2020-2026 LM2/LZ0 3.0L Duramax Throttle Valve Upgrade by VSE Engineering

Upgrade your Factory LM2 & LZ0 Intake Air Control Valve

The 3.0L Duramax features a 2.09 inch inlet and has a throttle blade affixed to a blade retainer. This is the largest flow restriction point in the LM2 & LZ0 intake tract with every other point being larger than 2.09 inches. Our upgraded IAV Features a 2.26 inch inlet and no blade to restrict flow.

Removal of the throttle blade means removing the possibility of the 2 fastener screws from backing out and being consumed by the motor.

We also incorporated 1 NPT connection point for adding a mechanical boost gauge or water/meth or performing a simple boost leakdown on the system

Features:

• No throttle blade (race use only)
• 1 NPT connection for connecting Boost, Water/Methanol, Nitrous, or Boost leakdown equipment
• Back cut machined lip for maximum grip on heat exchanger boot
• Will work with factory or aftermarket Heat exchanger boots

Designed to be replaced in under 30 minutes for hassel free installation.
