    Key Features<\/h4>\n
      \n
    1. \n
      Easy-Read Gauge<\/h5>\n

      PSI and bar scales with three color zones that indicate good or bad status, so you can judge the exhaust system quickly.<\/p>\n<\/li>\n

    2. \n
      Shockproof Rubber Cover<\/h5>\n

      A protective rubber boot gives a comfortable grip and helps prevent damage if the gauge is dropped.<\/p>\n<\/li>\n

    3. \n
      Long, Heat-Resistant Hose<\/h5>\n

      The 6 ft thickened silicone hose resists wear and heat and lets you watch the gauge from the driver’s seat.<\/p>\n<\/li>\n

    4. \n
      Two Thread Sizes<\/h5>\n

      M12 and M18 threaded adapters connect the gauge to the exhaust port.<\/p>\n<\/li>\n

          Care<\/span><\/h5>\n
            \n
          • The gauge is checked and calibrated before shipping. If the pointer does not rest at 0, it may have been knocked in transit; remove the cover and reset the pointer to 0. This does not affect test results.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/section>\n<\/div>","protected":false},"excerpt":{"rendered":"
