Spark plug tester, Inline Spark tester, Spark Tool HT Lead Ignition Spark Plug Testers Accuspark Set of 4

Good to have a set of four as you can see all 4 cylinders at the same time.Easy to use, remove spark plug lead from plug, push on tester, re connect lead and repeat for other cylinders. Turn over/start engine and check that each plug is sparking.Great value for money and a useful diagnostic tool for petrol engines

Great bit of kit

The media could not be loaded. Work Great and are well made, easily visible as you can see in the video, Good price ! needed as checking a spark with high voltage coils such as this Rs Turbo can seriously damage the Ecu so these are a must.

Good product. Nice and clear to see and use to tune my 1979 mini.

A very handy tool, helps out with the ignition problems 👍

need to know if you have a spark on an old car? these lil babies will tell you...Edit: they worked great... twice, on third use checking for a misfire on an MG three of them came apart on removing

Brilliant piece of kit

I bought them to fault find on my petrol lawnmower. They light up very clearly trying to start the mower. Exactly what I needed.
