An alternative to conventional feeler gauges for measuring spark plug electrode gaps
Halfords Spark Plug Gauge Metric
Does what it says.
A good value tool but not very robust.
The sides bent the first time I used it.

Probably the best little tool I have! It's perfect, does the measuring and adjusting without any effort at all.

Ok for gap checking
This set of feeler gauges can be used to alter the gap as well as measuring the gap.
Well the item is made cheaply and is not u[p to the job of altering the gaps.
So its rubbish at that.
It measures Ok and the sizes are clearly labelled on each blade.

Not too good
This particular product was not as it was shown on website. All others were fine and I personally love halfords.
