<h2>Direct-Fit Ignition Tune-Up Kit for 2005-2008 Ford Escape</h2> <p><strong>Primary Function:</strong> Restores factory secondary ignition output and cylinder combustion efficiency by replacing degraded coil-on-plug assemblies and eroded spark plugs.</p> <h3>The Stock Escape Secondary Ignition Breakdown</h3> <p>Under-hood thermal cycling on the CD2 platform causes the factory coil casing epoxy and internal winding insulation to deteriorate over time. This thermal fatigue triggers dielectric breakdown, internal arcing, and intermittent misfires under load. Simultaneously, enlarged gaps on worn factory spark plugs place excessive electrical strain on the ignition drivers, yielding unburnt fuel carryover, reduced fuel economy, and erratic idle quality.</p> <h3>The Engineering Solution</h3> <p>This service kit provides four direct-fit coil-on-plug units wound with high-conductivity internal copper wiring and moisture-sealed blade terminals to prevent high-voltage leakage. Paired with fine-wire iridium spark plugs that resist electrode erosion and minimize flame kernel quenching, this kit ensures crisp flame propagation, dependable cold starts, and consistent high-RPM spark delivery.</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;">2005-2008 Ford Escape</td> </tr> <tr> <td style="padding:8px;"><strong>Engine / Chassis</strong></td> <td style="padding:8px;">Duratec 23 (2.3L DOHC) / CD2</td> </tr> <tr style="background-color: #f9f9f9;"> <td style="padding:8px;"><strong>Stock Output</strong></td> <td style="padding:8px;">153 hp / 152 lb-ft (Approx)</td> </tr> <tr> <td style="padding:8px;"><strong>Part Number</strong></td> <td style="padding:8px;">FD505, FD-505, UF621, UF-621</td> </tr> </table> <h3>Compatibility</h3> <ul> <li>2005 Ford Escape 2.3L L4 (XLS, XLT)</li> <li>2006 Ford Escape 2.3L L4 (XLS, XLT)</li> <li>2007 Ford Escape 2.3L L4 (XLS, XLT)</li> <li>2008 Ford Escape 2.3L L4 (XLS, XLT)</li> </ul> <h3>The Ford Escape Utility Standard</h3> <p>Engineered to handle severe daily commuting and light-utility hauling demands, this direct-replacement ignition package provides the rugged electrical integrity required to pull loads cleanly without check-engine lights or power drop-off.</p>
