out of 10
This 12V diagnostic tool uses an integrated air pump and thick smoke to quickly identify hidden leaks in vehicle intake and EVAP systems. It is an essential asset for home mechanics and shop technicians looking to eliminate tedious guesswork during engine diagnostics.

I recently put the 12V Automotive Smoke Machine to the test to see if it could actually simplify the frustrating process of tracking down intermittent vacuum leaks. By injecting smoke directly into the vehicle's intake and exhaust systems, I was able to visualize leaks that would have otherwise taken hours of manual inspection to locate.
