This ISSPRO tachometer provides accurate, real time RPM information that many factory gauges either don’t include or don’t display with enough precision. With a clear view of engine speed, you can shift at the right time, keep the engine operating in its most efficient power range, and reduce unnecessary strain on internal components. The added awareness helps prevent over revving, avoids engine lugging under load, and promotes smoother operation, better fuel efficiency, and long term engine reliability in all driving conditions.

IMPORTANT NOTES:

• 92 And Above Option gauge is sold with a bracket, wiring harness, and R8913 filter which allows you tie the tach into the 92 and above Dodge ECM
