware exactly as directed, because the manufacturer warns that skipping steps or substituting parts can damage the intake tube, throttle body, or engine. Time estimates vary, so confirm the timeline against the manufacturer's install sheet before you start.
The manufacturer lists the 57-9014-1 for the 2000-2001 Toyota Tundra with the V8-4.7L engine. Fitment details vary across sources, so confirm your model year, cab, and engine against the manufacturer's fitment guide before ordering.
Yes. The manufacturer's install sheet says disconnecting the negative battery cable erases preset electronic memories. Some radios also require an anti-theft code after reconnecting, and the owner's manual typically lists that code.
Plan on a bolt-on installation that uses the factory mounting points. The manufacturer's materials list a ratchet with extension, 10mm and 14mm sockets, a 10mm wrench, an Allen key, flat and Phillips screwdrivers, and pliers. The main gotchas are disconnecting the negative battery first, securing the heat shield and mass air sensor with the supplied hardware, and not improvising substitute fasteners, since the manufacturer warns this can damage the tube, throttle body, or engine. Time estimates differ, so follow the manufacturer's step-by-step sheet included with the kit.
