AT5K Spark Plug Resistance Tester

***MORE ARRIVING MID APRIL***

The Tempest AT5K quickly and accurately checks spark plug resistors and quickly displays the results.

Note: The AT5K only checks resistance values. It does not replace, nor is it a substitute for, other tests required to determine a spark plug’s condition.

CHECKING SPARK PLUG RESISTANCE IS IMPORTANT:

Excessive resistance causes:

  • Hard starting.
  • Skipping, missing, excessive fuel consumption and pollution.
  • Roughness in turbocharged engines.
  • Roughness during lean of peak operations.
  • Roughness at high altitudes.
  • Spark plug fouling.
  • Engine oil contamination from excessive carbon and unburned fuel entering the crankcase.
  • Unnecessary electrical stress on ignition leads, contact points, capacitors and magnetos.
  • Costly, unnecessary spark plug maintenance.

AT5K means: “At 5000 Ohms” change that plug!
Install Tempest spark plugs with monolithic solid state resistors!


CHECK RESISTANCE PRIOR TO INSTALLATION:

New spark plugs without monolithic resistors may drift out of range even before being entered into service.
