Weapon-R 501-115-101 Race Sheet Metal Intake Manifold

The Weapon-R 501-115-101 is a high-volume race sheet metal intake manifold engineered to deliver substantial power gains over the factory unit. Constructed from high-grade AL6061 aluminum, this manifold is both lightweight and exceptionally durable, making it a proven choice for performance builds on both naturally aspirated and forced induction setups.

Weapon-R's manufacturing process sets this manifold apart from the competition. Each unit features CNC-machined velocity stacks and flanges that optimize airflow through the intake runners, while the entire assembly is TIG-welded throughout to eliminate the risk of leaks and cracks under high-boost or high-RPM conditions.

Key Features:

• Proven gains of 15–30 hp on naturally aspirated applications
• Proven gains of 45–90 hp on forced induction applications
• Delivers quicker turbo spool and significant top-end power increases over OEM manifolds
• CNC-machined velocity stacks and flanges for optimized airflow
• Full TIG-welded construction prevents leaks and cracks
• High-grade AL6061 aluminum for strength and durability
• Retains ports for all OEM sensors — no sensor relocation required
• No modifications needed for installation — direct bolt-on fitment

Weapon-R's race sheet metal intake manifold is designed for enthusiasts who demand race-proven performance in a direct-fit package. The leak-tested construction and precision-machined components ensure reliable power delivery whether on the street or the track.
