Laser Platinum
NGK Laser Platinum� spark plugs are the masters of ignition performance in addition to a longer service life. Dual platinum surfaces on the centre and ground electrodes ensure a much slow wear rate compared to standard plugs. Idle stability is improved along with superior anti fouling, improved fuel efficiency and lower emissions.By utilizing the highest amount of platinum content in the industry, NGK has created an extremely long-life, high performance spark plug. The laser welded platinum tip on the center electrode works in harmony with the ground electrodes platinum pad or tip (depending on part number) to achieve such results.
The ground electrode is also taper cut, in simple terms this is done to reduce as much obstruction as possible to the flame as it starts to burn from the initial spark. This allows for a more complete, efficient burn which in-turn increases MPG.
Features
- Laser welded Platinum tip on the centre electrode for improved durability and electrical conductivity
- Laser welded Platinum pad or tip (depending on part number) on the ground electrode provides a longer service life
- Trivalent metal plating provides superior anti-corrosion and anti-seizing properties
- Service life of up to 90,000 miles
- Improved cold start performance
- Taper-cut ground electrode reduces 'quenching' (helps the flame to expand with minimum amount of obstruction)
- Improved idle and smoother acceleration
- Better fuel economy and lowers exhaust emissions
- Fantastic quality as you'd come to expect from NGK
- Original Equipment (OE) approved design
IMPORTANT - WARNING
** DO NOT USE ANTI-SEIZE LUBRICANT SUCH AS COPPER SLIP ON THE THREADS WHEN FITTING THESE SPARK PLUGS **
Shown below is an over torqued spark plug that sheered due to user installation error. NGK states that incorrect torque values are responsible for up to 90% of all spark plug warranty claims. Incorrect torque can also result in poor engine performance, read below:
- Under-torqued spark plugs do not make full contact with the cylinder head which reduces the plug�s ability to transfer heat out of the combustion chamber, this results in elevated combustion temperatures and as such can cause pre-ignition and detonation. These two conditions can lead to engine damage. Evidence of under-torqueing can be seen via the crush washer gasket not being as thin as expected (unless it's a tapered type plug).
- Over-torqued spark plugs can cause stress to the metal shell, leading to thread breakage (sheer) as shown in the image below. Over tightening can also compromise the plug�s internal gas seal or even cause a hairline fracture to the insulator. Evidence of over torque is easy to spot, for example hex swelling is visible and usually the crush washer is thinner than expected. If the thread has sheered the breakage will look similar to the spark plug image shown below.
- It's advisable to use a good quality, calibration certified torque-wrench. Users should always wind down their torque-wrench to the minimum scale setting and never all the way down after each use. A fully loaded torque wrench left in storage for a long period of time can cause a 'set' in the spring and weaken it. The result can be an inaccurate torque reading.
- Care must also be taken to ensure the spark plug socket is not slanted at an angle as this can put pressure on the ceramic insulator causing it to crack.
Installation Notes
- Compressed air should be used to clean the area around the existing spark plugs before removal. Torqueing the new spark plugs up against any form of debris and build-up in the threads may prevent the plugs from making full contact with the cylinder head, even if a torque wrench indicates otherwise. This can cause poor heat dissipation which leads to higher cylinder temperatures, possibly causing pre-ignition or detonation.
- On vehicles where positioning a torque wrench is difficult or impossible, finger tighten the plugs first and then follow the rotational guide shown on the NGK packaging with a standard wrench.
- If the engine design means it's difficult to fit or remove spark plugs (or even see them), the plug wrench may tilt off-axis or slip. If the socket slips on the plugs hex and the inside wall of it strikes the ribbing on the plug's insulator, or its terminal, the insulator may break.
- Some new spark plugs feature a washer gasket that is designed to be crushed during the last stages of tightening. This will feel different to tightening any normal bolt or nut up.
- Only use a spark plug gapping tool which pulls on the ground electrodes neck to adjust the gap on precious metal spark plugs.
- The only time anti-seize compound should be used is on vintage spark plugs that do not feature a specialised coating.
