(Complete blow off valve kit including high flow turbo outlet tube)

SSP is proud to offer the Spulen Blow Off Valve kit for the new 1.8T & 2.0T engines. From the factory, the 1.8T & 2.0T engines found in the MK7 GTI, Golf, Golf R, Audi A3, and S3 do not have mass air flow sensors (MAF). This gives the ability to run a conventional vent to atmosphere blow off valve rather than a recirculating diverter valve. 

 

Features:

High flow turbo outlet Tube

Factory diverter valve block off cup

Authentic HKS SQV4 blow off valve

Audible vent to atmosphere noise

Pre-installed HKS SQV4

No check engine light or fault codes.

 

The Spulen Blow Off Valve Kit is not just a simple replacement valve. In order to properly fit a blow off valve to these vehicles, several components were needed. Each component is outlined below.

 

Block Off Cup

Starting at the turbo, a custom block off cup was designed to block off the factory diverter valve. The cup installs on the end of the factory diverter valve and blocks off the factory diverter valve passage. This insures no pressurized air will leak from the factory location. With the cup in place, the factory diverter valve remains in position and plugged in so no fault codes are triggered in the car’s computer (ECU).

 

Turbo Outlet Tube

With the factory diverter valve blocked off, a location was needed to install the new blow off valve. A turbo outlet pipe was constructed for the blow off valve to attach to. Constructed out of 2.25” aluminum tubing, the turbo outlet tube not only provides a mounting location for the new blow off valve, it also eliminates the restrictive turbo outlet tube. 

 

Blow Off Valve

Several blow off valves were tested and ultimately the HKS Super Sequential 4 (SQV4) was chosen. The SQV4 was chosen because of its superior response time, ability to hold high boost, and its reliability. The SQV4 also provides a unique sound favored by many enthusiasts. 

 

Boost Tap

Since the SQV4 requires a vacuum source to operate, the USP boost tap was selected to provide a solid and reliable vacuum. The USP boost tap installs between the intake manifold and pressure sensor and provides a dedicated vacuum source for the SQV4. Since many users may already have a boost tap installed, the Blow Off Valve Kit is available without the USP boost tap.  

  • Authentic HKS SQV4 blow off valve
  • Eliminates failure prone factory diverter valve
  • Perfect for "chipped" cars
