Product Details

The Sniper EFI Sheet Metal Fabricated Intake Manifold is engineered for GM LS1, LS2, and LS6 engines, delivering enhanced airflow and performance in a lightweight, durable package. Constructed from 3mm (1/8") thick T6061 sheet aluminum and 100% TIG welded, this manifold combines strength with a striking silver finish for aggressive under-hood styling.

Key Features:

  • Single 4150 carburetor flange for maximum airflow and compatibility with throttle bodies
  • Tapered intake runners designed to increase air velocity and evenly distribute airflow to all 8 cylinders
  • Accepts EV1 style fuel injectors only
  • Includes 3/8" fuel rail kits with laser-engraved Sniper logo
  • Complete gasket and hardware kit included for hassle-free installation
  • 100% TIG welded T6061 aluminum construction for superior strength and durability
  • High-impact silver finish for premium under-hood appearance

This intake manifold is designed to improve throttle response and overall engine performance by optimizing airflow distribution across all cylinders. The fabricated sheet metal design reduces weight while maintaining structural integrity, making it an excellent choice for street performance and racing applications.
