IGNITION LEADS

STRUCTURE

The fibreglass strand core is covered by a layer of ferrite magnetic material wound with variable- pitched stainless steel wire. The outer jacket offers excellent insulation and heat resistance made from either;

  1. NGK’s silicone insulation – 260°C heat rating
  2. NGK’s EPDM rubber compound (Ethylene Propylene Diene Monomer) - 180°C heat rating
  3. Polyvinyl Chloride - 100°C heat rating

NGK have selected the most appropriate insulating material to specifically suit each particular vehicle application.

RFI (Radio Frequency Interference)
The unique structure of NGK Ignition leads ensures that they provide uniform resistance, outstanding electrical conductivity and produce the impedance necessary to suppress RFI throughout the entire frequency spectrum. RFI noise generated by ignition systems can interfere with computer controls and on-board electronic systems in late model vehicles. When used in combination with resistor spark plugs, NGK Ignition Leads provide exceptional noise suppression without negatively affecting engine performance.

FEATURES

Electromagnetic Interference (EMI) suppression
Adoption of stainless steel wire and ferrite magnetic core produces the impedance necessary to suppress EMI without comprising sparking performance.

Stable Resistance
The resistance of solid carbon-core Ignition Leads tends to increase with time, however the resistance of NGK wire wound Ignition Leads remains virtually unchanged.

Excellent Conductivity
The lower resistance (2-8 kΩ/m compared to 16 kΩ/m for common leads) offers superior conductivity.

Superior Heat Resistance
The highest quality silicone insulation provides a wide operating temperature range. Unlike other materials it is capable of superior performance under extreme conditions (-50⁰C to 250⁰C).

IDEAL FOR LPG

LPG increases the required voltage to form a spark and raises the risk of cross-fire between Ignition Leads which can result in backfire and damage to the air box. Poorly made Ignition Leads do not offer the required resistance, impedance and insulating properties to minimise cross-fire. NGK Ignition Leads with their variable pitched stainless steel winding, ferrite magnetic core and quality insulation jackets are proven to be the best choice for LPG applications.
