Over time, the internal primary and secondary copper windings delaminate, producing weak spark output, intermittent hesitation under boost, rough idle, and typical P0300-P0304 cylinder misfire fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete 4-cylinder ignition service kit upgrades the ignition circuit using heavy-duty coil-on-plug assemblies engineered with high-grade internal copper windings and reinforced thermal insulation. Coupled with fine-wire iridium-tipped spark plugs that require lower ionization voltage, this combination ensures stable arc propagation, consistent ignition timing under load, and extended service life without thermal degradation.\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;\"\u003e2001-2006 Volkswagen Golf\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;\"\u003e1.8L Turbo 20V (EA113) \/ Mk4 (Typ 1J)\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;\"\u003e180 hp \/ 174 lb-ft (Approx)\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;\"\u003eUF411, 06A905115\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Volkswagen Golf 1.8L L4 Turbo (GTI \/ GLS)\u003c\/li\u003e\n  \u003cli\u003e2002 Volkswagen Golf 1.8L L4 Turbo (GTI \/ 337 Edition)\u003c\/li\u003e\n  \u003cli\u003e2003 Volkswagen Golf 1.8L L4 Turbo (GTI \/ 20th Anniversary Edition)\u003c\/li\u003e\n  \u003cli\u003e2004 Volkswagen Golf 1.8L L4 Turbo (GTI)\u003c\/li\u003e\n  \u003cli\u003e2005 Volkswagen Golf 1.8L L4 Turbo (GTI)\u003c\/li\u003e\n  \u003cli\u003e2006 Volkswagen Golf 1.8L L4 Turbo (GTI)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Volkswagen Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered strictly to European diagnostic and factory resistance tolerances, this direct-fit ignition kit ensures precise signal feedback to the Motronic ECU, eliminating check engine lights and preserving smooth power delivery throughout the entire rev range.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452879212792,"sku":"DS-ELDVNO2Z6","price":100.95,"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-volkswagen-golf-2001-2006-1-8l-1.jpg?v=1788724196","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-volkswagen-golf-2001-2006-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
