A-Premium Iridium Platinum Spark Plugs for L4 Turbo 2.0/2.3L — Pack of 4, Fine-Wire, OEM Fit

A-Premium Iridium Platinum Spark Plugs (pack of 4) are fine-wire, dual-alloy spark plugs engineered for 4-cylinder turbocharged engines to deliver reliable ignition and long service intervals.

These spark plugs combine an iridium-tipped center electrode and a platinum core to balance durability with precise spark control for modern turbocharged 4-cylinder engines. Designed as direct-fit replacements for specific Ford and Lincoln applications, this 4-piece set matches OEM dimensions and electrical resistance so installation is straightforward and performance characteristics remain consistent with factory expectations.

Which vehicles and engines will these spark plugs fit?

These A-Premium plugs are intended for 4-cylinder, turbocharged Ford and Lincoln engines from the model years and variants listed by the manufacturer. They fit a range of Ford Escape, Edge, Explorer, Focus, Fusion, Taurus, Mustang models and several Lincoln MK series vehicles when equipped with the specified 2.0L or 2.3L turbocharged L4 engines.

• Compatible reference numbers include 96588, LTR6DI8, CB5E12405AA, CYFS12Y2.
• Fitment covers Escape, Edge, Explorer, Focus, Fusion (2013–2017), Taurus, Mustang (select years), Lincoln MKC/MKZ/MKT when 4-cylinder turbocharged.
• Designed for the 4-cylinder turbocharged engine variants only; verify engine code before purchase.

What are the key specifications and materials of these plugs?

The plugs use an iridium tip on the center electrode and a platinum core, combining hard-wearing contact metallurgy with a fine wire geometry for efficient spark delivery. They include an internal resistor to meet OEM electrical noise suppression standards and are sized to match factory threads and reach.

• Center electrode tip: iridium; center electrode core: platinum.
• Electrical resistance: 5000 ohms; gap range: 0.027"–0.031" (inches).
• Mechanical dimensions: 14.00 mm thread diameter, 25.00 mm reach, 53.00 mm insulator height, 5/8" hex.

How often should these iridium-platinum plugs be changed?

Iridium and platinum alloys are chosen for extended life compared with standard copper plugs, so replacement intervals are longer while maintaining stable ignition performance. Follow manufacturer guidance and monitoring for your vehicle, but a common service interval range for similar dual-alloy plugs is tens of thousands of miles.

• Recommended replacement interval: approximately 80,000–100,000 miles under typical operating conditions.
• Check spark plug condition during major tune-ups and if ignition-related symptoms arise.
• Always confirm intervals with the vehicle’s service manual and driving habits.

How do I confirm fit and install these plugs correctly?

Before purchasing, cross-check the listed reference numbers and engine configuration (4-cylinder turbocharged) against your vehicle’s OEM parts list. Installation requires standard spark plug socket tools and correct torque to protect the threads and ensure reliable sealing and heat transfer.

• Verify part references (96588, LTR6DI8, CB5E12405AA, CYFS12Y2) against OEM numbers.
• Use a 5/8" socket and torque to vehicle manufacturer specifications; do not overtighten.
• Set gap within 0.027"–0.031" if needed and replace in full sets of four for uniform performance.

Who is this for: These A-Premium Iridium Platinum spark plugs are aimed at owners and technicians working on late-model Ford and Lincoln vehicles with 4-cylinder turbocharged engines who want a long-life, direct-fit replacement that mirrors OEM dimensions and electrical properties. They suit drivers seeking durable ignition components with predictable maintenance intervals, garages performing scheduled tune-ups, and DIY mechanics who prefer premium dual-alloy plugs for turbocharged L4 applications.
