The Air Hold Adapter Kit air fitting/spark plug by PROFORM is a precision pneumatic coupling component designed for engine builders, tuners, and professional mechanics working on high-performance fuel systems and diagnostic applications. This adapter kit connects air supply lines to spark plug-threaded ports, enabling controlled pressure delivery for carburetor adjustments and fuel pressure testing.
The air fitting/spark plug adapter allows shop air and diagnostic equipment to attach directly to the engine without the need for additional fabrication or adapter stacking. PROFORM's engineered design features a precision-ground thread profile compatible with standard spark plug holes, paired with a low-profile air coupling that accepts industry-standard quick-disconnect fittings.
Professional engine builders and fuel system technicians benefit from this adapter's ability to ensure leak-free, repeatable connections without thread damage or cross-threading risk. Its compact size and lightweight construction help minimize engine bay clutter and installation interference, making it a valuable tool for various diagnostic applications.
