NGK Traditional Spark Plug is manufactured to enhance the performance of
the vehicle. It is constructed from durable material that is corrosion
and abrasion resistant. The Spark plug insulators are made of 99 percent
pure alumina silicate, allowing for longer insulator noses for reduced
fouling. This Spark plug features a triple gasket sealing process that
eliminates fuel leakage. It also includes a solid copper core that
provides superior heat dissipation and conductivity. This Spark plug has
resistor that is produced with a glass and carbon mixture, which is
fired to ensure superior performance and durability. It has corrugated
ribs that prevent flash over and cold rolled threads to inhibit damage
to the cylinder head.
The NGK BPR9ES plugs are 3 heat range colder then the stock spark plugs. These cooler plugs have additional detonation resistance, and are more prone to fouling as compared with the stock spark plugs.
