The 1GR-FE 4.0L V6 engine is well known for its lack of low RPM power, resulting in sluggish throttle response, weak acceleration, reduced fuel efficiency, and underwhelming performance in off-road or heavy load situations. This billet aluminum intake manifold adapter addresses that directly by extending the intake port by 1 inch, allowing the engine to reach its maximum torque at lower RPMs for noticeably improved throttle response and pulling power. CNC machined to precise tolerances and finished with a smooth anodized surface, it mounts directly between the intake manifold and intake manifold base using the same size sealing gasket as the factory unit — no cutting, welding, or custom fabrication required.

Features:

• Billet aluminum construction – lightweight, high-strength, and built to withstand engine bay heat and vibration
• CNC machined to tight tolerances for a precise, factory-quality fit between the intake manifold and manifold base
• Smooth anodized surface finish – corrosion resistant and less prone to oil vapour buildup and carbon deposit accumulation
• 1-inch extended intake port improves low RPM torque output, allowing maximum torque to be reached at lower engine speeds
• Same size sealing gasket as the factory manifold – ensures a tight, leak-free installation
• Mounts directly with all extension spacers and hardware included – no additional parts required
