2007 to 2011 Toyota Tundra Owners Find 13.05 Horsepower by Adding K&N Performance Air Intake System

The Toyota Tundra is one of the most popular choices among today's truck buyers. With an ergonomic interior and a powerful 5.7 liter engine, the truck is a pleasure to drive. Now, 2007, 2008, 2009, 2010 and 2011 Tundra owners can find 13.05 more horsepower at 5282 RPM hidden behind their restrictive factory air intake system by adding K&N's new high-flow intake system for the Tundra 5.7.

K&N's intake system part number 63-9031-1 replaces the factory air box and air path leading to the engine. In its place, a K&N oversize conical air filter is mounted inside a powdercoated heat shield that isolates the filter from the rest of the engine compartment. The filter supplies clean and unrestricted air flow to a rotationally molded intake tube which has been shaped to optimize air flow to the engine. The factory mass airflow sensor is relocated into the K&N intake tube using a special adaptor, and no reprogramming or computer modifications are necessary when using this system. The cold air intake system offers more performance while providing excellent filtration.

The oversize, chrome top RF-1041 air filter supplied with the intake offers the best balance of high air flow and filtration efficiency. Inside the filter, multiple layers of cotton are treated with 1.67oz of K&N air filter oil, which traps and holds dust particles while allowing air to pass by with little restriction. The filter's size allows it to go up to 100,000 miles before cleaning is necessary.

The 63-9031-1 attaches using all existing mounting points, and requires no cutting or drilling. It can be easily installed in 90 minutes or less with a socket set, wrenches, and screwdrivers. The system is also backed by K&N's Million Mile Limited Warranty.
