PQY’s gapping tool combines a lightweight matte-anodized aluminum body with a full set of manganese-steel feeler blades so you can measure and adjust electrode spacing precisely. It’s intended for standard reach spark plugs (10mm, 12mm, 14mm, 16mm threads) and includes a brass blade for electronic ignition systems; it does not fit 18mm-thread, long-reach, or short-reach specialty plugs.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use the PQY gap tool to adjust a plug quickly?\u003c\/h3\u003e\n\u003cp\u003ePlace the spark plug into the tool’s saddle, insert the chosen feeler blade between the electrodes, then tighten the knob until the electrode contacts the blade. Back off or reinsert a different thickness if the fit isn’t exact, and recheck after releasing to allow for any spring-back.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSelect the blade matching your target gap (reads from 0.04mm to 0.88mm).\u003c\/li\u003e\n  \u003cli\u003eSeat the plug in the tool and insert blade flush against the electrode.\u003c\/li\u003e\n  \u003cli\u003eScrew the adjustment knob slowly until the electrode meets the blade.\u003c\/li\u003e\n  \u003cli\u003eIf electrode springs back, use a slightly thinner blade and re-measure.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat gap sizes and blade types are included with this gauge?\u003c\/h3\u003e\n\u003cp\u003eThe kit contains 32 individual manganese-steel feeler blades ranging from 0.0015\" (0.04mm) to 0.035\" (0.88mm), plus one 0.010\" (0.25mm) brass blade for use with electronic ignition systems.

If your target gap is, for example, 0.44mm, it’s practical to set the tool to a marginally smaller thickness (such as 0.42mm) so the electrode returns to the intended spacing when released.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eEstimate spring-back and choose a slightly thinner feeler blade.\u003c\/li\u003e\n  \u003cli\u003eRe-check gap after releasing the tool to confirm final measurement.\u003c\/li\u003e\n  \u003cli\u003eRepeat adjustments incrementally rather than forcing a single large change.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: The PQY Universal Spark Plug Gap Gapping Tool is aimed at DIY mechanics, professional technicians, motorcycle riders, and small-engine hobbyists who need an accurate, portable solution for setting spark plug gaps. If you work with standard-thread plugs and want a durable aluminum tool plus a full feeler-blade set for precise measurements, this kit provides a practical, workshop-ready option. If you use 18mm-thread or specialty reach plugs, look for a tool designed for those sizes instead.\u003c\/p\u003e\n\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this PQY tool fit 18mm-thread spark plugs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No, it’s not compatible with 18mm-thread plugs.
