Review on 🔌 CTA Tools 3238 Spark Plug Gap Gauge with 9 Wires by Richard Summerall

Suitable tool for checking/adjusting the spark plug gap. While it doesn't have a full range of gauges, it does cover most "normal" gaps. I rated it 4 out of 5 stars based on the price as I feel the price is a bit high for what you are buying. The product seems sturdy enough to do its job. I've used it on two sets of forks so far and all is good. With this tool you can successfully adjust iridium and platinum spark plugs without damage as long as they do not come in contact with the center electrode or the insulator. This tool adjusts the ground electrode on most connectors, which is the correct way to adjust connector spacing. DO NOT step between the ground and center electrodes as you will DAMAGE the connector.
