Tri-Power Iridium Spark plug

The Modern Car Choice

Tri-Power iridium Spark plugs are manufactured and tested to the highest OEM approved quality standards. Iridium has better wear resistance and service yield due to the higher melting point and offers a greater resilience to oxidation compared to standard or platinum plugs. The use of precious metals decreases the electrode size which in turn, increases the service life.
