A fouled or worn plug shows up as a misfire, hard starting, or a cylinder that won't pull its weight. Fresh plugs give your ignition a clean, hot spark to work with.\u003c\/p\u003e\n\u003ch3\u003eWhy You Need This\u003c\/h3\u003e\n\u003cp\u003eThe D8HA is the correct heat range for these engines: hot enough to burn off deposits, not so hot it pre-ignites. Run a plug that's too cold and it fouls with carbon; too hot and it can pre-ignite. The copper-core construction gives a reliable spark and a long service life.\u003c\/p\u003e\n\u003cp\u003eThe CB175 family is a parallel twin, so you need two plugs, one per cylinder. When you're chasing a carb jetting issue, grab a few extra and read the porcelain tip color to dial in the mixture.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable class=\"spec-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePlug Type\u003c\/td\u003e\n\u003ctd\u003eNGK D8HA (copper core, 18 mm hex, 12 mm thread)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpark Plug Gap\u003c\/td\u003e\n\u003ctd\u003e0.024–0.028\" (0.6–0.7 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReplaces OEM\u003c\/td\u003e\n\u003ctd\u003e98066-58714, 98066-58717, 98066-58723, 98066-58727\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFits Models\u003c\/td\u003e\n\u003ctd\u003eCB175 \/ CL175 (1968–1973), SL175 (1970–1972)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold As\u003c\/td\u003e\n\u003ctd\u003eSold individually (two needed per bike)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"NGK Spark Plugs","offers":[{"title":"Default Title","offer_id":41532950478906,"sku":"D8HA","price":3.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2726\/2594\/files\/Screenshot2026-07-16121937.png?v=1784230148","url":"https:\/\/shopbertsmegamall.com\/products\/st-ngk-d8ha","provider":"Berts Mega Mall","version":"1.0","type":"link"}
