Cold Air Intake for Buick Lesabre Park Avenue (2000-2005) 3.8L Engine

Breathe New Life into Your Buick LeSabre & Park Avenue Series II 3800

Who It’s For: Designed specifically for 2000-2005 Buick owners running the legendary Series II 3800 V6 engine. This is for the driver who wants more passing power on the highway and a more responsive feel around town without sacrificing the rock-solid reliability this platform is known for.

The Problem: The stock intake on the Series II 3800 is a massive, multi-chambered plastic resonator box designed for total silence, not flow. Between the accordion-style plastic tubing and the restrictive paper filter, your engine has to fight for every breath of air. Over time, these factory plastic components become brittle from engine bay heat, often leading to hairline cracks and unmetered air leaks.

The Solution: We engineered this system to replace the factory restriction with mandrel-bent T304 aluminum. By providing a smooth, straight-shot induction path, we significantly reduce turbulence and allow the Series II 3800 to reach its peak volumetric efficiency. It doesn’t just perform better; it gives the car a sophisticated, throaty growl under load that the factory air box hides.

Why This is the Ultimate Upgrade

• Enhanced Induction Flow: Mandrel-bent T304 aluminum piping eliminates the turbulence caused by the factory corrugated plastic hoses, resulting in up to a 10% gain in horsepower and torque.
• Superior Filtration: Includes a high-flow, washable synthetic filter that provides exceptional filtration while allowing a higher volume of air to reach the throttle body.
• Bulletproof Construction: Unlike the stock plastic that warps and cracks with age, this aluminum system is built to last the life of the vehicle and adds a clean, professional look to your engine bay.
