Overview
Not a multi-plug set, this NGK traditional plug comes alone with a copper core, a resistor and an insulator made of pure alumina silicate. Corrugated ribs and cold rolled threads protect against flashover and head damage.
It is a conventional plug designed to reduce fouling with a longer insulator nose. Buy one per cylinder, since only one is in the pack, and check the thread against your engine.
Who it's for
Vehicles whose manual calls for this standard plug and its copper core. Owners wanting a single-order set, or a longer-life tip, will need another listing.
Pros and cons
- Copper core dissipates heat
- Triple gasket seal
- Cold rolled threads
- Sold as a single plug
- Gap size not listed
- Thread given only as RM
Performance notes
The longer insulator nose reduces fouling and the copper core pulls heat from the tip. The resistor limits electrical interference, and the triple gasket seal stops combustion leakage past the shell.
