Description

SPARK PLUG

MIA's Description

The Denso 4002 is a U-Groove spark plug designed to improve fuel efficiency and throttle response. Its U-shaped groove in the ground electrode allows for less flame dissipation and a larger flame front, promoting more complete combustion. This plug features machine-rolled threads to prevent seizing and a purified alumina powder insulator for strength and thermal conductivity.
