Over time, heat soak breaks down the internal epoxy insulation and primary\/secondary copper windings, causing dielectric breakdown, micro-arcing, and intermittent misfires under heavy load. Concurrently, standard OE spark plug ground electrodes erode from spark discharge and combustion heat, increasing the electrode gap. This widened gap demands higher firing voltage from an already thermally stressed coil, escalating electrical resistance, inducing hesitation, and triggering DTC misfire codes (P0300–P0304).\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete tune-up package provides four direct-fit pencil ignition coils engineered with high-dielectric epoxy potting, thermal-resistant silicone boots, and heat-stabilized magnetic steel cores to prevent voltage leakages under high underhood temperatures. Matched with four fine-wire iridium-tipped spark plugs, the kit ensures an ultra-low required firing voltage and superior resistance to spark erosion. The ultra-fine iridium center electrode concentrates electrical energy for immediate flame kernel propagation, ensuring complete fuel burn in high-pressure direct-injection combustion chambers without premature arc breakdown.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2023-2025 Mazda CX-50\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eSkyactiv-G 2.5L (PY-VPS) \/ VA Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e187 hp \/ 186 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003ePE2018100, UF656, PE2018100A, UF805, P51B18100, PE0118100, PE0118100A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2023 Mazda CX-50 2.5 S (Base, Select, Preferred, Preferred Plus, Premium, Premium Plus) 2.5L L4\u003c\/li\u003e\n  \u003cli\u003e2024 Mazda CX-50 2.5 S (Select, Preferred, Premium, Premium Plus) 2.5L L4\u003c\/li\u003e\n  \u003cli\u003e2025 Mazda CX-50 2.5 S (Select, Preferred, Premium, Premium Plus) 2.5L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the VA Chassis CX-50?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2023-2025 Mazda CX-50 equipped with the naturally aspirated \u003cstrong\u003eSkyactiv-G 2.5L\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for direct installation?\u003c\/strong\u003e\u003cbr\u003e Yes, the iridium spark plugs are factory pre-gapped to meet OEM Mazda high-compression ignition tolerances right out of the box.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Engineering Standard\u003c\/h3\u003e\n\u003cp\u003eModern Skyactiv engines require tight ignition tolerances to maximize dynamic compression and maintain precise flame propagation.
