When I first came across the Toolwiz Spark Plug Gap Tool, I was immediately impressed by its thoughtful design and practicality. This product is not just another tool; it’s a versatile companion for anyone who deals with spark plugs. Whether you’re a professional mechanic or a DIY enthusiast, having a reliable tool to accurately gap spark plugs can significantly enhance the performance of your engine. The Toolwiz Spark Plug Gap Tool, with its 32 blade steel feeler gauge, is designed to meet the needs of users who want precision and efficiency.

One of the standout features of this tool is its universal fitment. It’s compatible with most standard spark plugs, specifically the 10mm, 12mm, 14mm, and 16mm sizes. This means that whether you’re working on a car, motorcycle, or a small engine, you’re likely to find this tool applicable. However, it’s important to note that it does not work with 18mm thread plugs or long/short reach plugs.
