The constant thermal stress from the engine bay causes micro-cracks in the OEM epoxy housing, allowing moisture intrusion and eventual cross-firing between terminal posts. Combined with natural electrode erosion on aging spark plugs, this degradation leads to high RPM misfires, sluggish throttle response, increased unburnt emissions, and noticeable drops in fuel economy. When resistance builds in the secondary ignition circuit, it places excessive load on the powertrain control module (PCM) coil drivers, risking wider, more expensive electrical system issues.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement ignition coil pack and Motorcraft spark plug kit tackles these thermal degradation issues directly at the source. The upgraded coil unit utilizes high-dielectric epoxy potting and pure copper wire windings to optimize energy transfer and fiercely resist heat soak under heavy load conditions. By delivering a stronger, more consistent spark duration, it effectively prevents spark blowout during high cylinder pressures. The included set of six genuine Motorcraft spark plugs features precisely engineered electrodes tailored specifically for the Cologne V6 combustion chamber, ensuring complete air-fuel atomization, restoring baseline torque output, and maximizing the overall lifespan of your truck's ignition circuit.\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;\"\u003e2005-2007 Mazda B4000\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;\"\u003e4.0L Cologne V6 (SOHC) \/ UN105 Platform\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;\"\u003e207 hp \/ 238 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;\"\u003e90TF12029A1A, E9DF12029AA, E9DZ12029A, F0TZ12029A, F1DZ12029A, F57U12029AA, F57Z12029A, F57Z12029B, F82U12029AA, FOTZ12029A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Mazda B4000 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2006 Mazda B4000 4.0L V6\u003c\/li\u003e\n  \u003cli\u003e2007 Mazda B4000 4.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to withstand the severe demands of payload hauling and off-road driving, restoring peak ignition performance guarantees your B4000 retains its legendary dependability and crucial low-end torque when towing heavy loads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50139869937912,"sku":"DS-EH9KE35ZC","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-mazda-b4000-2005-2007-4-0l-v6-1.jpg?v=1786462131","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-mazda-b4000-2005-2007-4-0l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
