NGK Iridium IX Spark Plugs (4) for 1994-2001 Integra 1.8 B18B1 One Step Colder

The NGK ZFR6FIX-11 Iridium IX Spark Plug Set includes four plugs for 1994–2001 Acura Integra models equipped with the non-VTEC B18B1 1.8L engine.

With an NGK heat range of 6, the ZFR6FIX-11 is one heat range colder than the commonly used heat-range-5 plug for the B18B1. A colder spark plug may be appropriate for certain modified, forced-induction, or higher-load engine combinations when specified by the engine builder or tuner.

NGK Iridium IX spark plugs use a fine-wire iridium center electrode to produce a concentrated, consistent spark while requiring less ignition voltage than a conventional electrode design. The projected-tip configuration and tapered-cut ground electrode help improve ignitability and reduce fouling.

Installation Note

Although the plugs are supplied with a preset gap, always inspect and verify the gap before installation. Spark-plug heat range and gap requirements may change based on boost pressure, ignition system, fuel type, engine modifications, and tuner recommendations.

Consult your engine builder or tuner before selecting a colder spark plug for a modified application.
