Over time, thermal cycling degrades the factory coil epoxy insulation, resulting in internal secondary winding resistance drift and high-voltage dielectric breakdown. When paired with standard electrode gap erosion on aged plugs, the ignition system struggles to jump the gap under load. This leads to P0300–P0304 misfire codes, rough engine engagement during hybrid start-stop transitions, unburnt hydrocarbon build-up, and reduced fuel mileage.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service kit provides a matched overhaul for all four cylinders. Each coil-on-plug unit is engineered with high-purity oxygen-free copper windings and heat-resistant silicone boots to insulate against thermal breakdown and electrical arcing. The accompanying fine-wire iridium spark plugs lower the required breakdown voltage while providing a concentrated, stable spark kernel. This setup ensures rapid flame front propagation, clean combustion, and smooth internal combustion engine engagement.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2001-2009 Toyota Prius\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.5L 1NZ-FXE I4 \/ NHW11, NHW20\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e76 hp \/ 82 lb-ft (Gas Engine ICE)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF316, 90919-02240, 90919-02265, C1304, 5C1293, 6731306, 1788304\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001-2003 Toyota Prius Base (1.5L L4 1NZ-FXE, NHW11 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2004-2009 Toyota Prius Base (1.5L L4 1NZ-FXE, NHW20 Chassis)\u003c\/li\u003e\n  \u003cli\u003e2007-2009 Toyota Prius Touring (1.5L L4 1NZ-FXE, NHW20 Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Hybrid Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet exact OEM mechanical tolerances, this ignition overhaul ensures proper catalytic converter protection, zero check-engine lights, and factory-level thermal efficiency across long-distance commuter duty cycles.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448859529464,"sku":"DS-EOON4S7TB","price":84.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-toyota-prius-2001-2009-1-5l-1.jpg?v=1788662122","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-toyota-prius-2001-2009-1-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
