    Description

    Improved Turbocharger Response. By blocking the exhaust pressure control port, this blocker ensures more consistent exhaust flow to the turbocharger, resulting in crisper throttle response and reduced lag under load. The PPE EPC Blocker installs in place of the factory exhaust pressure control valve, delivering reliable performance without the complexity of additional electronics.

    Durable, Maintenance-Free Design. Constructed from high-strength aluminum with a corrosion-resistant anodized finish, the PPE EPC Blocker resists heat and chemical exposure, maintaining a leak-free seal and eliminating a common failure point in Duramax engines.

    Installation. This product installs by removing the factory EPC valve, bolting the PPE blocker into the original flange, and tightening to specification—basic hand tools required.

    Application. This PPE EPC Blocker fits 2011–2019 Sierra 2500 HD trucks equipped with the 6.6L Duramax engine and Allison transmission without modification.
