10 Best Supercharger For Jeep JK Reviews

If you own a Jeep Wrangler JK, you know that overlanding and off-roading demand more low-end grunt and highway passing power. The stock 3.6L or 3.8L engine can feel a bit underwhelming when you’re pulling a trailer or climbing steep trails. Adding a supercharger is the most effective way to transform your JK’s performance, giving you that instant throttle response and extra horsepower where you need it most.

In this guide, we’ll walk through the best supercharger kit available specifically for the JK, along with essential supporting modifications like coolant filters, cold air intakes, 12-volt power adapters for your accessories, and even a hood lock to protect your investment. Whether you’re planning a full forced-induction build or just want to gather the right parts, you’ll find everything you need to make an informed decision.

Edelbrock 1528 E-Force Supercharger Kit – Proven Power for Your 3.6L JK

If you’re serious about adding forced induction to your 2015–2017 Jeep Wrangler JK with the 3.6L engine, the Edelbrock E-Force kit is the gold standard. It delivers an impressive 317 rear-wheel horsepower with a manual transmission (285 RWHP with an auto) and 277 lb-ft of torque (manual) or 235 lb-ft (auto) – all at just 8 psi of boost. The heart of the system is an Eaton TVS 1320 twin-screw supercharger, which is known for its compact design and instant boost response.

You’ll appreciate that this kit is engineered for a direct fit, meaning you don’t have to hack up your JK’s engine bay. The included intercooler and tuning (via a supplied calibration device) ensure reliable performance. Edelbrock’s reputation for quality means you get a supercharger that’s not only powerful but also durable enough for daily driving and off-road use. Installation is rated as moderate, but having a professional do it is recommended to get the most out of the tune.

njxbrek Universal Supercharger Kit – Budget Option for Low-Displacement Mods

If you’re on a tight budget or building a custom project car, this universal supercharger kit from njxbrek might catch your eye. It’s designed for engines below 3.5L and claims to work with vehicles like the Jeep Cherokee, Toyota Previa, Buick GL8, and HOVER. The housing is made of aluminum with a sand-blasted finish for corrosion resistance, and it includes basic components to add boost.

However, keep in mind that this is not a plug-and-play solution for your JK. The instructions strongly recommend professional installation, and you’ll need to verify fitment carefully because dimensions vary. While it may increase power and reduce fuel consumption in theory, results are unpredictable without proper tuning. For most JK owners, the Edelbrock kit is a far safer and more effective choice, but this universal kit could work for a custom fabrication project if you’re handy with welding and ECU tuning.

LGNHOPR Cold Air Intake Kit (Black) – Increased Airflow for 3.6L JK

To get the most out of a supercharger, you need a free-flowing intake. This LGNHOPR cold air intake kit is designed for 2012–2018 Jeep Wrangler JK with the 3.6L V6. It replaces the restrictive factory airbox with a high-flow intake tube and a washable air filter. The black powder-coated tube looks sleek under the hood.

The intake is designed for good sealing to prevent air leaks, and the hose material is durable for long-term use. By increasing intake volume, it helps the engine breathe better, especially when paired with a supercharger. It’s easy to install and comes with all necessary hardware. However, note that this is a cold air intake, not a supercharger itself – it’s a supporting mod.

• 1. have good sealing performance to prevent intake air leakage and ensure the normal operation of the engine
• 2. The intake hose is used for a long time in various working conditions, reducing the frequency of replacement
• 3. By increasing the intake volume, the combustion is more full, thus significantly improving the engine's dynamic performance.
• 4. Its main role is to evenly distribute air intake to each cylinder to ensure that each cylinder can get the right amount and uniform mixture.
• 5. Through the internal design and structure, minimize the resistance of the air flow and improve the intake efficiency, thereby improving the performance of the engine.

LGNHOPR Cold Air Intake Kit (Red) – Same Great Performance, Different Color

If you prefer a splash of color under the hood, the red version of the LGNHOPR cold air intake kit offers identical features to the black model. It’s also compatible with 2012–2018 JK 3.6L engines, providing improved airflow and a sporty look. The red intake tube stands out and adds a visual upgrade to your engine bay.

All the same benefits apply: good sealing to prevent leaks, durable hoses, and increased intake volume for better combustion. Whether you choose black or red, this intake is a worthwhile addition whether you’re supercharged or staying naturally aspirated. Just be aware that for forced induction, you may need a larger intake or blow-off valve provisions – but this is a fine starting point.

Buyer’s Guide: What to Consider

Choosing the right supercharger for your Jeep JK involves more than just picking the biggest power number. You need to match the system to your engine, budget, and intended use. This buying guide covers the critical factors to consider before you start ordering parts, so you can build a reliable and powerful JK that handles the boost day in and day out.

• Engine Compatibility: Ensure the supercharger kit is specifically designed for your JK’s engine: 3.6L (2012–2018) or 3.8L (2007–2011). Most dedicated kits only fit the 3.6L. The 3.8L requires custom solutions. Also check transmission type – manual vs. auto affects power numbers.
• Boost Level and Tuning: Superchargers like the Edelbrock run at 8 psi, a safe level for the stock internals. Higher boost may require forged pistons, stronger rods, and custom tuning. Always include a quality tune – many kits come with a handheld tuner. Without proper calibration, you risk engine damage.
• Installation and Support: Decide whether you’ll install yourself or hire a shop. Dedicated kits for the JK are more straightforward than universal ones. Check if the kit includes clear instructions, hardware, and technical support. Professional installation is recommended for forced induction to ensure proper belt alignment and cooling.
• Supporting Modifications: A supercharger increases heat and stress. Plan for upgrades like a larger radiator, intercooler (included in Edelbrock), cold air intake, and coolant filter (like the Mishimoto). Also consider a stronger clutch for manual JKs or transmission cooler for autos. Fuel system upgrades (larger injectors, fuel pump) may be needed for high boost.
• Warranty and Quality: Reputable brands like Edelbrock offer solid warranties and proven performance. Cheaper universal kits have no support and may damage your engine. Investing in a quality supercharger saves money in the long run. Also check that supporting parts (intakes, filters, power adapters) are from trusted manufacturers.
• Budget and Long-Term Costs: A complete supercharger kit can cost several thousand dollars. Factor in installation, tuning, and supporting mods. A budget universal kit might seem cheaper but often requires custom fabrication, additional parts, and dyno tuning, ultimately costing more. Plan your entire build budget upfront.
• Legal and Emissions Compliance: Some supercharger kits are CARB exempt in California, but most are not. Check your local laws before installing. Cold air intakes may also affect emissions compliance. The Edelbrock kit is 50-state legal when used with provided calibration, but always verify with your state’s regulations.

Conclusion

After reviewing the options, the Edelbrock 1528 E-Force Supercharger Kit stands out as the best choice for Jeep JK owners with a 3.6L engine. It delivers substantial power gains, comes with a proven Eaton TVS supercharger, and includes everything needed for a professional installation. It’s the only dedicated supercharger kit in our roundup, and it’s backed by years of engineering.

To complete your build, don’t forget the supporting accessories: a coolant filter to protect your cooling system, a cold air intake for better flow, a 12V power adapter for your gauges, and a hood lock to secure your investment. Whether you’re tackling Moab or daily commuting, the right supercharger setup transforms your JK into a true performance machine. Start with the Edelbrock kit, add these proven upgrades, and enjoy the extra horsepower with confidence.
