LCWRGS Ignition Coil Pack Set for Ford 6.2L V8 — 8-Pack UF639 Direct-Fit, High-Energy Copper Windings

These LCWRGS ignition coils are a full set of eight direct-fit coil packs engineered to restore strong spark and reliable combustion in 6.2L V8 Ford trucks and vans.

This set replaces worn or failing ignition coils on Ford 6.2L engines, fit for many F150, F250, F350 Super Duty and E350 Super Duty model years. Designed to meet or exceed original equipment specifications, the coils use high-conductivity copper windings and durable epoxy insulation to deliver consistent performance and longer service life. The pack includes four coils for each bank (driver and passenger) so you can renew the entire ignition system at once and avoid intermittent misfires caused by marginal coils.

Which vehicles and part numbers are these coils compatible with?

These coils are made as direct-fit replacements for a defined range of Ford 6.2L V8 models and match common OEM reference numbers for easy ordering.

• Compatible with 2010–2014 Ford F150 6.2L V8 and 2011–2017 Ford F250/F350 6.2L V8.
• Also fits 2017 Ford E350 Super Duty 6.2L V8.
• Replaces OEM numbers UF631, UF639, C1800, C1801, 5C1857, 5C1858, DG525.

How do these coils affect engine performance and reliability?

Upgrading worn coils restores proper spark energy to each cylinder, which helps reduce misfires and rough idle without engine modifications. LCWRGS coils are specified to deliver approximately 15% more energy than many original coils, improving combustion consistency under load.

• Higher energy output for stronger, more consistent spark delivery.
• Improved conductor and epoxy for durability and heat resistance.
• Reduces symptoms like hesitation, rough idle, and poor fuel economy caused by failing coils.

Are these coils easy to install and what does the package include?

Yes — the coils follow OEM form and fit, so installation is straightforward with basic hand tools and common mechanical experience. The set covers both cylinder banks so you avoid mixing old and new coils, which can hide intermittent problems.

• Package contains 8 ignition coil packs: 4 driver-side and 4 passenger-side coils.
• Direct OEM-style connectors and mounting locations for bolt-on replacement.
• Includes a 24-month warranty and customer support from LCWRGS.

What maintenance signs indicate coil replacement is needed?

Common indicators include a persistent or intermittent check engine light, a noticeable drop in fuel economy, poor idle, or engine hesitation under acceleration. If diagnostics show cylinder misfire codes (P0300–P0308 range), replacing coils is a recommended next step when spark faults are suspected.

• Check engine light with misfire trouble codes is a key sign.
• Rough idle, stalling, or poor acceleration under load.
• Visible wear, cracked boots, or corrosion at coil connectors.

Who is this for: This complete set is aimed at Ford owners, fleet managers, and mechanics who want a reliable, full-bank replacement for 6.2L V8 ignition systems. It’s especially useful when one or more coils have failed or when preventive maintenance is desired to restore engine smoothness and prevent future misfires. If you own a compatible F150, F250, F350, or E350 with the 6.2L V8 and want a straightforward, OEM-form replacement with an extended warranty, this LCWRGS set is built for that purpose.
