The K&N 77-9025KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Toyota Tundra models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-9025KP air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive chrome-like finish that's made to last and it accommodates the factory mass air sensor and crank case vent hose as well as a replacement silicone vacuum hose for the fuel pressure regulator. The oversized cone shaped air filter 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 existing factory mounting points. The tools needed are a screwdriver, ratchet set and some wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

I put an air intake system on my 2009 Toyota Tacoma SR5. Took my dumb ass 4 hrs to install. Make sure tube is fabricated facing correct direction. HOLY CRAP!!! It runs and sounds like you just had thousands of $ in performance parts added. Took a friend for a ride the other day after installing a K & N air filter in his 1999 expedition, and taking it for a ride. He could immediately feel and hear the difference the filter had made. When we returned from our ride in the Tacoma he had me order him a K&N air intake system. He said it rode and sounded like a mustang.

I made a really great decision when I purchased this K & N cold air intake for my 2010 Toyota Tacoma. I am very happy with the performance boost, and the increased gas mileage. Couldn't be more pleased!

Outstanding product and customer service! Once I installed the new air filter into my Chrysler minivan, I could definitely tell that the engine was running stronger. This was sort of a confirmation because I had purchased a K & N filter earlier for my Toyota Tacoma and was (am) very happy with the increased performance. I told my brother in law about the filter and he bought one for each of his two vehicles as well. Great job folks and best wishes for continued success!
