Note: The spark plug shown in the main listing image is for illustration purposes only, you'll receive the correct spark plugs and quantity as stated in the listing title.

 

LPG Laserline

LPG LaserLine spark plugs are dual precious metal spark plugs specifically developed for gas-fuelled engines. The combustion of gas is different from the combustion of petrol and, therefore requires spark plugs that are specially adapted for these conditions. The gas-air mixtures are more difficult to ignite as more ignition voltage is required and the risk of failure of the ignition coils increases. NGK Laserline spark plugs come with a lifetime of up to 60,000 km, clearly outperforming “normal” spark plugs.

 

High-Tech Electrodes

LPG Laserline spark plugs feature an iridium tipped centre electrode and a ground electrode that contains a platinum chip. The tip of iridium is attached in a specially developed laser welding process patented by NGK. The advantage: These precious metals are resistant to the unfavourable conditions in gas powered engines. The spark gap remains virtually unchanged throughout the entire service life.

 

Individual Spark Gap

A copper core in the ground electrode of every LPG Laserline spark plug improves the temperature discharge, which helps to regulate the higher temperatures in gas powered engines. A specially developed insulator protects these spark plugs from fouling when being used on regular petrol.

 

Heat Shield for the Metal Shell

A special alloy coating covers the shell 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.

Less Stress on the Ignition Coils

Studies conducted by NGK show that the required ignition voltage in gas powered engines increases by as much as 7,000 volts – an acid test for the ignition coils. The iridium centre electrode of Laserline spark plugs is only 0.6 mm in diameter, this provides a counter measure since it requires a lower ignition voltage, in-turn reducing stress on the coils. The shape of the electrode also facilitates optimum advance of the flame front.

Authenticity

We (Driven 2 Automotive) only supply 100% genuine NGK spark plugs. In fact, we play a major active role in fighting back fakes by producing a series of website blog articles dedicated on showing you how to spot the dodgy ones!

In a bid to help everyone understand the severity of how accurate some copies can be these days, we provide detailed, side-by-side comparison photos of genuine spark plugs placed directly next to counterfeits that we've discovered online, providing help to all those who need it.

Trust genuine, trust us! Simply type 'How to spot fake Iridium IX spark plugs' in a search engine and we'll sure be near the top of the results.

 


Vehicle Compatibility

  • Please search for NGK's spark plug finder on a search engine to verify plug fitment.

  • If there's a compatibility chart added to this listing, please use it as a guide only and verify fitment with NGK's part finder tool.



Installation

WARNING - DO NOT USE COPPER GREASE (AKA COPPER SLIP, ANTI-SEIZE, THREAD COMPOUND) ON MODERN SPARK PLUG THREADS!

  • Using such lubricants can result in over-torqued values with a torque-wrench by up to 20 percent! Possibly causing major damage.
  • Virtually all modern spark plugs feature a special zinc-chromate shell plating which provides corrosion resistance to the elements.
  • Spark plugs should be tightened down with a dry thread only.
  • On spark plugs that feature a crush-able base gasket washer, be prepared for tightening to feel odd (gets harder) at the last stage.
  • Follow the instructions on the box that show you to finger tighten first and then rotate the amount shown afterwards with a wrench.
  • The only time anti-seize compound should be used is on vintage spark plugs that use a non-coated, usually black surface.


 

Need a Different Quantity?

  • Other quantities are available in our shop. Simply search 1x, 2x, 3x etc before the spark plug part number.
  • Wholesale discount orders are available - please contact us.
