Performance Mods

More airflow, better throttle response. Check CARB EO numbers if you live in a strict-emissions state.

Sound and modest power gains without touching emissions equipment.

Handheld tuners unlock timing/shift tweaks. Always save your stock tune.

Lower for handling or lift for clearance – match to your use case.

Use the viscosity and spec (API/dexos/etc.) in your owner's manual.

Ceramic for low dust daily driving; semi-metallic for towing and heat.

Iridium plugs last ~100k miles. Gap-check before install.

Match group size, CCA, and AGM vs flooded to the OEM spec.

Filter by year/make/model/engine. Watch for mid-year changes and trim-specific brake sizes.

Confirm cab/bed length, 2WD vs 4WD, and GVWR before suspension or exhaust parts.

JK vs JL vs JT parts rarely cross over. Check axle (Dana 30/44) and gearing for lifts and tires.

AWD systems often need matched tires; check hitch class and towing ratings.

Tip: use Amazon's "Your Garage" fitment check and verify against the OEM part number.

Tires, brake pads, and fluids beat power mods for real-world performance per dollar.

OEM guarantees fit; reputable aftermarket brands often match quality for less. Avoid no-name brake and steering parts.

The Magnuson-Moss Act protects your warranty, but emissions-tampering parts are illegal on street vehicles.
