Jeep Wrangler Serious On and Off-Road Performance with a K&N Snorkel Intake System

Any serious off-roader installs a snorkel intake on their JK Jeep Wrangler before heading off-road
Serious off-roaders understand the value of a snorkel intake and many would not take on a challenging trek without their Jeep being equipped with one. That’s why K&N developed the 63-1574 AirCharger intake system for 2007 – 2011 Jeep Wranglers with the 3.8L V6 engine.
The 3.8L V6 was based on Chrysler’s 3.3L narrow-angle 60-degree V6 engine, of which nearly 5 million of the smaller displacement engine had been produced. While the 3.8L (230.5 CID) V6 saw duty in various mini-vans, it was installed in only one Jeep model: the 2007 – 2011 JK Wrangler.
The 3.8L V6, code named the EGH, was manufactured in Chrysler’s Trenton, Michigan engine plant. The increase in displacement was achieved by both increasing cylinder bore and crankshaft stroke. The EGH featured a cast iron engine block with forged steel connecting rods and aluminum cylinder heads with a single central camshaft, roller tappets, pushrods, and overhead valves. Fuel delivery was by sequential multiple-port fuel injection.
From 2007-2011, JK Wrangler customers had to make do with the 202 horsepower EGH V6. However, in 2012 Jeep began installation of the Chrysler Pentastar 3.6L V6 engine, which boosted power to 285 horsepower, leaving owners of previous model years over 80 horsepower short of the new models.
The K&N AirCharger kit comes complete from snorkel to the intake manifold connection
The K&N 63-1574 AirCharger system can help. Its snorkel system, which is specifically designed for the JK Jeep Wrangler, features high-flow air ducting that adds an estimated 11.32 horsepower to the 3.8L V6 Jeep. The AirCharger system replaces the entire restrictive factory intake, including ducts and filter. Why? K&N AirCharger systems are designed to dramatically reduce air intake restriction, delivering more fresh air to your engine than the factory air filter assembly. The equation is simple: more fresh, cool air into the engine means more usable power and acceleration throughout the RPM range.
The uniquely designed snorkel system that’s a key component of the K&N 63-1574 AirCharger system brings in outside air from an ideal location to allow you to ride your Jeep hard in extreme off-road conditions. Fresh air is directed through the low-restriction snorkel tubing and into a tough K&N roto-molded air box that contains a RF-1048 7.5-inch K&N high-flow air filter.
The Roto-Molded air box features a cover to allow for easy access to the oversized air filter
An aerodynamically engineered high-density intake tube smooths and straightens the air flow before its fed into the engine’s throttle body for a guaranteed power gain. The intake tube has provisions to install the stock intake air temperature sensor, and engine breather hose. The oversized RF-1048 cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on your driving conditions. And servicing is simple with the K&N 99-5000 filter care service kit.
The K&N 63-1574 was designed for the following vehicles:
