Review on 🧰 A & E Hand Tools 4450A E-Z Grip Spark Plug Gap Gauge - Easy and Reliable Orange Tool by Ron Patel

If my old car sat in wet weather for a long time, I might have had problems driving home from a quick errand. Wires, coils, distributor cap and spark plugs replaced. Apply electrical lubricant. However, there was a small problem. I set the gaps to 1.1mm because that's what they turn out to be if you buy them with a gap for this model. I decided to reset them to 1.0mm, the minimum specified. I found that the sensor I had was giving erroneous results. At first glance, the gap may seem too narrow. If I tried again, it might seem too loose. The loop of wire was so small I couldn't tell if I was tilting the sensor. I ordered the EZ Grip. The "bottle opener" hole for prying off the ground electrode looked great, but I didn't need it. By plugging the plug into an extension socket, I've gotten an assembly with a lot more bulk than a single plug. When I tapped with a large enough wrench, there was enough momentum to close the gap in small increments until it was right. I capped the thin end of the gauge and moved it up until I felt resistance. If the 1.0 mark was in the center of the electrode, I assumed the gap was 1.0. I wanted to test the sensor, but without a vise, I didn't know how to hold the caliper in a specific spot on the sensor. and hold it at right angles to the meter and move my eyes to a position where I can read the display. I made the decision later. I fixed the caliper at gaps in 0.1mm increments and watched how far it slides through the gauge. I found the gauge to be 0.05mm thicker from 0.6mm to 1.8mm. Reading the mark in the center of the electrode increases the error because when the end of the center electrode is flat, the front face meets the resistor. The standard diameter of the center electrode is 2.5mm, so the reading at the center is about 0.04mm smaller. In total, this is 0.09 mm less. The caliber isn't that accurate, so I call it 0.1mm. Now I know I need to look for a reading that is 0.1mm smaller than the desired distance. When I set my clearances, I read the gauge at 1.0, but I set it at 1.1. When I started narrowing these gaps, the EZ Grip showed them to be 1.1mm. That is, they were actually 1.2. This might well explain my "weak spark" issues. I no longer trust a sensor with tiny wire loops. I'm sure my caliper was correct because I checked it with feeler gauges. If I had originally used feelers, I could have avoided this problem. Well, the EZ Grip is quicker to use and I like the "bottle opener". I just have to remember that my reading is 0.1mm lower when I read it in the center of the electrode. I can use a dipstick to check.
