Unlock the hidden potential of your GM 4.3L, 5.0L, or 5.7L engine. This Performance Cold Air Intake eliminates factory restrictions to deliver a 10% power boost, sharper throttle response, and a rugged engine growl.

Give Your Vortec Engine the Breath of Life and Power It Craves

The 1996–2000 GM truck era defined American reliability, but the factory intake system was designed more like a muffler than a performance part. If you’re towing a trailer through the mountains or merging onto a busy highway, that restrictive plastic air box is starving your engine of the oxygen it needs to perform. It creates internal turbulence that kills your momentum and leaves your 5.7L or 5.0L feeling sluggish under load.

Our Performance Cold Air Intake System transforms your engine into a high-efficiency air pump. By replacing the baffled factory tubing with smooth, lightweight T304 aluminum, we deliver a high-velocity, oxygen-rich charge directly to your intake manifold. The result? A noticeable gain of up to 10% in horsepower and torque, ensuring your C/K 1500 or Tahoe has the "get up and go" to handle any job with confidence.

Engineered for the Long Haul

Maximum Airflow Velocity: T304 aluminum induction tubing minimizes air friction, providing a more direct connection between your foot and the pavement.
Enhanced Towing Performance: Gain the extra edge needed for heavy hauling by providing cooler air for more efficient combustion.
Precision Filtration: Includes a washable, high-flow air filter that catches debris without sacrificing the massive air volume your V8 demands.
The "Vortec Growl": Beyond the power gains, this system unlocks a deeper, more aggressive engine note that lets people know your truck means business.

Built for Easy DIY Installation

You don't need a professional shop to see professional results. This kit is designed for a direct bolt-on installation, fitting both automatic and manual transmission models. By disconnecting your negative battery cable during the 45-minute install, you allow your GM’s ECU to reset and recalibrate to the new, higher oxygen levels immediately—optimizing your air-to-fuel ratios for peak performance right out of the driveway.

Durability That Matches Your GM Heritage

Truck owners know that heat is the enemy of performance. The lightweight T304 aluminum used in our piping offers superior heat dissipation compared to stock plastic or inferior steel tubes. This ensures that even in stop-and-go traffic or under the desert sun, your intake air stays cool, dense, and ready to ignite.

Why This Upgrade is a Must-Have:

Horsepower Gain: Up to 10% increase across the entire power band.
Improved Fuel Efficiency: Better airflow means your engine doesn't have to work as hard to maintain cruising speeds.
Rugged Durability: T304 Aluminum resists corrosion and withstands the vibrations of off-road use.
Aggressive Aesthetics: Replaces the bulky, ugly plastic factory box with a sleek, high-performance look.

Panel popper tool (or needle-nose pliers)
Silicone spray or soapy water
Dedicated MAF Cleaner

Mechanic’s Pro Tip (The "Gotcha"):
For the GMT400 OBS guys: the factory Vortec air hat and plastic tubing are notoriously brittle after two decades of heat cycling. When removing the factory tubing, be extremely gentle with the inline Mass Air Flow (MAF) sensor and the push-in Intake Air Temperature (IAT) sensor. Don’t pry on the MAF housing—it will crack. If the old rubber grommet for the IAT sensor is hard as a rock, hit it with a little silicone spray before pulling. Unmetered air leaks from cracked plastics are the number one cause of rough idles on these L31/L30 engines!

Phase 1: Removing the Factory Part

Disconnect the Battery: Always start by disconnecting the negative battery terminal using a 10mm wrench to prevent check engine lights and clear the ECU memory.
Unplug the Sensors: Carefully depress the locking tabs and unplug the wiring harnesses from the MAF sensor and the IAT sensor. Use a panel popper tool to gently free any plastic wire harness clips secured to the factory intake tube or airbox.
Remove the Factory Vortec Hat: Loosen the wing nut or the top mounting bolt holding the bulky plastic resonator hat to the top of the throttle body. Disconnect the crankcase breather hose from the side of the hat.
Loosen the Clamps & Pull the Tube: Use your 8mm nut driver to loosen the hose clamps securing the intake tube to the MAF sensor housing. Gently twist the tubing to break the seal and remove it from the engine bay.
Extract the Airbox: Unbolt the factory airbox from the passenger side fender using a 10mm socket and remove the assembly entirely. Keep the factory hardware; you will need it to mount the new aftermarket heat shield.

Phase 2: Installing the Cold Air Intake for 1996-1999 Chevrolet GMC C/K Trucks 5.0L 5.7L

Assemble the Heat Shield: Bolt the new aftermarket heat shield into the factory airbox location on the fender using the factory bolts and your 10mm socket. Install the provided rubber edge trim around the shield to prevent chafing on the new tubing.
Transfer the Sensors (CRITICAL): Gently remove the IAT sensor from the factory tube. Spray a tiny bit of soapy water or silicone spray on the new intake tube’s rubber grommet and carefully press the IAT sensor into place. Transfer the MAF sensor into the new silicone couplers. Do not touch the delicate hot wires inside the MAF! If it’s dirty, clean it now using only Dedicated MAF Cleaner.
Route the New Intake Tube: Slide the new aluminum or poly intake tube into the silicone couplers at the throttle body and the MAF sensor. Attach the new provided crankcase breather hose to the factory valve cover port and the fitting on the new intake tube.
Tighten All Hardware: Go over all your worm-gear clamps with an 8mm nut driver. Snug them down firmly, but do not overtighten and crush the plastic MAF sensor housing. Reconnect the MAF and IAT wiring harnesses until you feel them "click".
ECU Relearn & First Startup: Reconnect the negative battery terminal with your 10mm wrench. Start the truck, but do not touch the gas pedal for at least 20 seconds. Allow the ECU to read the new airflow volume and adjust the idle parameters automatically.
