The K&N Dryflow Air Intake System Toyota Tundra V8-5.7L 12-21 uses an oil-free synthetic Dryflow filter on a custom intake tube, in place of the factory air filter and intake housing. The maker lists a typical installation time of under 60 minutes.

The K&N DRYFLOW Air Intake System replaces your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The DRYFLOW Air Intake System features an oil-free synthetic filter media providing increased airflow and exceptional engine protection without requiring oil. The system can typically be installed in less than 60 minutes.
