Hyundai Kia Spark Plug 27410-37100 PFR5N11 High Efficiency Ignition KLP

KLP spark plugs (OEM numbers 27410-37100/PFR5N11) can directly replace modern Hyundai/Kia factory parts; widely compatible and batch-insensitive. Core function: efficient ignition; iridium electrode ensures stable ignition, complete combustion, and reduced deposits. Fits many 2000+ Hyundai and Kia models such as Elantra, Sonata, Cerato, etc. Replacing noticeably improves cold-start difficulty, acceleration hesitation, and reduces fuel consumption. If idle jitter or sudden fuel consumption rise occurs, it likely means spark plugs are aging and should be replaced promptly.
