Why are TAKUMI spark plugs superior?

By Li Chenyu / hcfire360 November

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 continuously sparking.
• It provides superior thermal conductivity and prevents overheating.
• It resists thermal shock and provides superior mechanical strength.

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 durability.
Special nickel alloy ensures superior heat resistance and durability.
