Many spark plug suppliers will tell you that one spark plug will fit a number of vehicles. What they don’t tell you is that this “one size fits all” approach compromises the performance of the vehicle. This old-school type of thinking disregards advancements in modern engine evolution and can compromise precision engine output, reliability, and fuel efficiency.
Engine manufacturers spend many years researching and developing a new engine blueprint. During this complex process, every engine component, including the spark plug, is engineered and tailored to perfectly match the make and model to ensure optimum performance and durability.
When Spark Plugs are commonised, important attributes are ignored that can have a big effect on performance and longevity. Some key side effects include:
- Too cold – Spark Plug is prone to carbon fouling
- Too hot – Spark Plug is prone to detonation/pinging – that can escalate to overheating damage of the engine
Centre Electrode Projection
- Too long – High risk of mechanical interference with pistons or valves
- Too short – Reduces ignitability, performance and fuel efficiency
Number of ground electrodes
- Replacing the multi-ground OE spark plug design with a single ground electrode Spark Plug, can cause unstable idle for wasted spark ignition systems
Ground electrode design
- Adverse effect to ignitability, performance and fuel efficiency
Double Fine Electrode (DFE) design
- By replacing a non-DFE OE spark plug design with a DFE Spark Plug, can create issues stemming from excessive ground electrode projection and inefficient heat dissipation.
