4. PQY Universal Spark Plug Gap Tool with 32 Blades Steel Feeler Gauge for Most 10mm 12mm 14mm 16mm Spark Plugs Red

When I came across the PQY Universal Spark Plug Gap Tool, I couldn’t help but feel a sense of excitement. This tool is specifically designed for automotive enthusiasts and DIY mechanics who want to ensure their vehicles run at optimal performance. With its compatibility for most standard spark plugs, including 10mm, 12mm, 14mm, and 16mm sizes, it provides versatility that many users will find indispensable. However, it’s essential to note that it doesn’t support 18mm thread plugs, so a quick check before purchase is advisable.

The build quality of this tool is impressive. Made from high-quality aluminum with a matte texture, it feels sturdy in my hands and is engineered for ease of use. I appreciate how the design allows me to adjust the spark plug gap quickly and accurately.

The inclusion of a 0.010-inch (0.25mm) brass blade specifically for electronic ignitions is a thoughtful touch that expands its usability. Whether I am working on a classic car or a modern vehicle, this feature ensures I have what I need at my fingertips.

However, it’s crucial to keep in mind that this tool is not compatible with long reach or short reach spark plugs, so checking the size beforehand is essential. This attention to detail in fitment makes it clear that PQY has designed this tool with the user’s needs in mind.
