Iridium Spark Plugs for MERCEDES BENZ S Class Sedan S350 W221 3.5L – TPX027

TRI-POWER IRIDIUM SPARK PLUGS

All Tri Power plugs are Iridium, get the performance and specs without the price.

The TRI-POWER ultra-fine wire electrode takes less voltage to fire, increasing the life time of spark plug and other components (coils) and ensuring reliable ignition. Benefits of the TRI-POWER Ultra fine wire spark: Improved ignitability Better idle stability Easier starts in cold weather Lower emissions Reduced stress on other ignition system components (coils).

All TRI-POWER Iridium spark plugs are manufactured with an iridium alloy centre electrode and platinum ground for exceptional longevity and reliability.

During manufacture all TRI-POWER components are tested for bending resistance, hot leakage, impact strength, resistor durability, thermal cycling and leakage, torque strength, vibration and weld flash.

TRI-POWER ultra-fine wire spark plugs are great upgrades for old vehicles with lower energy ignition systems.
