AUTOOL SPT101 Spark Plug Tester

The AUTOOL SPT101 is a bench tester for comparing spark plug performance under simulated engine-speed conditions. Two plugs can be tested at the same time, making it easy to spot weak or inconsistent spark behaviour before a plug is installed in the engine.

I recently took my car to a Machanic, fault code misfire on 2 cylinders,so they recommend i replace spark plugs and fuel injector clean or replacement, so after the consult they give me a quote of $ 2200 ,for 16 spark plugs,fuel injector cleaning, labor.. so I saw this product on Facebook, bought it for like 50 60 dollars, and found i only had 3 spark plugs fault,so very happy it only cost me for the product and my time. I highly recommend checking other sources before consulting a Machanic.
Thanks Discount tool.
