The first thing you want to do is find a car with a turbo. Installing a blow off valve in a car without a turbo doesn't really work.
Find the blow off valve in the car. You are going to replace it with a new one.
Loosen the hose clamps that hold the hoses to the factory unit.
The hose leading back to the intake needs to be blocked. The hose after the turbo is the one we are attaching to the blow off valve. The smallest hose attaches to the top of the blow off valve.
Install the new blow off valve. Then put everything back together. Close the hood and take it for a test drive. You should feel the grumble of the engine. The car should perform better. To really test out the new blow off valve, I recommend testing it on a racing track. That's it, you are done.Want to learn how to install a blow-off valve? Then look no further.
