This bundle pairs one UF549-style ignition coil with four iridium spark plugs engineered for higher conductivity, thermal resistance, and longer service life than stock units prone to high internal resistance or rapid insulation breakdown. The kit is built to match OE mounting and electrical fitment for a wide range of Nissan, Infiniti and Suzuki engines, letting you swap components without major modification.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engine sizes will this ignition coil and plug set fit?\u003c\/h3\u003e\n\u003cp\u003eThis kit covers many model years and engine sizes across Nissan, Infiniti and Suzuki lines. It’s targeted at 1.6L–2.5L petrol four-cylinders and some 5.0–5.6L Infiniti V8 applications where UF549-style coils are specified.
