Time for a tune-up? This 8-pack of NGK Iridium spark plugs is a great deal for keeping several vehicles running smoothly. They're brand new, unused, and come in their original packaging – genuine NGK plugs, a top brand trusted by mechanics worldwide. The part number is LFR5AIX-11, which is also the interchange, OEM, and superseded part number (sometimes listed as 4469). These are iridium plugs, which offer better performance and longevity compared to standard copper or platinum plugs – they fire more reliably, can improve fuel efficiency, and last longer. This set of 8 plugs is perfect if you have multiple vehicles that use this plug, or if you just want to have spares on hand. They fit various Hyundai, Nissan, Infiniti, and Yamaha models (always double-check your specific vehicle's requirements, though!). NGK backs these with a lifetime manufacturer warranty, which is pretty awesome and shows they stand behind their quality. There's no UPC, but the part number is clear. Whether you're a DIYer doing your own maintenance, a professional mechanic stocking up, or just someone who wants the best for their engine, upgrading to iridium plugs from NGK is a smart move. They can help with cold starts, smooth idling, and overall engine performance. Keep your rides firing on all cylinders with this quality 8-pack!
