Cold Air Intake for GMC Sierra (2014-2019) 5.3L/6.2L V8 Engines

Your factory intake was designed for one thing: silence. It chokes the airflow to keep your cabin quiet, effectively putting a muzzle on your V8. It’s time to remove the restriction and let that EcoTec3 engine actually breathe.

Performance Cold Air Intake System for Chevrolet Silverado / GMC Sierra / SUV (K2XX Platform)

If you drive a K2XX platform truck or SUV, you know the 5.3L and 6.2L engines are capable powerplants, but they feel lazy off the line. This is largely due to the OEM intake design. The factory setup is full of accordion-style ribbing, resonators, and sound-canceling baffles that create turbulence and restrict air volume. GM designed it to be quiet, not efficient. By forcing air through that convoluted plastic maze, you lose throttle response and peak output.

This aluminum cold air intake deletes the factory "silencer" and replaces the turbulent stock tube with smooth, mandrel-bent T304 aluminum. Aluminum dissipates heat faster than the thick stock plastic and allows for a higher volume of laminar airflow directly into the throttle body. The result is an engine that reacts immediately when you step on the gas, rather than hesitating while it gasps for air.

Beyond the dyno numbers, this upgrade changes the character of the truck. Under normal cruising, it remains civilized. However, under heavy load, you get that deep, throaty induction growl that a V8 is supposed to have. This system is designed specifically for the MAF sensor scaling of the 2014-2019 trucks, ensuring you get the power bump without throwing a Check Engine Light, provided you follow the battery reset procedure.

Why You Need This Upgrade

• Delete the Restriction: Replaces the baffled factory airbox and ribbed tubing for smooth, direct airflow.
• Dyno-Proven Gains: Engineered to boost horsepower and torque by up to 10% by maximizing air volume.
• Hear the V8: Unlocks a deep, sporty intake sound that is audible under acceleration but quiet at idle.
• Maintenance Free: Features a high-flow, washable filter that lasts the life of the truck (clean every 50k miles).
• T304 Aluminum Construction: Lightweight, corrosion-resistant piping looks better in the engine bay than stock black plastic.
• No Tune Required: Designed to work with the factory ECU mapping.

Installation Notes

Installation is straightforward and uses existing mounting points; no drilling or cutting is required. You will need basic hand tools (screwdrivers, socket set) to remove the factory airbox clamps. Critical Step: You must disconnect the negative battery terminal for at least 15 minutes during installation. This resets the ECU's fuel trim parameters, forcing the computer to "re-learn" the increased airflow volume immediately upon startup. Failing to do this may result in a rough idle until the computer self-adjusts over time.
