Heard of this product mentioned on the Yank VW scene. Probably not the same quality as Forge but it does include some interesting extra's!.

Product dedicated especially to this model of car.

With this system you can fit an external discharge valve without encountering the known and awkward problems that this car creates in fitting a normal external discharge valve.

Many will have attempted to install an external discharge valve on this car and many will have thought that everything was ok for a while.

Shortly after however they will have realised (just like we did) that something was not working properly.

The car fails to exceed 4200 rpm and by turning the engine off and on again, the defect disappears but then reappears after a certain amount of time, but much worse, triggering the “Check Engine” LED and sometimes also the anti-skid LED.

All this occurs when driving in the town traffic, because if the car is driven constantly sporty, the defect could still appear but very rarely.

The blame for all this is down to the external discharge valve, whatever the brand.

Even our valves triggered such problems, but then after months of experiments and tests on various cars, we found the solution to the problem (but it’s obviously a secret)

Now (as is customary of our company) we are able to provide you with a hi-tech product with the guarantee and safety of a high air discharge sound, totally free from problems.

The product is supplied with detailed instructions and photographs so that anyone can install the product quite easily.
