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

A-Premium Iridium Platinum Spark Plugs (pack of 4) are high-performance fine-wire ignition components designed to deliver reliable spark, long service life, and OEM-compatible fitment for 2.0L L4 Ford engines.

These spark plugs pair an iridium-tipped center electrode with a platinum core to provide consistent ignitability and extended wear resistance. Engineered to match original equipment dimensions and electrical resistance, they suit several Ford models equipped with 2.0L inline-4 engines. The set includes four plugs with a 0.036" gap, 14 mm thread diameter, and a 5/8" hex for straightforward installation using standard tools.

Will these plugs fit my vehicle?

They are made to fit vehicles that require reference numbers 90483 or LTR6EI9 and are compatible with multiple Ford applications using a 2.0L L4 engine. Always verify with your vehicle’s service manual or parts lookup to confirm compatibility before purchasing.

• Compatible models: Ford EcoSport (2018–2020), Focus (2012–2018), Transit Connect (2019–2021)
• Reference numbers supported: 90483, LTR6EI9
• Thread diameter: 14.00 mm; reach: 25.00 mm

How do these spark plugs improve ignition and performance?

The combination of an iridium tip and a platinum core reduces electrode erosion and maintains a sharp spark gap, which helps support reliable combustion. While not a power-adding upgrade by itself, improved ignitability contributes to steadier idle, smoother throttle response, and consistent starts compared with worn plugs.

• Center electrode tip: iridium for precise spark delivery
• Core material: platinum for enhanced durability
• Resistance: 5000 ohms to match modern ignition systems

What are the key specifications I should know before buying?

These plugs follow common OEM dimensions and electrical characteristics so they install and operate like factory parts. Knowing the physical and electrical specs helps confirm fitment and ensures compatibility with your ignition coil and boot design.

• Gap size: 0.036 inches; pre-gapped for typical 2.0L L4 setups
• Hex size: 5/8 inch for standard socket tools
• Insulator height: 52.50 mm; reach: 25.00 mm

How long will these spark plugs last and when should they be replaced?

Iridium-platinum spark plugs are built for extended service life compared to conventional copper plugs. The suggested replacement interval for best performance is generally between 80,000 and 100,000 miles, depending on driving habits and vehicle conditions.

• Recommended replacement: every 80,000–100,000 miles under normal driving
• Monitor for misfires, poor start, or rough idle as replacement indicators
• Use torque specs from your vehicle manual when installing

Who is this for: A-Premium Iridium Platinum Spark Plugs are aimed at owners and technicians seeking OEM-compatible replacement plugs for Ford 2.0L L4 engines who want a balance of long service life and dependable ignition. They suit daily drivers, fleet vehicles, and anyone performing a scheduled tune-up who prefers fine-wire, long-life plug technology over short-life copper options. Before installation, confirm part cross-reference and follow manufacturer torque and gap specifications to ensure safe, reliable operation.
