Spark Plug Analyzer Tool
If your VW isn’t running quite right — hesitating off the line, missing under load, or just feeling a little sluggish — it could be your spark plugs. Don’t play the guessing game. This spark plug analyzer gives you a clear answer in minutes, so you can get back to enjoying the drive. This handy tool lets you test the health of your spark plugs before they ruin your weekend cruise. It’s built with dual test holes, so you can check two plugs side by side and instantly compare spark strength.
With an adjustable RPM range from 500-6000, it mimics real engine conditions so you know how your plugs will perform when it matters. Before checking the spark using the Spark Plug Analyzer, visually inspect the spark plug for any signs of wear or damage.
Things to look for include carbon deposits that indicate excessive fuel consumption or a rich fuel mixture, oil fouling that suggests an oil leak or worn piston rings if the tip is wet with oil, rust or corrosion buildup that can hinder proper function, or worn-out or eroded electrodes that can affect spark intensity.
