Spark plug viewing tools provide an accurate means to precisely read spark plug conditions, insulation, and electrodes. They include a deeply shrouded lens that eliminates unwanted peripheral glare, and a shatter-resistant plastic lens. spark plug holders are helpful accessories for a mechanic or do-it-yourself gearhead when performing a tune-up or under hood maintenance.
