Cold Air Intake for Nissan Xterra (2000-2003) 3.3L V6 Naturally Aspirated & Supercharged Engines

Optimized Airflow and Thermal Management for the Nissan Xterra VG33E & VG33ER

Who It’s For: Designed specifically for 2000-2004 Nissan Xterra owners running the rugged VG33 family of engines, including both the naturally aspirated VG33E and the factory-supercharged VG33ER variants.

The Problem: The factory intake system on the VG33E was designed for noise suppression and cost-cutting, not for maximum volumetric efficiency. The stock plastic airbox acts as a significant heat sink, especially during slow-speed trail crawls where engine bay temperatures skyrocket. For those running the supercharged VG33ER, this restriction is even more detrimental, as forced induction systems are hypersensitive to intake air temperatures (IATs) and pressure drops.

The Solution: We engineered this kit to replace the restrictive corrugated factory tubing with mandrel-bent T304 aluminum. By incorporating a dedicated heat shield, this system isolates the high-flow filter from the radiant heat of the VG33 engine, ensuring a denser, cooler oxygen charge. This corrects the factory design flaws, delivering more consistent power delivery and a much-needed improvement in throttle response for the WD22 chassis.

Why This is the Ultimate Upgrade

• Enhanced Power Band: Provides a measurable gain of up to 10% in horsepower and torque by reducing pumping losses, allowing the VG33E to breathe more freely at higher RPMs.
• Superior Thermal Rejection: The integrated heat shield prevents the "hot air intake" effect common with cheaper open-filter kits, which is critical for maintaining timing advance on the supercharged VG33ER.
• Built for the Long Haul: Constructed from T304 aluminum and paired with a washable, high-flow cotton gauze filter, this kit is built to withstand heavy off-road vibration and dusty trail conditions.
