UPR Spark Plug Gapping Tool 10mm 12mm 14mm


      UPR's Spark Plug Gapping Tool with Built-in Feeler Gauges Designed to save time and give you much more precise gaps. This is what engine builders you as they are telling you how critical your plug gap is. Our new plug gapper will allow you to gap plugs must faster and maintain gap accuracy between all your plugs.

The days of banging your plugs against table corners or the side of the tool box to close the gap risking porcelain fatigue and chasing spark leakage.
