<h2>Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2014-2016 BMW 2 Series</h2> <p><strong>Primary Function:</strong> Restores factory ignition energy and precise combustion timing to eliminate misfires, rough idle, and unburned fuel under turbocharged boost loads.</p> <h3>The Stock 2 Series Ignition Breakdown</h3> <p>Factory ignition coils on the turbocharged N55 straight-six operate in a tightly enclosed, high-heat cylinder head environment. Over heat cycles, thermal fatigue degrades the internal dielectric resin and epoxy potting, causing micro-arcing, secondary resistance drift, and premature coil breakdown. Combined with standard electrode erosion on aging spark plugs, cylinder pressures under boost routinely blow out weak sparks, leading to hesitation, hesitation under load, and check engine lights (CEL) with misfire codes.</p> <h3>The Engineering Solution</h3> <p>This direct-replacement kit pairs six reinforced coil-on-plug assemblies with six laser-welded iridium spark plugs. The coils feature high-conductivity internal copper windings and thermal-resistant thermoplastic housings designed to withstand elevated underhood operating temperatures. The iridium spark plugs utilize fine-wire center electrodes that reduce the required firing voltage, providing consistent spark propagation, stable flame kernels, and total resistance to fouling under sustained acceleration.</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;">2014-2016 BMW 2 Series (3.0L L6)</td> </tr> <tr> <td style="padding:8px;"><strong>Engine / Chassis</strong></td> <td style="padding:8px;">N55B30O0 / F22, F23</td> </tr> <tr style="background-color: #f9f9f9;"> <td style="padding:8px;"><strong>Stock Output</strong></td> <td style="padding:8px;">320 hp / 330 lb-ft (Approx)</td> </tr> <tr> <td style="padding:8px;"><strong>Part Number</strong></td> <td style="padding:8px;">UF515, UF-515, UF522, UF-522</td> </tr> </table> <h3>Compatibility</h3> <ul> <li>2014 BMW M235i (3.0L L6 Turbo - F22)</li> <li>2015 BMW M235i / M235i xDrive (3.0L L6 Turbo - F22, F23)</li> <li>2016 BMW M235i / M235i xDrive (3.0L L6 Turbo - F22, F23)</li> </ul> <h3>The BMW Precision Standard</h3> <p>Engineered to meet tight European tolerances, this ignition service package ensures zero-fault DME communication, clean combustion cycles, and factory idle stability without triggering misfire-related trouble codes.</p>
