The K&N 77-9037KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Toyota Tacoma 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 77-9037KP 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, crank case vent hose and a replacement silicone fuel pressure vent hose. 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 couple of screwdrivers, pliers, a 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.

My 2015 Tacoma TRD Sport can finally breathe now. If you have a 4.0L engine, then you must purchase and install this K&N Air Intake System. It took about two hours to install - no issues. The horsepower increase is very noticeable. I can also merge into traffic with no problem. The engine sound is incredible too. One other bonus that hasn’t been mentioned is that when you remove the factory restrictive stock air intake system, you can now access the right side spark plugs with ease.

The sound of the engine is incredible when you step down on the gas. Video on YouTube doesn't do it justice.

Great product !! It took my son-in-law and I less than a hour to install, and we know nothing about cars.
