PLEASE NOTE: RECOMMENDED FOR LPG CONVERTED CARS ONLY!
LPG GAS REQUIRES A HIGHER VOLTAGE AND HOTTER COMBUSTION TO USE CORRECTLY
Before "Laserline" plugs came alone the only option was to change to a platinum plug with a higher heat range and a closer gap. This can cause high levels of corrosion on the electrodes and housing, and an increased strain on the ignition coils
NGK Laserline Iridium plugs have a special alloy coating to prevent corrosion and protect it from the higher heat involved from the combustion of LPG
They also use a fine wire Iridium center electrode (0.6mm) to counteract the extra voltage needed on standard plugs.
1. High-tech electrodes
LPG LaserLine spark plugs have an iridium-tipped centre electrode and a shell electrode with a platinum chip. These precious metal chips are attached in a specially developed laser welding process patented by NGK. The advantage: the precious metals are resistant to the unfavorable conditions in gas operated engines. The spark gap remains virtually the same throughout the entire performance range.
2. Individual spark gap
The ideal gap between the center electrode and shell electrode of every LPG LaserLine type is preset for gas operated engines. Manual adjustment is no longer necessary.
3. Optimum thermal properties
A copper core in the shell electrode of every LPG LaserLine spark plug improves the temperature discharge, which helps to regulate the higher temperatures in gas operated engines. Design properties protect these spark plugs even better against fouling.
4. Heat shield for the housing
A special alloy coating covers the housing of every LPG LaserLine spark plug, protecting it from the higher temperatures and the increased risk of corrosion. No other manufacturer currently offers a similar coating.
5. Relief for the ignition coils
Studies conducted by NGK show that the required ignition voltage in gas operated engines increases by as much as 7,000 volts – an acid test for the ignition coils. The iridium center electrode of an LPG LaserLine spark plug, only 0.6 mm in diameter, provides a counter measure, since it requires very low ignition voltage. The shape of the electrode also facilitates optimum advance of the flame front.
