Q1. What is the function of a spark plug?
A It serves as a lighter to ignite the air/fuel mixture.
It operates under extreme conditions.
Q2 Why are GOMEX spark plugs superior?
A They are designed to extract maximum performance from the engine
throughout its range.
1.It is an "ultra wide heat range" spark plug. It has a center
electrode with copper deeply inserted in the tip to quickly
dissipate large amounts of heat. This makes for a spark plug with
an "ultra wide heat range" that resists both overheating and
fouling.When the thermal characteristics of spark plugs with and
without copper cores are compared, spark plugs with copper cores
prove to be superior in heat and fouling resistance and provide a
wider thermal operating range.
2. This spark plug incorporates an insulator made of
state-of-the-art high-alumina ceramics.
• It has superior insulation at high temperatures and offers
• It provides superior thermal conductivity and prevents
• It resists thermal shock and provides superior mechanical
3. It has solid construction to ensure reliable gas-tightness.
Special hot crimping process to make sure superior gas-tightness
and strong construction.
4. The electrode tip made of special nickel alloy ensures superior
Special nickel alloy ensures superior heat resistance and
Q3 What is the heat rating of a spark plug?
A spark plug must dissipate the heat produced by the combustion
gases. The heat rating is a measure of the amount of heat
It is essential to use a spark plug with a heat rating that matches
a specific engine and its condition of use.
When a wrong heat rating is selected,
When the heat rating is too high,
The spark plug temperature remains too low and causes deposits to
build up on the firing end; the deposits provide an electrical
leakage path that possibly cause misfire.
When the heat rating is too low,
The spark plug temperature rises too high and induces abnormal
combustion (pre-ignition); this leads to melting of the spark plug
electrodes that could cause problems such as piston damage.
Q4 How long will a spark plug last?
A Even when a spark plug is correctly used, periodic replacement is
required as it is a consumable item.
Examples of problems caused by excessively long periods of use:
Worn-out electrodes will have difficulty in sparking.
Deposits accumulated on the firing end may induce abnormal
combustion, causing problems that include melting of the electrodes
or damaging engine.
These spark plugs require replacement.
It must be noted that these phenomena may also be caused by
inadequate engine servicing (fuel systems and ignition system) and
incorrect spark plug selection.
Q5 In addition to correct heat rating, what other precautions
should be taken during installation of spark plugs?
A Ensure the spark plug has the correct thread reach.
The engine will not operate properly without the proper thread
If a spark plug with the wrong thread length is erroneously used,
the piston or valve could strike it and damage the engine.
Moreover, there is also the concern that the electrode could
overheat and melt.
