<h2>High-Output Ignition Coils &amp; Iridium Spark Plugs for 2012-2016 BMW 3 Series (N20/F30)</h2> <p><strong>Engineered to restore proper ignition timing and eliminate misfires, this direct-replacement kit ensures optimal fuel burn for the N20 powerplant.</strong></p> <h3>The Stock 3 Series Ignition Weakness</h3> <p>The BMW N20 2.0L turbocharged engine is known for accelerating ignition component wear under high combustion pressures. Factory ignition coils degrade from continuous thermal cycling and under-hood heat soak, causing micro-cracks in the epoxy housing and subsequent voltage leaks. When the internal windings break down, the coil cannot deliver the required kilovolts. Concurrently, standard spark plugs suffer electrode erosion, widening the gap and increasing resistance. This manifests as rough idling, delayed throttle response, and cylinder misfires under heavy load, frequently triggering Drivetrain Malfunction warnings.</p> <h3>The Engineering Solution</h3> <p>This comprehensive ignition package resolves N20 spark degradation by upgrading spark delivery and execution. The ignition coils feature high-temp dielectric epoxy and advanced copper windings, ensuring a stable, high-energy voltage output even during peak boost. The accompanying laser-welded iridium spark plugs provide superior conductivity and a highly concentrated spark. Iridium's extreme hardness prevents rapid electrode wear, maintaining strict gap tolerances over thousands of miles. Upgrading to this system eliminates voltage drop-offs, yielding a complete combustion cycle. This translates directly to restored factory horsepower and a stabilized idle, and maximum fuel economy.</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;">2012-2016 BMW 328i 2.0L</td> </tr> <tr> <td style="padding:8px;"><strong>Engine / Chassis</strong></td> <td style="padding:8px;">N20B20 / F30</td> </tr> <tr style="background-color: #f9f9f9;"> <td style="padding:8px;"><strong>Stock Output</strong></td> <td style="padding:8px;">240 hp / 255 lb-ft (Approx)</td> </tr> <tr> <td style="padding:8px;"><strong>Part Number</strong></td> <td style="padding:8px;">UF592, 97506, GN10328, 12137594937</td> </tr> </table> <h3>Compatibility</h3> <ul> <li>2012 BMW 328i 2.0L</li> <li>2013 BMW 328i 2.0L</li> <li>2014 BMW 328i 2.0L</li> <li>2015 BMW 328i 2.0L</li> <li>2016 BMW 328i 2.0L</li> </ul> <h3>The BMW Precision Standard</h3> <p>Maintaining the engineering of a European chassis requires components meeting strict ECU parameters.
