Product Details

NGK is a long-standing OE supplier with broad coverage across domestic and import vehicles, and the Iridium IX line focuses on durable ignition components built to original equipment standards. Part number 93893 uses an iridium fine-wire center electrode to support consistent firing, while the copper core helps manage heat transfer during normal engine operation. This combination makes it a practical choice for performance-minded maintenance on vehicles that call for a 0.028, 0.030, or 0.032 inch gap depending on application.

This part cross-references NGK 93893 for the same application.

What It Helps Address

• Rough idle caused by worn spark plugs
