Dedicated Blow Off Valve JRspec for Mini Peugeot 1.6 Turbo N14 N18

The JR.Spec Blow Off kit is a fully aluminium, piston-type valve with no diaphragm, eliminating common OEM failures while retaining ECU control thanks to the included solenoid and wiring harness. The valve operates on a pressure/vacuum principle, and the spring is interchangeable—allowing a stiffer spring to be fitted for higher boost. It’s a solution for modified cars as well as stock vehicles driven in warmer climates, and for anyone wanting a more pronounced valve sound.

Electronically controlled DV valves used on MINI/BMW/Peugeot 1.6 Turbo engines (N14/N18, THP) are known for diaphragm failure and brittle plastic retaining rings, which can cause leaks, boost loss, and—at worst—risk of turbo damage from plastic debris.

Product features:

• Piston design, no diaphragm—significantly higher durability than OEM
• CNC-machined aluminium housing
• Retains OEM ECU control
• Interchangeable spring—can be matched to different boost levels
• Improved boost response and more stable boost holding
