07- Tundra 4.7/5.7L Perf. Air Filter

The 07-Tundra 4.7/5.7L Performance Air Filter from K&N Engineering (model 33-2387) is engineered for Toyota Tundra owners seeking genuine intake flow improvements without sacrificing engine protection. Built to replace your factory restrictive air filter, this performance upgrade addresses a critical bottleneck in the intake path—the stock filter's pleated paper design inherently limits volumetric efficiency, especially during sustained acceleration or towing operations. Whether you're running the 4.7L V8 or the later 5.7L powerplant, unrestricted airflow translates directly to improved throttle response, better power delivery, and measurable gains in fuel economy under steady-state cruising.

K&N's signature cotton-gauze media construction is the key differentiator here—the layered design provides superior flow characteristics compared to conventional paper filters while maintaining genuine particulate capture through electrostatic charge and mechanical filtration. Unlike disposable filters, this unit is cleanable and reusable for the lifetime of your truck, with K&N's proprietary red engine oil acting as a conduit for both filtration and filter longevity. The filter measures 12.3 x 1.8 x 14 inches and weighs just 2.26 lbs, making installation straightforward in the factory air box without modification. The rigid plastic frame ensures no airbox flex or bypass, and the design directly replaces OEM filters without requiring custom ducting or intake fabrication.

This filter is ideal for Tundra owners seeking a bolt-on power upgrade that demands zero tuning or custom work—whether you're running stock internals or have already invested in ignition timing adjustments and fuel system mods. Truck drivers pulling trailers regularly benefit most, as the filter's low-restriction design becomes increasingly noticeable under sustained load, reducing engine strain and cooling fan engagement. Installation takes minutes without special tools, and the reusable design means you'll skip recurring filter replacement costs while maintaining consistent airflow characteristics over thousands of miles. Compatible with 2007 and newer Tundras equipped with either V8 platform, this filter pairs well with exhaust upgrades, cold air intakes, or ECU tuning for cumulative performance gains.
