The Injen PF2055P is a polished, short-ram cold air intake for the 3.4L V6 in 1999-2004 Toyota 4Runner V6-3.4L and 1999-2004 Toyota Tacoma V6-3.4L, no tune required! The tube is 6061-T6 aluminum and uses Injen's patented MegaRam (MR) Technology, which the brand says delivers power gains while maintaining A/F ratios with no additional tuning. The manufacturer's dyno figures reach up to 13 hp and 10 lb-ft of torque. Owners on user forums describe modest results from intake changes on these trucks, so the case for this kit rests on its measured gains and no-tune design rather than a dramatic seat-of-the-pants difference.
Compared with a basic drop-in filter, the manufacturer says the filter is placed to limit hot under-hood air reaching the engine, and the short ram design will fit directly into even the tightest of engine bays. The filter is a fully serviceable Injen SuperNano-Web dry air filter, so you can clean and reuse it rather than buying a sealed replacement. Searches for a 1999-2004 Tacoma 3.4L V6 cold air intake, no-tune Toyota intake, or 5VZ-FE short ram kit typically lead to this configuration.
The manufacturer states that the PF2055P provides power gains while maintaining air-fuel ratios with no additional tuning.
The manufacturer lists replacement air filter part number X-1021-BB for this Injen PF kit. The filter itself is a dry SuperNano-Web design that can be serviced.
Per the manufacturer, it is built for the 1999-2004 Toyota 4Runner V6-3.4L and 1999-2004 Toyota Tacoma V6-3.4L. Confirm your model and trim against the manufacturer's fitment list before ordering.
The manufacturer says the kit includes everything required for a direct-fit installation, so you should not need to source extra brackets or tubing. Before you start, inspect the crankcase area. Owners on user forums working on 2003 5VZ-FE trucks report that the crankcase resonator chamber can complicate connecting an aftermarket intake, and the included fittings may not match that port. Check the fit of the tube and connections before fully tightening the clamps.
