Open the intake path on a competition-use 3.0L LM2 or LZ0 Duramax with VSE's throttle valve upgrade. The blade-free design increases the inlet diameter from the factory 2.09 inches to 2.26 inches and eliminates the original throttle blade and its retaining screws.

• Application: 2020-2026 LM2/LZ0 3.0L Duramax.
• One NPT connection supports a boost gauge, injection accessory or pressure-test connection.
• Machined retaining lip helps secure the charge-air boot.
• Compatible with factory or aftermarket charge-air boots.

Application notes: VSE specifies race applications only and requires custom tuning.
