The Injen PF2050P is a polished aluminum cold air intake built for the 1996-1998 Toyota 4Runner and Tacoma with the 3.4L V6. The manufacturer uses 6061-T6 aluminum tubing and a short ram layout that it says fits tight engine bays. The filter sits in a location meant to keep heat-soaked air out of the intake, which the manufacturer says lowers intake air temperatures. Owners searching for a 96-98 4Runner V6 cold air intake or a polished 3.4L Tacoma intake upgrade will find the tube finish and fitment match what they need. The stock airbox is built around restrictive, sound-muffling routing, so this kit trades that for a smoother, tuned path to the throttle body.
The manufacturer says the PF2050P is dyno-tested for horsepower and torque gains while keeping air/fuel ratios in check, so it does not require a tune. That matters for buyers who want a no-tune intake upgrade without paying for a reflash or a separate calibration. Its SuperNano-Web dry filter can be cleaned and reused, and the manufacturer lists X-1021-BB as the replacement filter. The aggressive intake tone under full throttle is a common reason enthusiasts choose it. Gain figures vary slightly across the manufacturer's materials, so confirm the exact numbers before purchase.
The manufacturer states that the PF2050P provides power gains while maintaining air/fuel ratios with no additional tuning.
The manufacturer lists direct fit for the 1996-1998 Toyota 4Runner V6-3.4L and the 1996-1998 Toyota Tacoma V6-3.4L. Confirm your model year and engine before ordering.
The manufacturer lists replacement air filter part number X-1021-BB for this intake, and the included SuperNano-Web filter is designed to be serviced.
The manufacturer says the kit includes everything needed for a direct-fit installation and provides installation instructions for it. Its general install guidance for intake systems notes that installation requires some mechanical skill, that the engine should be cool before you start, and that you should recheck alignment and clearance around the intake after installation. Owners on user forums who have swapped Injen intakes on other vehicles report the job typically takes under an hour with basic tools, though that figure is not confirmed for this 4Runner or Tacoma. Expect to disconnect the air box, transfer the crankcase vent line and the mass airflow sensor, and reseat the hose clamps at the throttle body. Review the instruction sheet before starting and confirm the tool list against it.
