Optimized for Toyota engines, the BKR6E-11 spark plug delivers precise ignition with a copper-core electrode and triple-ground design for consistent combustion. Nickel-alloy shell resists corrosion while the tapered cut ground electrode reduces quenching for improved fuel efficiency. Direct-fit replacement ensures OEM-level performance in Camry, Corolla, and RAV4 models. Laser-welded iridium tip guarantees 60,000-mile durability with anti-fouling ceramic insulator. Cold-forged steel body withstands extreme cylinder pressures up to 1,200°F. Includes factory-pre-gapped 1.1mm setting for plug-and-play installation. Ideal for urban commuting, towing, and high-RPM driving conditions. Batch-tested for voltage consistency within ±5% tolerance. Ships in moisture-proof packaging with ISO9001-certified manufacturing.
