Weapon-R 501-112-413 High-Volume Sheet Metal Race Intake Manifold

The Weapon-R 501-112-413 is a high-volume, sheet metal race intake manifold engineered to deliver significant horsepower and torque gains over the restrictive OEM factory manifold. Constructed from high-grade AL6061 aluminum billet, this manifold is designed for both naturally aspirated and forced induction applications.

Key Features:

• Proven gains of 15–30 hp on naturally aspirated applications and 45–90 hp on forced induction setups
• Improves turbo spool response and increases top-end power over the stock OEM manifold
• CNC-machined velocity stacks and flanges for precise airflow and consistent fitment
• Fully TIG-welded construction throughout to prevent leaks and cracks
• Built from high-grade AL6061 aluminum for superior durability, strength, and reduced weight
• Each manifold is pressure-tested for leaks and pinholes prior to shipping
• Retains ports for all OEM sensors — no modifications required for installation
• Fully bolt-on application; no cutting, drilling, or fabrication needed
• Capable of holding up to 45 PSI
