Performance Upgrades Worth Doing
REFERENCE IMAGE
⚡

COLD AIR INTAKE SYSTEMS ($250-450)

Volant, K&N, and Airaid offer excellent options. Expect 10-15 HP gains and improved throttle response. The 5.3L and 6.2L engines love more air.

⚡

EXHAUST UPGRADES ($400-1000)

Corsa, Magnaflow, and Borla deliver power and sound. Cat-back systems add 15-20 HP on V8s. Look for 3-inch diameter for best flow.

⚡

PERFORMANCE CHIPS/TUNERS ($300-500)

Diablosport, Superchips, and Hypertech offer proven tunes. Gains of 30-60 HP possible, plus improved shifting and throttle response.

⚡

THROTTLE BODY SPACER ($100-200)

Simple bolt-on mod that improves low-end torque. Airaid and Jet make quality units.

⚡

SUSPENSION UPGRADES ($600-2000)

Bilstein shocks transform ride quality. Rancho or Fox for serious off-road capability. Add a leveling kit for bigger tires.
