The K&N 77-1566KP high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Jeep Wrangler 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 77-1566KP 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 air temperature sensor and a replacement silicone crank case 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 screwdriver, ratchet set and several 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.
The product is great, the process with 4WD.com was easy, just be careful removing the sensor! I will continue to order from 4WD.com
Huge difference! There is a growl tone when you accelerate that the wife was worried about at first. But, judging by the opening of the stock intake hole vs the K&N intake filter, no wonder there is a big difference. Just be careful when installing the sensor in the new tube.
Installation was super easy. Now there is a sound like a growl when I accelerate. I notice a much better throttle response and power to pass on the highway has improved as well. Looks great in the engine bay. Well worth the $$$
Make sure to DISCONNECT that negative terminal on the battery. sounds sexy when the accelerator is pressed.
