Aluminum Turbo Blow Off Valve for VW Audi 1.8T 2.7T

Upgrading your turbo system starts here. This aluminum blow off valve replaces the fragile factory plastic component on your engine. It protects your turbocharger by routing excess pressure straight back into the intake pipe instead of venting it out. You gain instant throttle response while preventing dangerous compressor stall. The hardened exterior withstands intense under-hood temperatures without warping or corroding.

Benefits & Tips

Select the spring rating that matches your power goals. The yellow coil arrives pre-installed with a 15–23 PSI setup ideal for street driving. Upgrade to blue or red coils once you increase fuel mapping or force. Wipe your mounting gasket surface before bolting it on. A flat, debris-free seal guarantees steady boost flow and eliminates hissing sounds.
