MK8 Golf R PCV System Retrofit Kit for EA888.3 platform vehicles

Available as a DIY Kit or Professionally Fitted at KMS Motorsport HQ (Wigan)

Upgrade your Golf R, GTI, S3 or Cupra with the superior PCV system from the MK8 Golf R using our complete KMS Motorsport retrofit kit. Designed for enthusiasts and tuners alike, this kit enhances engine performance, reliability, and crankcase ventilation — using only Genuine VAG Group parts for OE-level quality.

✅ Why Upgrade?

The MK8 Golf R PCV system features key design improvements over the MK7 version, making it ideal for both standard and tuned cars:

• Better Crankcase Ventilation
  Reduces internal crankcase pressure, especially under boost – ideal for tuned engines or track use.
• Reduced Oil Blow-By
  Helps prevent oil vapour entering the intake system, reducing carbon build-up on intake valves.
• Improved Reliability
  Less prone to failure compared to the original MK7 PCV system, particularly in high-performance applications.
• Boost Leak Prevention
  More robust under boost – no more annoying PCV-related boost leaks on tuned setups.
