K&N 00-04 Nissan Xterra V6-3.3L Performance Intake Kit K&N Engineering 57-6005

The K&N 57-6005 FIPK 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 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 57-6005 air intake comes with a K&N XStream Top air filter designed for higher air flow and durability. A heat shield installs into the previous air box space that directs air through an intake tube into the engine's throttle body for a guaranteed power gain. The oversized air filter accommodates the factory air temperature sensor and can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points and requires 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.
