Upgrade the throttle-valve connection on a 2017-2019 L5P/L5D Duramax competition application. VSE combines a machined O-ring seal with a barbed boot connection to help maintain a secure seal between the Y-bridge and aftermarket cold-side charge piping.

• Blade-free intake passage.
• Three 1/8-inch NPT accessory ports.
• High-temperature O-ring at the Y-bridge connection.
• Body extends 1/2 inch beyond the factory valve for additional clearance.

Application notes: Race applications only; custom tuning is required. Requires an aftermarket cold-side intercooler boot and does not connect to the factory boot. Charge piping is sold separately.
