Tool Review: Performance Tool W127C Spark Plug Gauge

Performance Tool makes different spark plug gauges of varying quality.  The W127C (also marketed as a Wilmar spark plug gauge) wire gauge is not great, but better than at least one other PT gauge.  I'd give it 2 out of 5 stars.

If you're interested in this gauge, Amazon.com sells it for $1.52.  For that price, it's not a bad buy, as long as you have another gauge to check its accuracy.
