Universal Compatibility Whether you own a high-end diagnostic smoke machine or a portable DIY unit, this adapter is compatible with ALL automotive smoke testers. The standard inlet nozzle fits most smoke machine delivery hoses, turning your existing tool into a versatile powerhouse for modern engines.
New Larger Design for Heavy-Duty Use Many standard cones are too small for modern performance intakes and large-bore exhausts. Our New Larger Size handles the big jobs:
-
Maximum Diameter: 3.25 inches (82mm)
-
Minimum Diameter: 1 inch (26mm)
-
Perfect for Intake Boots, Air Filter Boxes, Exhaust Tips, and Intercooler Piping.
Professional Grade Durability Built to withstand the harsh environment of a professional shop, this cone is made from premium, automotive-grade rubber. It is resistant to high temperatures and chemical degradation from oils and fuels, ensuring it won’t warp or lose its seal over time.
Effortless “Plug-and-Play” Operation Forget complicated clamps or specialized adapters. To use:
-
Insert the tapered cone into the diagnostic site (intake or exhaust).
-
Attach your smoke machine hose to the cone’s inlet.
-
Inject smoke and watch for leaks. The tapered design uses friction to create a high-pressure seal, allowing you to find even the smallest pinhole leaks deep within the system.
