This spark plug was designed
before the transistor radio
Tempest introduces a spark
plug for the 21st century
“Old school” competitive plugs
use a screw, spring, carbon pile
stack up known to suffer from
resistance value instability.
Result: Potential misfires, wasted
fuel and engine roughness.
We are a proud partner
with EAA on their legacy
fleet of aircraft.
See you at
Tempest monolithic engineered
resistors are warranted to remain at
or near manufacturing specs
throughout the normal service life of
the spark plug. The center electrode
and resistor are fused together as
one piece to eliminate flashover and
resistance buildup problems.
Result: Smooth running engines.
