Turbosmart TS-0550-3098 ALV40 4-1 Outlet Weld Flange Anti-Lag Valve 4 & 8 Cyl

Vehicle Fitment

• Universal - compatible with any 4-cylinder or 8-cylinder turbocharged engine equipped with a Turbosmart ALV40 Fresh-Air or Bypass Anti-Lag Valve requiring a 4-into-1 outlet flange configuration

Fitment Notes

• This is an accessory/spare part for the Turbosmart ALV40 Anti-Lag Valve - the ALV40 unit must be purchased separately
• 4-1 configuration routes four individual 19mm cylinder outlet ports into a single merged outlet; required for 4-cylinder engines (and 8-cylinder engines using dual ALV40 setups)
• Not for use with 3-cylinder or 6-cylinder engines - use TS-0550-3099 (3-1 flange) for those configurations
• Requires welding to the exhaust manifold or cylinder head port; professional fabrication recommended
• Race and competition use only; not CARB legal and not for use on pollution-controlled road vehicles

Features

• Machined in-house at Turbosmart from stainless steel for precise dimensional accuracy and long-term heat resistance at exhaust temperatures
• 4-into-1 outlet design consolidates four individual cylinder anti-lag air passages into a single 19mm outlet port for clean, compact plumbing
• Purpose-engineered specifically for the ALV40 range, ensuring correct bolt pattern and port alignment for leak-free fitment
• Available in multiple configurations (2-1 through 6-1) to support different engine cylinder counts within the same ALV40 system

Product Description

The Turbosmart ALV40 4-1 Outlet Weld Flange (TS-0550-3098) is a stainless steel weld-on flange designed to connect the Turbosmart ALV40 Anti-Lag Valve to 4-cylinder and 8-cylinder engines. It consolidates four individual 19mm cylinder outlet ports into a single outlet, allowing the ALV40 to distribute fresh air or bypass charge across all cylinders in the correct configuration for the engine. Machined in-house at Turbosmart, the flange is built to precise tolerances to ensure proper port alignment and a secure, leak-free interface between the ALV40 valve body and the exhaust manifold or cylinder head.

This flange is part of Turbosmart's full ALV40 weld flange range, which spans 2-1 through 6-1 outlet configurations to support different engine cylinder counts. It is an accessory/spare component - the ALV40 Anti-Lag Valve itself is sold separately. Selection of the correct flange configuration is critical to proper anti-lag system operation, as each flange is purpose-built for specific cylinder counts.
