The K&N 77-9016KP is a 77 Series high-flow cold air intake for the 2000-2004 Toyota Tacoma and 4Runner with the L4 2.4L and 2.7L engines, per the manufacturer. It replaces the factory air filter and intake tube, and it uses a mandrel-bent aluminum intake tube paired with an oversized, conical filter. Because the filter is washable and reusable, with oiled cotton filter media, it avoids the recurring cost of disposable paper filters. The manufacturer lists an estimated gain of 5.41 HP @ 4365 RPM and 6.5 lbft of torque, and it notes the filter needs cleaning only every 100,000 miles under normal highway driving conditions. The kit is also legal for use in all 50 states, with a CARB EO number of D-269-31. Typical installation can be completed in 60 minutes or less with simple hand tools, according to the manufacturer. The kit includes five stainless steel clamps and two couplers.

Because this kit replaces the factory airbox, filter, and intake tube, the job is mainly a matter of removing the stock plumbing and fitting the aluminum tube and filter. The manufacturer's guidance puts a typical install at about an hour with basic hand tools. Use the five clamps and two couplers supplied with the kit, and check that the tube clears the engine bay and the hose connections seal before tightening everything down. Confirm the kit matches your engine (2.4L or 2.7L) and model year before you start.
