Purpose and Application Features

The NGK 90288 DILKAR7M8 iridium spark plug set is designed for gasoline engines of modern cars, where high-precision and stable ignition of the fuel-air mixture is required. The plugs belong to the professional Laser Iridium line, which ensures an extended service life, efficient operation over a wide temperature range, and a stable spark even under increased loads. This set of four plugs is suitable for servicing four-cylinder engines equipped with original plugs of the same catalog number.

The plugs are designed for long-term use, support smooth idling, confident engine start, and optimal fuel consumption. NGK products are widely used both in factory settings and in subsequent vehicle servicing.
