The K&N 50-9039 is a NextGen cold air intake for the 3.5L V6 (2GR-FKS) in 2016-2023 Toyota Tacoma trucks. It pairs a semi-enclosed hybrid airbox, which the manufacturer says lowers intake air temperature and blocks more contaminants, with a large-diameter, CAD-designed tube that uses internal air channels to speed airflow. The filter is a red, washable, reusable oiled cotton element, so there are no recurring paper-filter purchases. Stock intake housings are restrictive by design, and this kit replaces that path with a smoother, wider inlet that feeds the throttle body more air. Owners on user forums report a sharper throttle response and a fuller intake note, while others see little change on a stock engine, so set expectations accordingly.
Shoppers comparing a K&N intake with a drop-in filter should know the difference is structural. Owners on user forums note that a drop-in filter keeps the factory airbox and does not draw cooler air the way a full intake does. This 50 Series kit is a bolt-on replacement for the factory intake tube and airbox, which makes it a better fit for buyers chasing a true cold-air setup on a 2016-2023 Tacoma 3.5L. Search terms that match this purchase include K&N NextGen Tacoma 3.5L intake, 2016-2023 Tacoma V6 cold air intake, Tacoma 2GR-FKS intake upgrade, and oiled cotton washable Tacoma air filter.
The manufacturer states that a typical installation takes around an hour and that the full system can usually be installed in under 60 minutes. Owners on user forums report that removing the factory intake took only about five minutes, but first-time installers should allow extra time for the airbox and sensor connections.
The manufacturer describes the included High-Flow filter as washable and reusable, built with oiled cotton media. Clean it according to the manufacturer's care guidance rather than replacing it on a fixed schedule.
A drop-in filter installs into the factory airbox. The manufacturer describes the NextGen airbox as semi-enclosed, designed to lower intake air temperatures and improve protection from contaminants. Owners on user forums generally consider a full intake kit like this one a more complete cold-air setup than a drop-in filter.
The manufacturer lists this intake as a direct replacement that typically takes around an hour, and owners on user forums say the factory intake comes off quickly. Before you start, disconnect the negative battery cable, unplug the mass airflow sensor, and disconnect any crankcase or EVAP vent lines attached to the factory intake. Keep the factory intake hardware and clips in case you later return to stock. Install-time estimates vary, so plan for a longer session if this is your first intake swap. Confirm the included hardware and tool requirements against the manufacturer's installation sheet before you begin.
