Best Automotive Smoke Machines Under $100 Ranked

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.

A low-cost digital-gauge machine for occasional DIY use. Its run-time limit makes it a poor fit for a busy shop.

A budget machine with a gauge and flow meter for vacuum and intake leaks.

A budget gauge-and-flow-meter machine for vacuum and intake leaks. EVAP testing needs a separate regulator.

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 mid-price gauge-equipped machine for vacuum and intake leaks. Solary does not publish its output pressure, so check it before testing an EVAP system.

A cheap higher-pressure machine for intake and vacuum leaks. Its output is too high for EVAP testing without a regulator.
