Built with a 0.044-inch gap, a 5,000-ohm resistor, a 14.00 mm thread diameter and a 19.05 mm reach, they match fitments listed by part references such as BKR7EIX-11, XP3922, and XS3922. The center electrode uses iridium for precise spark delivery while the core is platinum for durability, making this pack suitable for drivers seeking consistent combustion and long service life.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these plugs affect starting reliability and throttle response?\u003c\/h3\u003e\n\u003cp\u003eThe fine-wire iridium tip produces a concentrated, consistent spark that helps engines ignite the air-fuel mixture more cleanly. That sharper spark can reduce misfires and improve throttle consistency under varied driving conditions. These plugs are particularly effective where precise ignition timing matters, such as higher-revving L4 sport engines.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIridium center tip for a focused spark and steady ignition\u003c\/li\u003e\n  \u003cli\u003e5000-ohm resistor reduces electrical interference\u003c\/li\u003e\n  \u003cli\u003eFactory-style 0.044\" gap preserves original ignition characteristics\u003c\/li\u003e\n  \u003cli\u003eDesigned reach (19.05 mm) ensures correct combustion chamber placement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these fit my Honda or Acura L4 engine?\u003c\/h3\u003e\n\u003cp\u003eCompatibility covers multiple L4 applications — check engine codes and gap specifications before purchase. Common compatible vehicles include Acura Integra (2001 B18C5), RSX (2002–2006 K20A series), CSX Type S (2007–2010 K20Z3), and a broad range of Honda Civic and S2000 years noted by the manufacturer.
