Practical and easy to use device to check and adjust spark plug gap. Made from some strange alloy and would prefer stainless steel, but that probably would hike up the price.

Inexpensive and convenient means of checking plug gaps. Made of some strange alloy, and would prefer stainless steel, bit that would raise the cost I suppose.

We all remember the ''''''''Does exactly what it says in the tin'''''''' advert and this little Spark Plug Gap Tool does ''''''''exactly what it says on the tin'''''''' it''''''''s a simple, totally effective piece of equipment anyone fitting replacement plugs, or those just carrying out routine maintenance checks, really need to include in their tool kit. I thoroughly recommend it.

This is an easy tool to use. it dose not damage the plugs electrode during the adjustments. It however could do with a way of fitting it to a key ring so you can have it at hand all of the time without having to search for it in your tool box.
