AutoLine Pro Smoke Machines Ranked

A two-mode machine with a gauge and flow meter, for owners of turbocharged cars who also need EVAP testing. The listing says little about the kit or air source.

The cheapest machine here that covers both EVAP and boost leaks. It suits DIY owners who can do without a gauge.

The gauge version of the HyperSmoke, for DIY owners who want EVAP-safe testing and a way to confirm a repair held. It costs about $26 more than the base model.

A low-cost machine with both an EVAP mode and a higher-pressure mode, for DIY owners chasing a check-engine light. Pick the Pro version if you want a gauge.

The cheapest EVAP-safe machine here, for an occasional DIY leak hunt. Like the Model 01, it has one low pressure and no gauge.

A plain EVAP-safe machine at a low price, for DIY owners with an EVAP code. It is not the tool for boost leaks.

The Shop Series with its own air motor, for owners without a compressor. It suits vacuum and intake leaks; the maker does not list an EVAP-safe pressure.

A simple smoke generator for a garage that already has compressed air. Without built-in air or a gauge, it is the bare-bones way to smoke-test.

A cordless smoke machine for mobile techs and anyone tired of battery clamps. The flow meter and lifetime warranty help justify the price.
