NGK 4 Spark Plugs + Igniton Coil for Holden Astra AH 2.0L 4Cyl Premium Quality

We Provide Genuine NGK Products Solution Just For Your Vehicle!

The essential function of the ignition coil is the delivery of high voltage, which jumps between the centre and ground electrode of the spark plug within a cylinder, generating the ignition spark.

In the ignition process, the NGK ignition coil plays a vital role in providing reliable ignition and allowing for the smooth and efficient operation of the engine compared to cheaper alternatives.

Due to excessive heat generated by an internal combustion engine, radiant heat surrounding an ignition lead spark plug tube can be in excess of 500 degrees!

As a result some vehicle applications require heat-shield sleeve protection for their ignition lead spark plug boots or tubes.

NGK Ignition lead spark plug boots and tubes have been designed to pair pefectly with NGK plugs allowing for perfect and harmonious performance in your engine.

Each ignition lead is fitted with a positive locking, corrosion resistant stainless steel terminal end for a tight fit and maximum resistance to vibration and separation.

NGK spark plugs in conjunction with NGK leads and coil will allow for your ignition to run at it's best possible potential, giving you a safer and smoother driving experience.
