Over heat cycles, the factory coil-on-plug boots and epoxy potting harden, causing micro-fractures in the internal insulation. This breakdown leads to internal dielectric leakage, intermittent spark dropouts under wide-open throttle, and erratic readings across the ionic current knock detection circuit. Concurrently, factory plugs suffer electrode erosion, widening gaps and increasing secondary voltage demands beyond what degraded coils can sustain.</p> <h3>The Engineering Solution</h3> <p>This kit supplies 10 precision-wound ignition coils engineered with high-dielectric epoxy resin to prevent high-voltage arcing under sustained load. Matched with 10 fine-wire iridium spark plugs, the assembly lowers ionization voltage requirements and delivers rapid spark discharge. Fine-wire iridium ground and center electrode geometry resists thermal ablation and maintains gap stability under peak cylinder pressure, ensuring complete combustion across all ten combustion chambers without throwing DME misfire codes.</p> <h3>What's Included</h3> <ul> <li>10 Ignition Coils</li> <li>10 Iridium Spark Plugs</li> </ul> <h3>Technical Specifications</h3> <div style="overflow-x: auto; margin-bottom: 20px;"> <table width="100%" style="border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;"> <tr style="background-color: #f9f9f9;"> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Fitment</th> <td style="padding:10px; border: 1px solid #e0e0e0;">2006-2010 BMW M6</td> </tr> <tr> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Engine / Chassis</th> <td style="padding:10px; border: 1px solid #e0e0e0;">S85B50 / E63, E64</td> </tr> <tr style="background-color: #f9f9f9;"> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Stock Output</th> <td style="padding:10px; border: 1px solid #e0e0e0;">500 hp / 383 lb-ft</td> </tr> <tr> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Replaces OEM Part #</th> <td style="padding:10px; border: 1px solid #e0e0e0;">UF572, 9409, 178-8457, GN10563, IC652, 48730, U5211, C-994, C1643, 5C1700, 23-0155, 52-2055, 2IGC0362, EBC1083, 921-2254, 3IC346, 36-8271, 2505-300780, E1072, 12137835108, 12137841556</td> </tr> </table> </div> <h3>Compatibility</h3> <ul> <li>2006 BMW M6 Base 5.0L V10</li> <li>2007 BMW M6 Base 5.0L V10</li> <li>2008 BMW M6 Base 5.0L V10</li> <li>2009 BMW M6 Base 5.0L V10</li> <li>2010 BMW M6 Base 5.0L V10</li> </ul> <h3>Frequently Asked Questions &amp; Fitment Warnings</h3> <h4>Does this fit the E63/E64 M6?</h4> <p>Yes, this is a direct fit for the 2006-2010 BMW M6 equipped with the <strong>S85B50</strong> 5.0L V10 engine. <strong>This kit is not compatible with standard 6-Series inline-6 or V8 models (N52, N62), nor is it a universal ignition package.</strong></p> <h4>Are spark plug wires included or required with this kit?</h4> <p>No, the S85 engine utilizes a direct coil-on-plug configuration, meaning plug wires are neither included nor required.</p> <h3>The BMW Precision Standard</h3> <p>High-revving European performance powerplants demand precise secondary spark timing and matched impedance to operate without check engine lights or ionic sensor fault codes.</p>
