Bosch Ignition Coil replacement for Ford V8s 0221504704 — direct-fit, long-life coil

Bosch Ignition Coil 0221504704 is a direct-fit replacement coil engineered to meet or exceed OE performance for select Ford, Lincoln, and Mercury V8 engines.

If your V8 vehicle is showing signs of misfires, rough idle, or decreased fuel economy, replacing worn coils with a quality unit like Bosch 0221504704 restores reliable spark delivery and engine smoothness. Bosch designs each coil from durable materials to withstand heat, vibration, and corrosion, delivering consistent ignition voltage and long service life. This coil is sold individually and matches the original equipment’s fit and electrical properties for a straightforward swap.

Which vehicles and engines is this coil compatible with?

This Bosch coil fits a range of V8-equipped Ford, Lincoln, and Mercury models produced between the late 1990s and mid 2010s. Compatibility targets factory V8 ignition systems that require the same electrical connector and mounting style as the OE coil.

• Designed for select 1997–2016 Ford vehicles with V8 engines
• Compatible with many 2004–2011 Lincoln models using the same coil style
• Fits various 1998–2011 Mercury vehicles equipped with applicable V8s
• Sold individually—replace all eight coils per engine for full renewal

How does this coil improve engine performance and efficiency?

By delivering the correct ignition voltage and a long-lasting spark, the Bosch coil helps reduce misfires, improve combustion consistency, and stabilize idle. Better ignition timing and stronger sparks contribute to more complete fuel burn, which can reduce fuel usage and lower exhaust emissions when the rest of the ignition system is in good condition.

• Provides consistent high-voltage output for reliable combustion
• Minimizes misfires that lead to rough running and reduced MPG
• Maintains spark quality across thermal and mechanical stresses
• Helps lower unburned fuel in exhaust when paired with good plugs and wiring

What should I expect during installation and maintenance?

The 0221504704 is a direct-fit replacement designed to use the original mounting points and electrical connector, which simplifies swaps for DIYers and technicians. Basic precautions—disconnecting the battery and working on a cool engine—are recommended; no special programming is required for a like-for-like coil replacement.

• Direct-fit design uses the same bolt locations and plug connector as OE
• No additional module programming needed for like-for-like swaps
• Install time is typically short; follow vehicle torque specs for fasteners
• Recommend replacing spark plugs and inspecting wiring with coils for best results

What materials and construction features support long-term reliability?

Bosch builds these coils with premium materials chosen for thermal stability and corrosion resistance so they withstand engine bay conditions over time. The internal windings and insulation are engineered to retain performance under repeated heating cycles and vibration.

• High-grade insulation and winding materials resist breakdown under heat
• Robust housing protects internal components from moisture and road debris
• Corrosion-resistant terminals maintain strong electrical contact
• Engineered to meet or exceed original equipment durability standards

Who is this for: This Bosch 0221504704 ignition coil is for vehicle owners and mechanics who need a reliable, OEM-like replacement for a V8 ignition system. It suits DIY enthusiasts performing single-coil swaps, professional shops completing diagnostic repairs, and fleet operators replacing coils during scheduled maintenance. Remember: these coils are sold individually, and a full V8 engine typically requires eight coils for complete replacement.
