FOXWELL ST100 Automotive Smoke Machine Leak Detector, High-Density Smoke

• ONE TOOL, MULTIPLE SYSTEMS: Covers EVAP, turbo, intake, exhaust, vacuum, and fuel systems with dual-pressure modes (0.5–17 psi). EVAP-safe low pressure, with the included EVAP adapter ready to use out of the box. Find leaks behind Check Engine lights, failed emissions, rough idle, poor gas mileage, and more.
• BUILT-IN AIR PUMP: No external compressor required. Just connect to your 12V battery and start testing. Portable and self-contained, perfect for home garages, driveways, or mobile mechanics.
• DUAL MODE (AIR + SMOKE): Air Mode pre-checks for leaks without wasting oil and purges residual smoke after testing. Switch to Smoke Mode to pinpoint the exact leak location. Saves time, oil, and guesswork.
• ULTRA-FAST, DENSE SMOKE & TIGHT SEALS: Dense smoke appears in seconds. Real testing shows the full process — from unboxing to finding the leak — takes as little as 7 minutes. Included adapters form tight seals, keeping smoke inside the system, not your setup.
• COMPACT, LIGHTWEIGHT & AFFORDABLE: Small enough to fit in your toolbox, yet powerful enough for professional use. Runs on simple mineral/baby oil for extremely low operating cost, and helps avoid expensive shop diagnostic fees. Works on most 12V gas/diesel cars, SUVs, light trucks, motorcycles, ATVs, boats, and snowmobiles — ideal for DIYers and mechanics.
• TRUSTED FOXWELL QUALITY & SUSTAINABLE DESIGN: Backed by FOXWELL’s 17 years of R&D and regularly tested on real US vehicles. Built with GRS-certified recycled materials for a lower environmental impact. A reliable, professional-grade tool you can count on.
