autoexact Ignition Coil and Iridium Spark Plug Kit for Ford/Mazda 2.0L–2.3L — 4-Pack Coils & Pre-Gapped Plugs

If your vehicle fits the listed model years and engines, this combined coil-and-plug set replaces worn ignition components in one service interval, reducing repetitive repairs and simplifying installation. The package is designed to match original equipment fitment for many Focus, Transit Connect, Escape, Mazda 3/6, Tribute, Mariner and related models, and it ships with pre-applied dielectric grease and pre-gapped fine-wire iridium plugs to speed a DIY swap.

Which vehicles and engines does this set fit?

This kit is intended for selected Ford, Mazda and Mercury cars and crossovers equipped with 2.0L or 2.3L inline-4 engines across the mid-2000s to early-2010s. Always confirm year, make, model and engine before ordering to avoid misfits.

• Common fits include 2005–2011 Focus 2.0L, 2010–2013 Transit Connect 2.0L
• Also compatible with 2005–2008 Escape 2.3L, 2003–2007 Focus 2.3L, 2004–2005 Mazda 3 2.3L
• Coverage extends to 2005–2006 & 2008 Tribute 2.3L and 2005–2008 Mercury Mariner 2.3L
• If unsure, provide your VIN to confirm fitment with seller support

How will installing this kit affect engine performance?

Replacing old coils and worn spark plugs can restore consistent ignition events when misfires or rough running are caused by degraded ignition parts. The iridium plugs and full-wind coils are built for stable spark delivery under typical driving conditions.

• Fine-wire iridium tips for durable, consistent sparks and efficient combustion
• Fully wound primary/secondary copper windings for steady output
• Epoxy potting and heat-resistant housing to resist moisture and vibration
• Supports diagnosis codes commonly tied to ignition faults (e.g., P0300–P0308)

What comes in the box and what tools or specs are needed?

The kit includes four ignition coils and four pre-gapped iridium spark plugs—everything required to refresh one bank or all cylinders depending on your engine layout. The parts are factory assembled to facilitate a direct swap using basic hand tools.

• Contents: 4 ignition coils, 4 pre-gapped iridium plugs, factory-applied green dielectric grease
• Recommended spark plug torque: approximately 11.06 ft·lb (15 N·m)
• Designed for plug thread 14 mm with tapered seat and 0.052 in preset gap
• Installation typically requires basic hand tools and a torque wrench for plugs

What quality checks and support are included?

Each coil is high-voltage tested for secondary output and checked for fit and function before shipping. The manufacturer backs the kit with a two-year warranty plus lifetime technical help for compatibility or installation questions.

• High-voltage test: approximately 35±2 kV secondary output verification
• Sealed housings and PCB-aligned ignition modules for reliable operation
• OE-equivalent references covered (e.g., FD505 and several common part numbers)
• Seller support accepts VIN or vehicle details to confirm correct application

Who is this for: This kit is aimed at owners and independent mechanics working on mid-2000s to early-2010s Ford, Mazda and Mercury 2.0L/2.3L engines who want a full ignition refresh in a single purchase. It's appropriate for drivers experiencing ignition-related symptoms, DIYers seeking a guided tune-up with pre-gapped plugs, and shops that prefer stocking a complete coil-plus-plug replacement set to speed service turnaround. Remember to verify fitment for your exact vehicle and engine before ordering.
