<h2>Direct Replacement Ignition Service Kit for 2014-2020 Mazda 3</h2> <p><strong>What it Does:</strong> Complete four-cylinder ignition service kit designed to restore primary and secondary ignition voltage, eliminate misfires, and maintain combustion stability across the RPM band.</p> <h3>The Stock Skyactiv Ignition Breakdown</h3> <p>Mazda Skyactiv-G engines operate at elevated cylinder pressures with compression ratios reaching up to 14.0:1. This demanding combustion environment accelerates dielectric degradation in factory pencil coils. Over extended heat cycles, OEM epoxy insulation breaks down, leading to internal shorting, weak spark propagation, and unburned fuel entering the exhaust. Worn electrode gaps further increase secondary voltage demand, resulting in hesitations, rough idle, and P030X misfire fault codes.</p> <h3>The Engineering Solution</h3> <p>This refresh package pairs high-output direct-fit pencil coils with fine-wire DILKAR7G11GS iridium spark plugs. Each coil utilizes reinforced thermoplastic housings, high-purity copper windings, and high-dielectric silicone boots to prevent spark flashover and thermal breakdown. The laser-welded iridium spark plugs offer superior thermal dissipation and ultra-focused spark kernel development, ensuring complete flame-front propagation under high load.</p> <h3>Technical Specifications</h3> <table width="100%" style="border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;"> <tr style="background-color: #f9f9f9;"> <td style="padding:8px;"><strong>Fitment</strong></td> <td style="padding:8px;">2014-2020 Mazda 3</td> </tr> <tr> <td style="padding:8px;"><strong>Engine / Chassis</strong></td> <td style="padding:8px;">2.0L (PE-VPS), 2.5L (PY-VPS) Skyactiv-G / BM, BN, BP</td> </tr> <tr style="background-color: #f9f9f9;"> <td style="padding:8px;"><strong>Stock Output</strong></td> <td style="padding:8px;">155-186 hp / 150-186 lb-ft (Approx)</td> </tr> <tr> <td style="padding:8px;"><strong>Part Number</strong></td> <td style="padding:8px;">UF656, UF-656, PE2018100A, P51B18100, H6T61272, DILKAR7G11GS</td> </tr> </table> <h3>Compatibility</h3> <ul> <li>2014-2018 Mazda 3 (BM / BN Chassis) 2.0L 4-Cylinder Skyactiv-G</li> <li>2014-2018 Mazda 3 (BM / BN Chassis) 2.5L 4-Cylinder Skyactiv-G</li> <li>2019-2020 Mazda 3 (BP Chassis) 2.0L 4-Cylinder Skyactiv-G</li> <li>2019-2020 Mazda 3 (BP Chassis) 2.5L 4-Cylinder Skyactiv-G</li> </ul> <h3>The Mazda Performance Caliber</h3> <p>Engineered for high-efficiency direct-injected powertrains, this kit restores crisp throttle response, stabilizes idle quality, and preserves the linear power delivery expected from your Skyactiv engine.</p>
