Breather By-Pass Kit
Product ID: BR1580-Buick
Breather By-Pass Kit
This kit consists of a passenger’s side breather with a chrome-plated cap and a rubber plug to close off the turbo inlet bell. Many of these turbo cars are getting oil into the intercooler which, in turn, causes the hose connections to loosen up on the inlet pipe. If this problem is allowed to continue, it will gum up the throttle body and cause your turbo to run rough. This breather eliminates that pipe and the danger of oil going through your system. The metal top isn’t affected by the heat of the turbo. Nothing else to buy. You can easily return your car to stock.

NOTE: This breather by-pass kit may not be legal for sale or use on pollution controlled vehicles in California and other states.
Price: $19.95
