The K&N 77-9023KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Toyota 4Runner 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 77-9023KP 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 regulator vacuum 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 screwdriver, pliers, a ratchet set and some Allen 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.

Recently purchased a 2006 V6 4 Runner Sport Edition.  Love the truck but gas mileage and engine performance were just ok.  I was getting 18.5 to 19.5 in town if I was careful.  Just installed the K & N Air Charger System.  I'm not a great mechanic but still found it relatively simple with your directions.  It's hard for me to believe but gas mileage has increased to 23.5 to 24 if I can keep my foot out of it.  Love the engine sound.  Everything about the vehicle is smoother and with the price of gas this will pay for itself in no time.  The truck is quicker off the start and pulls much harder all the way through the power band.

You guys claim an increase of 9.5 HP but the seat of my pants say your selling yourself short.  Love the product.

My friend who races go carts advised me on the K&N oil filters. This will be my second oil change using them on my 2006 Toyota 4 Runner. I can't tell how they are working but I trust my friend and will be using the K&N oil filters from now on.

 When I heard about K & N filters I was a bit skeptical.  I first got my mechanic's opinion before making a purchase.  Bottom line was that it cost $22 more initially than a standard Toyota air filter, but I was banking on the longevity of the filter to be a good investment.  I usually drive my vehicles about 200,000 miles before a new purchase.

 We just returned from a five state, 3,273 mile road trip.  I drive a 2005 Toyota 4 Runner and never got over 20.9 MPG before my K & N install.  On this trip I got up to 24.3 MPG, but never less than 22.5 MPG.  Overall average was about 23.5 MPG.  In effect the filter has already paid for itself, and I am confident that this will be the last filter I need to buy for this vehicle.  Good for me and good for the environment.

  My only regret?  I didn't do this sooner.  Any plans for the future?  Yep!  I'll be buying K & Ns for my other vehicles....
