Direct OE replacement for OEM numbers DG521, FD509, SP509, and IC697. Each component is precision-engineered to match factory specifications, ensuring seamless integration without modifications. Always verify your original coil boot color (e.g., brown boots for 2008 models) and use Amazon's fitment tool for confirmation to avoid installation issues and ensure optimal performance.
Enhanced Ignition Performance - Experience high performance with these ignition coils that deliver up to 20% stronger spark energy than standard OEM units. The advanced design features highly conductive copper windings and high-dielectric epoxy encapsulation, ensuring stable spark delivery across all RPM ranges. This eliminates common issues like misfires, rough idling, and power loss while significantly improving throttle response, acceleration, and overall engine efficiency in your Ford or Lincoln V8/V10 engine, providing a smoother and more reliable driving experience.
Premium Iridium Spark Plugs - Included iridium spark plugs feature double iridium electrodes and advanced ceramic insulation for superior spark concentration, faster ignition, and extended service life. The corrosion-resistant design minimizes spark gap growth, ensuring consistent combustion and optimal fuel efficiency. Combined with our high-performance ignition coils, this setup restores engine power, reduces emissions, and enhances overall performance, making your vehicle run like new even under demanding conditions.
Complete Kit & Professional Installation - Get everything needed for a professional upgrade: 8 DG521 ignition coils and 8 premium iridium spark plugs.
