When the 3.6L Pentastar V6 was introduced in the updated 2012 Jeep Wrangler JK, it brought a nice bump in horsepower. The strong, smooth engine was a substantial improvement over the 3.8L it replaced. But, for many Jeep enthusiasts—and Summit Racing Equipment customers—more power simply isn’t enough. Maybe your JK or JL Wrangler is rolling on massive tires. Maybe you tow a camper, side-by-side, or utility trailer. Or maybe you like to ride high-elevation mountain trails, where the thin air saps your power. Whatever the reason you want more power and torque under your right foot, a Roots-style supercharger kit from Summit...

What does a supercharger do?

In the simplest terms, if you can get more air into an engine, you can burn more fuel and make more power. A supercharger is a pump, usually belt-driven off the engine’s crankshaft, that packs more air into the engine. A Roots-type supercharger, or blower, as they’re often called, accomplishes this with a pair of interlocking three- or four-lobe rotors. These positive-displacement superchargers move a fixed amount of air per revolution, creating immediate boost for strong low- and mid-range power; right where you need it in a Jeep.

How much more power can I expect with a Roots-type supercharger?

Power gains vary depending on the kit, vehicle model year, and transmission. Typically, most kits offer around 50% more power than stock, for over 300 horsepower at the wheels in a modern Jeep Wrangler. When you consider that the stock 3.6L engine in the Wrangler JK and JL produces 285 crank horsepower, it becomes apparent that a supercharged Jeep will accelerate, climb, and pull like a completely different vehicle.

Will a Roots-style supercharger kit fit my Wrangler?

Application-specific Roots-style supercharger kits are available for 2012-25 Jeep Wrangler JK and JL vehicles equipped with the 3.6L Pentastar V6, excluding eTorque hybrid models. They bolt on with no cutting, welding, or permanent modifications, for a factory look and fit.

What else will I need?

Aside from tools and engine coolant, these kits come complete with everything you need for installation including:

Supercharger
Intercooler
Intake ducting
Cooling hoses
Serpentine belt and drive components
Fuel injectors
Wiring harness
Hardware
Gaskets
Detailed instructions
And more

Also, with many kits, a 50-state-legal ECM tune is included, using either a provided tuner or by sending your ECM to the supercharger manufacturer for reprogramming.
