Features 5

  • GAP SPARK PLUGS TO YOUR VEHICLES SPECIFICATIONS: Every engine has different specified sizes for spark plug gaps generally speaking, more powerful engines require small gaps, less powerful engines require large gaps; this tool lets you measure spark plug gaps and adjust spark plugs to the proper gap size
  • SPARK PLUG REPAIR AND INSTALL TOOL: Spark plugs are sold in common gap sizes, so usually they do not need to be gapped, but for custom engines and for repairing older plugs, resizing your spark plug gap is often required
  • SPARK PLUG DIAGNOSTIC TOOL: If you know youve got an issue with a spark plug, checking that its properly gapped can be a good starting point for any repair; Make sure you clean the plug first
  • PRECISION GAPPING TOOL: Gapping tool is useful for making slight adjustments to your spark plug gap; Remember, your bottom electrode is fragile, so you want to make small adjustments to avoid bending it back and forth

Description

Test and properly gap the spark plugs for any car, truck, SUV, motorcycle, boat, lawnmower, golf cart, chainsaw, or anything else that uses a combustion motor for power. Improperly gapped spark plugs can be a common reason for older plugs to struggle or fail. Sometimes the solution is simply to regap the old plug, while other times you’ll need to reinstall a brand new, properly gapped plug to fix the engine issue. Remember, most modern cars use just a few spark plug gaps sizes, and you can usually buy spark plugs pre-gapped to these specifications. However, if you’re conscientious, it might be worth measuring the gaps on these pre-gapped plugs before installing them, just to be safe. Remember, before you perform any serious engine repair, including replacing or re-gapping spark plugs, first disconnect your battery lead to protect you from shock. Spark plug repair, replacement, and re-gapping are all relatively simple procedures, though some engines are certainly easier to work on than others. If you’re not comfortable doing the work on your own, professional mechanics do this sort of work every day. FULL SPECIFICATIONS: - Everything you need to gap your spark plugs to 6 common gap sizes - Measure: . 025” (. 64mm), . 03” (. 76mm), . 034” (. 86mm), . 035” (. 89mm), . 04” (1. 02mm), and . 045” (1. 14mm) - Measure and adjust with this one small tool

helps check the correct gap
Since I've had this, found NEW Plugs that weren't gaped correctly.

Rusts incredibly easily
This tool is not made of good steel. I had it for one week and there is rust all over it because it got wet one time. (I'm not talking sitting in a bucket of water. I mean it got rained on a little bit because it happened to be sitting under a nail hole in my shed roof.) Now it is worthless as a gap gauge because the rust affects the accuracy. I know this is partially my fault, but I have never seen so much rust on a tool after getting wet one time. ... show more

This product is garbage.
Received the item twice and both shipments the item was damaged. A closer look indicated a manufactured piece of garbage. What a disgrace.
