Bring a little life to your 2.7 L3B turbo Cadillac CT4/CT4-V with our ZZPerformance bypass valve spacer. This CNC spacer installs in between your factory bypass valve and the turbo and vents the air partially to atmosphere, giving you a classic turbo PSHH that we all love without the drawbacks of a full vent to atmosphere blow off valve. More importantly, this bypass valve spacer will not set any check engine lights.
Simply remove your stock bypass valve, and install our ZZP unit in between that and the turbo with the included stainless bolts. The turbo side is O-ringed to ensure a proper, leak free, sealing surface. Anodized black finish.
Fits: 2020-2026 Cadillac CT4 2.7T. Also fits 2023-Present 2.7T Chevrolet Colorado, 2023-Present 2.7T GMC Canyon, 2019-Present Chevrolet Silverado 2.7T, and 2019-Present GMC Sierra 2.7T.
Designed and machined in house at ZZPerformance in Wyoming, MI.
