The K&N 77-9039KP is a cold air intake for the 3.5L fuel-injected V6 in the Toyota Tacoma. K&N designs and builds the system in the USA, and it replaces the restrictive OEM air box with an aluminum intake tube and oversized filter. The manufacturer's estimate is an 18.81 HP gain at 5429 RPM, and each kit ships with dyno reports. Owners on user forums have questioned how much a naturally aspirated Tacoma gains from any intake, so set expectations around that. The kit's lifetime warranty and warranty-safe design are the main reasons to pay more than for a basic filter swap.
Fitment and install are the details to check before buying. The manufacturer lists this kit for 2016-2023 Tacoma models with the 3.5L V6, but published trim lists differ, so confirm your year and trim by VIN. The kit is not designed for body-lifted trucks.

Per the manufacturer's instruction sheet, disconnect the negative battery cable first, and write down radio presets or anti-theft codes beforehand. Expect to use a ratchet with extension, 10mm, 12mm and 13mm sockets, flat and Phillips screwdrivers, and 3mm and 4mm Allen keys. The steps include removing the engine cover, releasing the spring clamp on the crankcase vent hose, removing the three bolts holding the lower air filter housing, and fitting three rubber-mounted studs to the inner fender. The manufacturer warns that skipping steps or not using the supplied hardware can damage the intake tube, throttle body, or engine.
