NGK builds it with a 0.6 mm fine-wire iridium center and a platinum pad on the ground electrode so both wear surfaces last. That's why these plugs go about 100,000 miles on Honda's maintenance schedule while a nickel plug is done in a third of that. They come pre-gapped at 1.1 mm. Don't touch the gap. Prying on a fine-wire iridium tip is how a new plug dies on the bench.\u003c\/p\u003e\n\u003cp\u003eThread is 14 mm x 1.25 with a 19 mm reach and a gasket seat, a 5\/8 in (16 mm) hex, heat range 6, and a solid terminal.

Work on a cold engine. Pull one coil, swap one plug, torque it to NGK's 18 to 21.6 lb-ft spec, and move to the next hole so nothing falls into an open tube. Start every plug by hand. Cross-threading an aluminum head turns a 30 minute job into a bad weekend.\u003c\/p\u003e\n\u003cp\u003eWhile the coils are out, check each boot for tears and look at the spring contacts. A torn boot will misfire right after a plug job and get the new plugs blamed. If your Civic is past 150k and still on original coils, plenty of owners do coils and plugs in one shot. One box, four plugs, and the ignition side is done until well into the next decade of ownership.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003cp\u003eThis set fits the 2006-2011 Civic DX, LX, LX-S, EX, and EX-L with the 1.8L R18.
