Its iridium construction supports better engine idle stability, quicker acceleration, and smooth overall engine performance, making it a dependable choice for engines that call for this plug's specification. The electrode uses a laser-welded design that raises the plug's melting point, helping it hold up under sustained heat cycles without breaking down prematurely. This construction also contributes to reliable cold starting, so the engine fires consistently even in cooler conditions. AC Delco applies its current spark plug technology to the 41-110 to deliver consistent ignition performance and dependable startups over the plug's service life. It is designed as a direct equivalent to the NGK IZTR5B11 and Donovan 203054 plugs, so it can be used as a replacement wherever those part numbers are specified. Buyers replacing worn plugs or servicing an engine that calls for the 41-110, IZTR5B11, or 203054 spark plug can install this part without modification.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e AC Delco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 41-110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 707773443538\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Iridium Spark Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrode Material:\u003c\/strong\u003e Iridium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Laser-welded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e Donovan 203054, NGK IZTR5B11\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDonovan 203054\u003c\/li\u003e\n\u003cli\u003eNGK IZTR5B11\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the AC Delco 41-110 spark plug made of?\u003c\/strong\u003e The AC Delco 41-110 uses an iridium electrode with a laser-welded construction, which raises its melting point and supports long-term durability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 41-110 cross-reference to an NGK plug?\u003c\/strong\u003e Yes, the AC Delco 41-110 is a direct cross-reference to the NGK IZTR5B11 spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a Donovan equivalent to this AC Delco plug?\u003c\/strong\u003e Donovan 203054 is the cross-reference number for the AC Delco 41-110 spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 41-110 spark plug weigh?\u003c\/strong\u003e This spark plug weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 41-110 help with cold starting?\u003c\/strong\u003e Reliable cold starting is one of the listed benefits of the AC Delco 41-110, thanks to its iridium construction.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat performance benefits does the iridium construction provide?\u003c\/strong\u003e On the AC Delco 41-110, iridium construction is said to improve engine idle stability, support quicker acceleration, and contribute to smooth overall engine performance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the AC Delco 41-110 a genuine AC Delco part?\u003c\/strong\u003e Yes, the 41-110 is manufactured and sold under the AC Delco brand, not a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 41-110 replace an NGK IZTR5B11 plug directly?\u003c\/strong\u003e Since the AC Delco 41-110 cross-references to the NGK IZTR5B11, it can be installed as a replacement wherever that NGK number is specified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat construction method is used on the electrode?\u003c\/strong\u003e The AC Delco 41-110 electrode is laser-welded, a construction method used to increase its melting point and reliability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this spark plug?\u003c\/strong\u003e Ordering the AC Delco 41-110 gets you a single iridium spark plug of that part number.\u003c\/p\u003e","brand":"AC Delco","offers":[{"title":"Default Title","offer_id":49027424649435,"sku":"ACD-41-110","price":12.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/ACD-41-110__86737.1747363840.500.750.jpg?v=1785163227","url":"https:\/\/www.goodvibesmarina.com\/products\/ac-delco-41-110-iridium-spark-plug-cross-reference-ngk-iztr5b11","provider":"Good Vibes Marina","version":"1.0","type":"link"}
