1998 Buick Riviera Supercharged
It is by far the most complete kit on the market for these cars,
and it uses the highest quality pure silicone hose.
This kit replaces all the vacuum lines under the hood as well as the long radiator overflow hose. This is a pre-cut kit and it includes two small vacuum "T"s. It's very important to have leak free hoses and connections on the supercharged 3.8. Now that they are old, the factory hoses often leak under boost causing incorrect pressure signals to reach the map sensor, fuel pressure regulator, and the supercharger's bypass solenoid and bypass actuator. If your supercharged Riviera is a little low on power, or has higher than normal fuel consumption or emissions this kit will probably help.
