Performance Air Intake for GMC Yukon (1999-2000) 5.7L Engine - Red

Optimize Airflow for Your GMC Yukon & Vortec 5700 V8

Who It’s For: Designed specifically for 1999-2000 GMC Yukon owners running the legendary Vortec 5700 V8 engine. Whether you are towing a boat or just looking for better highway merging power, this is for the enthusiast who knows their Small Block deserves better than a plastic straw for an intake.

The Problem: The Vortec 5700 is a workhorse, but the factory intake system on the 1999-2000 Yukon is plagued by restrictive, baffled tubing and a massive airbox designed more for silence than for performance. This stock setup creates turbulence and heat soak, effectively "choking" the engine’s ability to breathe when you step on the gas.

The Solution: This Performance Air Intake replaces the entire restrictive assembly with T304 lightweight aluminum piping and a high-flow filter. We engineered this part to streamline the air path into the Vortec 5700, reducing intake temperatures and allowing the engine to pull in the volume of air it needs to maximize its factory potential.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: Provides a measurable boost in horsepower and torque (up to 10%) by reducing intake restriction and allowing the L31 to breathe.
• T304 Aluminum Construction: Unlike cheap plastic kits that crack or heat-soak, our T304 aluminum piping reflects heat and stays durable under the harshest engine bay conditions.
• Simple Bolt-On Install: This is a true "driveway upgrade." Using basic hand tools, you can swap your factory box for this high-flow system in under 60 minutes.

The Performance Promise

Expert Tip: After installation, disconnect your battery for about 10 minutes. This allows the PCM to reset its fuel trim tables and "learn" the new, higher volume of air coming through the intake. You’ll notice a crisper throttle response and a much deeper, throaty tone from your V8 engine. Buy with confidence. Backed by real automotive experts and fast shipping.
