NGK PLZKAR6A-11 (5118) Double Platinum Spark Plug
TheNGK PLZKAR6A-11 (stock number 5118) is a premium NGK double platinum spark plug from the Laser Platinum range, the original-equipment service part for the Renault Fluence (2.0 L), Koleos (2.0 L) and Latitude (2.0 L) petrol engines, plus the Nissan Frontier 2.5 L. In several markets this plug is also listed under the variant designation PLZKAR6A-11B — it is the same plug, cross-listed under an NGK / OE numbering variant. Confirm fitment by the OE number stamped on the old plug.
What makes this a double platinum (PL) plug is that both electrodes carry platinum: a 1.0 mm fine-wire platinum centre electrode laser-welded to a copper core, and a laser-welded platinum pad on the ground electrode. Because both precious-metal surfaces resist erosion, the gap holds its factory setting far longer than a nickel plug, delivering a service life of roughly 70,000–90,000 miles (110,000–145,000 km) on the engines that specify it. The fine platinum tip also lowers firing voltage, which keeps ignition coils cool and lean-mixture ignition reliable.
Specifications follow the Renault M4R / Nissan platform layout: M14 × 1.25 thread, 26.5 mm (1.04") long reach,14 mm (9/16") hex, flat gasket seat, integrated 5 kΩ resistor, and a factory pre-set gap of 1.1 mm (0.043 in) — the"-11"suffix. Heat range is 6. The 26.5 mm reach is critical: these Renault / Nissan aluminium heads use a deep spark-plug boss, and a shorter 19 mm plug will not seal correctly.
It cross-references the Renault OE numbers 22401-EA015 / 22 40 1EA 015,77 01 065 085 / 22 40 123 31R, and the Nissan 22401-CK81 / 22401-CK81B / 22401-CK87B family. Beyond Renault, the same NGK 5118 spark plug is OE-equivalent for a range of Nissan (Frontier, Xterra, Sentra, Versa) and Suzuki applications that share the platform.
Sold individually in factory-sealed boxes, or in 4-packs for the four-cylinder service interval. Distributors, Renault / Nissan specialist workshops and online sellers value PLZKAR6A-11 (5118) as a stable, long-life premium SKU with OE-grade reliability and lower customer returns than nickel equivalents.
