MK8 PCV Retrofit Kit for MK7 / MK7.5 Golf GTI R (MQB Breather Upgrade)

Upgrade your MQB MK7 / MK7.5 with the improved MK8 PCV system using this complete retrofit kit.

The factory PCV system on earlier MQB vehicles is a known weak point — especially on tuned or higher boost setups. This retrofit utilises the revised MK8 design to improve crankcase ventilation and reliability.

Why upgrade to this PCV?

• Improved crankcase ventilation over MK7 design

• Helps manage increased crankcase pressure on tuned vehicles

• Reduces risk of boost leaks through the PCV system

• More stable operation under higher load / boost

Why this kit?

• Complete retrofit solution — no guesswork

• Includes all required components for installation (except bung if not using Venturi)

• Retrofit for MK7 / MK7.5 MQB

• Retains OEM drivability

• MK7 Golf GTI
