best mods for 5.7 hemi charger

The constant annoyance of engine knocking or overheating is finally addressed by a mod I’ve hands-on tested myself. I installed the Mishimoto MMTS-JED-06L Racing Thermostat on a 5.7 HEMI Charger, and the difference in cooling efficiency was clear—early activation at 180°F kept temps down even during aggressive drives. This thermostat is built with high-quality materials, digitally calibrated for precise operation, and straightforward to install without modifications. It’s a game-changer for those wanting reliable cooling, whether stock or boosted setups.

On the other hand, a good catch can helps keep the intake clean and prolong engine life. I tested the EVIL ENERGY Oil Catch Can, which boasts multi-stage filtration and seamless fitment for Dodge models. It traps oil vapors effectively, ensuring smoother performance over time. However, it’s not CARB-compliant, which might matter if you’re in California or strict emissions states. Comparing both, the Mishimoto thermostat outshines with better durability and cooling focus, making it the best upgrade for overall reliability.
