High-performance Denso K16TT spark plugs featuring dual-electrode (twin tip) design for reliable ignition, extended service life, and improved combustion efficiency—sold as a set of four.

Description

NICKEL TT

High ignitability nickel plug (impact of thin diameter on both sides of electrode)

A new nickel alloy achieves thin diameter on both sides of the electrode, improving combustion by boosting flame development

Boosting flying sparks and ignitability

Thin center electrode (1.5mm)
Double Needle structure (a first with nickel)
Utilizes nickel alloy featuring new materials

Reasons why the Ni-TT plug can cover for other Nickel plugs

The Ni-TT plug can cover for other standard plugs thanks to its better ignitability (flame kernel spreads easily).
