By not needing to change the other 7 plugs, I've saved $50 on parts and 2 hours on labor.

One of my techs at my auto repair shop has one and loved it, so I had to get one for myself.

Quick easy diagnostics to find where to start. If you don’t have one your spending a lot of time chasing running issues...

This worked better than I could have imagined in detecting a miss on a car I was working on, a coil on plug design. It was crystal clear immediately.

I had been swapping parts but could not identify the faulty unit(s). In about 3 minutes it identified two weak coil packs, others checked good. Fun and easy to use.

Couldn't believe that a small handheld analyzer like this one could read and display so many parameters of the ignition status. I only wish i had this useful yet compact tool years ago.

When to use:

Suspected spark plug damage

Engine misfires

Determining fuel efficiency

Engine misfires, broken spark plug wires, etc

Function:

Measures the period from the moment a spark is initiated up to the point when it is extinguished.

Measures the period between the ignition coil being energized and the spark being generated.

Measures from when the primary coil current first begins to increase to when it stops increasing.

Measures the voltage of the spark plug.

How to use:

Place sensor on the spark plug you want to measure. If the burn time is abnormally long or short burn, this may indicate some problem in the ignition module, spark plug, fuel mixture, cylinder compression, etc.

Dwell angles are specified for a particular engine and
RPM. If this reading is off from your engine’s spec, the dwell angle may need to be adjusted.

Use these measurements in combination with others to determine whether your engine is performing at optimal levels.
