Nitrous Outlet Spark Plug Reading Tools

3.2 out of 5 stars 5 Customer Reviews

Besides having a reliably tuned nitrous system, properly reading your spark plugs is one of the keys to fast performance. Nitrous Outlet spark plug readers enable you to read your spark plugs for air/fuel, timing, plug temperature, and detonation. They're designed to magnify and illuminate the hard-to-read area on the top portion of the spark plugs. Each reader tool comes with a handy storage case.
