Jeep Engine Performance Parts

Performance Parts

Performance exhaust, electronics and air filters and intakes are a few of the performance parts that keep your Jeep functioning optimally and efficiently. Top manufacturers like aFe, Superchips, MagnaFlow and Dynomax all create cutting-edge products for various applications. 4WD offers a myriad of solutions for all budgets and enhancements when you need to upgrade factory parts that are not performing to your standards. Entire systems or individual components can be replaced quickly and conveniently to have your Jeep taking command and conquering challenging terrains.

Riding trails stresses your Jeep’s engine, heating and cooling parts more than normal wear-and-tear of the street, so make sure your rig is trail-ready with Jeep performance parts that will keep you ready to go at a moment’s notice.

Performance Jeep Parts for the Trail
Hi-revving crawls in low gear tax your Jeep’s engine and cooling system, and a breakdown on the trail is every jeeper’s worst nightmare. Buy a little insurance by modding your engine for reliability and power.

From the top down, your Jeep’s engine is engineered for reliability, efficiency and power. It was also mass produced and designed with a budget in mind, so the aftermarket has superior parts to OEM Chrysler parts. 

The best place to start adding Jeep performance upgrades is through a cold-air intake. A cold-air intake lets your engine breathe better, making it more efficient. Cold air is denser than hot air, and cooler air has more oxygen in it, offering a gain in performance. 

The next step a lot of jeepers make is to replace the factory exhaust with a performance-minded setup. Like a cold-air intake, these offer better engine ventilation and give your rig a note of authority on the trail and street. 

Other common mods and their benefits are:

- Tuner: This plugs into your Jeep’s PCM (computer) and changes parameters such as shift points, economy and timing.
- Throttle body: This lets air into your engine, and having a performance-tuned or bigger unit lets your Jeep breathe deeply more efficiently and effectively.
- High-quality filters: You want your Jeep’s engine to last a long time and run well during its life, so treat it to the best oil and fuel filters you can afford.
- Gauges: Keep an eye on your motor and temps with oversize gauges without taking your eyes off the trail. It just makes sense.

Regardless of the goals for your Jeep, 4WD.com has everything you need to take it from mild to wild.
