Letter The Letter K Worksheets Webtools Letter 'K' Tracing Worksheet. The K&N 57 9027 FIPK air intake system replaces the restrictive factory air filter and air intake tubing in some Toyota Tundra and Sequoia models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57 9027 air intake comes with a custom molded K&N high flow air filter that installs into the factory air box. Air is directed through an aerodynamically engineered intake tube into the engine's throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor, fuel pressure regulator vent line and crank case vent hose. The oversized custom shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake installs in about 90 minutes or less and requires just commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
