🔧 OEMTOOLS 25352 Ramp Style Spark Plug Gap Gauge - Spark Plug Gapping Tool for Precise Adjustment and Measurement - Spark Plug Gauge Gap Tool for Improved Engine Performance - Plug Gapping Tool with Easy-to-Use Features Review

The first use it began to bend, the metal is super soft, do not buy! Another seller sells one in zinc alloy and looks chrome plated. I bought it and got my money back for this one.

I have a calibrated caliper that I have used to verify the accuracy of this caliber. He is not accurate in his measurements. The only reason I measured it was because I noticed the metal wasn't exactly level at the measuring service. That struck me as suspicious.

I just tried it because I saw it on You Tube and thought it looks easy to use. However, I have noticed that NGK does not recommend using this tool to use precious metal spark plugs with newer fine wire electrodes ([.] It seems that it can easily damage a platinum or iridium fine wire tip when trying to adjust the gap , or even damage it if you try to measure the gap. If you're using regular OEM connectors then this is probably fine - otherwise I'd use a wire gap tool.
