Review on Thexton THE404 Spark Tester: Enhancing 🔥 Ignition System Performance with Reliable Spark Testing by Mark Turner

Likes: The device is unique and basically unique in its performance and operation Dislikes: I work in the automotive industry and have used it in field conditions for many years Somewhat disappointing is the fact that the Body and body construction is thinner and less robust compared to the previous design. Conclusion = It still performs and performs as advertised, so don't let the redesign put you off this tester - it's still unique and the best resource for stress testing ignition coil performance. Unsurpassed!
