Hiya all,

I am from Singapore and the weather is on the average of 28 degree
celsius. What ratings of NGK plugs will be better for my FXR180???


NGK BR9???-

ES Types

NGK standard spark plugs with copper cored centre electrodes for wide
heat range. Copper's superior heat conductivity dissipates the heat
of combustion away from the firing end, preventing hot spots that can
lead to pre-ignition. Copper cored electrodes also mean that longer
insulator noses can be used to protect against fouling.

EG Types

These plugs feature a smaller diameter centre electrode tip made of
conventional nickel alloy. The smaller diameter centre electrode
means the voltage required to produce a spark is reduced. However as
the tip is made of conventional nickel alloy the service life is
reduced and these plugs are best used in applications where plugs are
frequently changed.

EV Types

These plugs have a smaller diameter centre electrode (1.0mm) than the
EG types which is made of Gold Palladium Alloy. The smaller diameter
centre electrode means the required voltage is even lower.

EVX Types

These plugs have an even smaller centre electrode (0.8mm) than the V
types, which is made of platinum. This combined with a taper cut
ground electrode has a lower required voltage than the V types. This
results in better ignitability along with improved starting, idle
stability and anti-fouling performance.

EGV Types

These plugs have a centre electrode of precious metal similar to the
EV range. In addition, the insulator nose is an improved design to
allow better gas flow around the firing end. The ground electrode is
shorter and stronger, making the EGV range ideal for the most severe
racing applications.
