Windshield A-Pillar SINGLE Gauge Pod
Product ID: 1530-Buick
Windshield A-Pillar SINGLE Gauge Pod
This windshield A-pillar single gauge holder is made by the same company that does the popular console twin gauge holder we offer.

The holder comes painted grey to match the interior of the 1986-1987 Grand National. However, it will fit any 1978-1987 Regal, and can be painted to match any interior color using spray paint safe for plastic. It will house any 2-1/16″ or 2-1/8″ gauges.

Once you mount the pod with your gauge on the A-pillar post (between the door and windshield), your gauge will be easy to see while driving.

The holder is easy to install and attaches to the windshield pillar post by double-sided tape that is provided with holder. It’s not necessary to cut any holes.

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

Thermostat Housing
Product ID: ENG105
Thermostat Housing

This reproduction thermostat housing is made from a heat-treated stainless that will stay like new for many years. If you need to change the thermostat, it’s a welcomed improvement.

Comes with a new O-ring on the housing

Price: $36.00

160 Thermostat
Product ID: ENG106
160 Thermostat
1986-1987 Turbo Regal special 160-degree thermostat required by some of the aftermarket computer chips. This thermostat can be used with your stock computer chip enabling your car to run cooler. By lowering the engine temperature, you can gain more power. This will also cut down on the number of times that annoying electric fan will kick on as you shut your car off, since your engine will operate at a cooler temperature.

Because of its unique size, the 160-degree thermostat is NOT found in any auto parts stores. Most parts stores only carry the stock one. No gasket is required, and the original O-ring can be reused.

NOTE: This thermostat can effect emissions, so if local laws have emissions tests, it is not recommended.
Price: $16.95
