2017-2019 L5P Duramax Throttle Valve Upgrade by VSE Engineering

Upgrade your factory leak prone L5P / L5D Throttle Valve

 

The factory connection point where the factory throttle valve meets the "Y" bridge is the most probable place for a boost leak due to the plastic ring design. Ours uses a 1 piece high temp oring mounted into a grove cut into the assembly for a leak proof fit. We include a barbed design on the throttle valve connection to match up with your aftermarket cold side intercooler boot to prevent it from backing off during high boost/heat scenarios.

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

 

Features:

• No throttle blade (race use only)


• 3 x 1/8" NPT connections for connecting Boost, Water/Methanol, Nitrous, or Boost leakdown equipment


• Leak proof oring connection


• Barbed machining for maximum grip on lower intercooler boot


• 1/2" longer than the factory throttle valve for maximum clearance and fit

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