NGK LFR5A-11 (6376) V-Power Nickel Spark Plug
TheNGK LFR5A-11 (stock number 6376) is a genuine V-Power nickel alloy spark plug built for the modern Hyundai / Kia Theta II and Nu four-cylinder engine family. It is the OE-equivalent service part for the Hyundai Sonata (NF / YF, incl. Sonata 8), Lingxiang (领翔), New Santa Fe, ix35, and the Kia K5, Sorento, Sportage and Cadenza 2.0 / 2.4 L gasoline engines. Sold here as a factory-sealed 4-pack — exactly the quantity a four-cylinder Hyundai / Kia needs for one complete service.
The critical distinguishing feature of this LFR5A-11 nickel alloy spark plug is its 26.5 mm long-reach thread. This is NOT the common 19 mm plug used on older small-displacement Hyundais. The long-reach design is required by the deeper cylinder-head spark-plug boss on the Theta II / Nu engines; using a standard 19 mm plug leaves the threads exposed in the combustion chamber, causes overheating, thread damage and possible piston contact. Always confirm the reach before ordering.
Other specifications follow the proven V-Power recipe: M14 × 1.25 thread, 16 mm hex, gasket seat, a V-cut nickel centre electrode on a copper core that concentrates the spark at the electrode edge, an integrated 5 kΩ resistor for ignition-noise suppression, and a factory pre-set gap of 1.1 mm (0.043 in) — the"-11"suffix. Heat range is 5, calibrated for the everyday 2.0 / 2.4 L naturally aspirated and GDI applications common across the Sonata / ix35 / Santa Fe range.
It directly cross-references the Hyundai / Kia OE number 18841-11051 (also used across the Kia HMC parts bin), and is interchangeable with the Denso equivalent and NGK's own platinum / iridium upgrade paths (LFR5AP-11 / LFR5AIX-11). Beyond Hyundai-Kia, the same NGK 6376 spark plug fits selected Nissan (Sentra 2.5L QR25DE) and Suzuki (SX4 1.6 VVT) applications.
Sold as a 4-piece set in factory boxes; ideal for repair shops and DIY owners doing a full set change. Bulk / wholesale tray packing is available for distributors and chain service centres.

FAQ
Q1: Is NGK 6376 the same as LFR5A-11?
Yes.LFR5A-11 is the part number; 6376 is the NGK stock number — the same V-Power nickel plug.
Q2: What does the"L"mean in LFR5A-11?
L = long reach, 26.5 mm thread length. This is critical — do not replace it with a standard 19 mm plug (such as BPR6ES or BKR5EYA series).
