Brand-new, all stainless steel GM OEM black oxide finished clamp (size 048; 3-1/2" max. diameter) for stock 1986-1987 Buick Grand National, Turbo Regal, and **1989 Turbo Trans Am.
THESE ARE GENUINE "MADE IN USA" OEM CLAMPS, NOT cheap IMPORTED AFTERMARKET CLAMPS with plated steel parts as sold elsewhere.
There are four of these clamps used per vehicle on a 1986-1987 Buick Grand National or Turbo Regal; one for air cleaner to intake elbow, one for intake elbow to mass airflow sensor, one for mass airflow sensor to intake air duct, and one for intake air duct to turbo inlet (bell) adaptor.
**1989 Turbo Trans Ams use five of these clamps per vehicle; one for air cleaner to intake elbow, one for intake elbow to mass airflow sensor, one for mass airflow sensor to intake air duct, one for intake air duct to connecting hose, and one from the connecting hose to the turbo inlet (bell) adaptor.
These black oxide finished, all stainless steel (band, housing, and screw) OEM clamps CANNOT BE DUPLICATED by painting or powdercoating imported aftermarket clamps.
BLACK OXIDE IS NOT A COATING - IT IS A CHEMICAL PROCESS.
IT WILL NOT CHIP, peel, lift, or crack.
