The K&N 77-1553KP Air Intake fits some Jeep Wrangler models. See vehicle applications link for details.
The K&N 77-1553KP 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 77-1553KP air intake comes with a black rubber 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 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 and ratchet set. 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.

K&N 77-1553KP Air Intake Product Reviews

Monday, October 10, 2016 - Part 77-1553KP
I have not had enough experience with the new air intake system to say for sure that I can tell a difference. What I have noticed appears to have improved mileage some, but not dramatically. Most recent trip, mostly highway with some city averaged 20.5 mpg.

Very easy to install..... 7 horse is not a lot but if you own the 2011 Rubicon, you can feel the difference...

Easy to install, and noticed improvement on my 2010 Jeep Wrangler sport mpg. This is the third one I have had and will continue to get one for every vehicle I own.

I bought a programmer and didn't notice ANY gain so I bought this K&N filter and immediately noticed HP. I can't tell exactly but it was worth the money. It took my boy 20 minutes or less to install. Love having him in the garage with me. His 3.8L Jeep has a nice sound too when you step on the gas.

Very pleased with the item. It was easy to self-install and has resulted in the additional power pickup for our Rubican JEEP that we expected. My son is proudly exhibiting your K&N sticker on the Jeep.
