Built with a laser-welded iridium center electrode and a durable ground electrode, they prioritize efficient spark formation, stable idle and consistent throttle response. The plugs are compatible with numerous part numbers (including BKR5EIX-11, BKR5EGP, IFR5E11 and others) to simplify cross-referencing when you’re choosing replacements for older or high-mileage vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles will these iridium plugs fit?\u003c\/h3\u003e\n\u003cp\u003eThese plugs match many compact and midsize models with 1.5–2.4L inline-four engines. Fitment covers several years for Toyota Corolla, Yaris, Matrix, Prius, Tacoma and Celica, plus Nissan Altima, Frontier, Sentra, Xterra and numerous Mitsubishi models like Lancer, Outlander and Eclipse.

That improved ignition can reduce misfires and support smoother throttle transitions, potentially aiding fuel economy under normal driving conditions.

Use a torque wrench and the vehicle manufacturer’s torque spec, and inspect ignition coils and wires while replacing plugs. If you’re uncertain, have a qualified technician fit them to ensure correct sealing and gap integrity.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCheck and use the vehicle OEM torque specification\u003c\/li\u003e\n  \u003cli\u003eInspect ignition coils, boots and wires at the same time\u003c\/li\u003e\n  \u003cli\u003eUse anti-seize on threads only if recommended by the vehicle manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does A-NAFTULY support this product after purchase?\u003c\/h3\u003e\n\u003cp\u003eA-NAFTULY includes customer support for fitment questions and offers a limited warranty period for manufacturer defects.
