K&N BORLA T-304 Stainless Steel Cat-Back™ Axle-Back™ System & 63 Series AirCharger® Performance Intake for 2011 Jeep® Wrangler & Wrangler Unlimited JK 3.8L

Get more performance out of your Jeep with two of the best names in intake and exhaust. K&N's Fuel Injection Performance Kits (FIPK) are designed to promote performance in stock fuel injected engines by allowing air filtration with least resistance in air flow. Combine that with a Borla exhaust kit for the ultimate in performance! All Borla systems feature tough 16-Gauge T-304 Stainless Steel construction. It's so tough that Borla backs each system with a Million- Mile Warranty. Adds throaty sound characteristics, and provides mild performance gains with tuned exhaust flow.

Borla Performance Industries has a grand heritage with Jeep exhaust Cat-backs™ and Headers. The performance is legendary and the durability just what these recreation vehicles need. If you are into getting out in the back-country, these new Jeeps are the ticket. If you live in country where the elements include severe weather, this could be your everyday driver. BORLA has introduced a pair of impressive exhaust rear sections for both the 4-door and 2-door Wranglers. The rear-sections connect to the factory mid-pipe. Choose from the split rear dual system (PN11755) or the single exit (PN11754). Both systems increase power, decrease weight, include handsome polished stainless steel BORLA tips and add durability to the adventurous Jeep Wrangler. Couple all this with the great BORLA sound of power, and you just want to jump in and go for a Jeep ride.
BORLA, the original pioneers of high quality, austenitic stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy -- all with an easy bolt-on installation. And backed by an unsurpassed written million-mile warranty.
A sister product to the 57 Series FIPK, the 63 Series Intake Kits or AirCharger® Intakes are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone. They enjoy a faster speed to market than the 57 Series kits due to their pending CARB status. These intakes use only non-metallic rotationally molded tubes that can reduce intake air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 63 Series Intake Kits are not legal for street use in some U.S. states.The filter recharger kit is sold separately.63-1553 Product Specifications
