BD Diesel 1040310 HX35 Turbo Boost Elbow for 5.9L Cummins

The BD Diesel 1040310 HX35 Boost Elbow is a factory-calibrated wastegate orifice designed to increase turbo boost pressure for 1994-2002 Dodge RAM 2500/3500 trucks equipped with the 5.9L Cummins engine and HX35 turbocharger. This simple yet effective upgrade replaces the brass fitting on the turbo compressor housing to raise boost levels from the factory 21 psi to as much as 35 psi or higher.

Key Features:

• Pre-calibrated to deliver up to 50% more boost during initial acceleration
• Improves throttle response, power output, and fuel economy
• Reduces exhaust gas temperatures (EGTs) and black smoke
• No adjustment or tuning required—factory pre-set for optimal performance
• Installs in approximately 15 minutes with basic hand tools
• Ideal complement to fueling upgrades such as performance injectors or fuel plates
• Works with stock HX35 and HX40 turbochargers

This boost elbow is particularly beneficial for trucks with fueling modifications that require additional boost pressure to efficiently burn the extra fuel. By maintaining more consistent boost pressure throughout the power band, it helps your engine produce more power while running cleaner and cooler. BD Diesel recommends pairing this upgrade with a high-flow performance air filter to accommodate the increased airflow demands. Backed by a 12-month/12,000-mile parts warranty.
