KNOCK GAUGE for Turbo Buick or Turbo Trans Am

This knock gauge has a 2″ face, will fit any of our gauge holders and will work on Turbo Buicks or Turbo Trans Ams.

It features a series of 10 LED lights; 3 green, 4 amber, and 2 red which measure the knocks, and a green activation light.

The severity of detonation is displayed in three different colors. The green light is the least severe and red denotes the most severe detonation. Because of the obvious colors as they light up, it is easy to understand and note detonation.

The LED lights remain lit for 5 seconds before they automatically reset to normal.

Each gauge comes with directions and is a three-wire hook up.

NOTE - You will need to supply 18-gauge wire to install it in your car.
