2016 Ford Escape Spark Plug Guide

Quick Reference: 2016 Ford Escape Spark Plug Specifications

Note: Always verify the part number and gap with your vehicle's owner's manual or the plug manufacturer before installation.

Why the Right Spark Plug Matters

Choosing the correct spark plug is critical for engine performance, fuel economy, and longevity. It's not just about finding a plug that threads in; it's about thermal performance and electrical efficiency.

• Heat Range: This is a plug's ability to dissipate heat. An engine that runs hot, like the turbocharged EcoBoost engines, requires a "colder" plug that transfers heat quickly to the cylinder head to prevent pre-ignition (knock). A naturally aspirated engine like the 2.5L uses a "hotter" plug that retains enough heat to burn off carbon deposits. Using the wrong heat range can lead to engine damage or poor performance.
• Electrode Material: The material of the center and ground electrodes determines the plug's lifespan and performance. The 2016 Escape engines use Iridium-tipped fine-wire plugs from the factory.
  • Iridium/Platinum: These precious metals have extremely high melting points and are very hard, allowing for a very fine-wire center electrode. This sharp point requires less voltage to create a spark, ensuring a consistent and powerful ignition event. They offer the longest service life, typically around 100,000 miles.
  • Copper: While once the standard, copper plugs have a much larger electrode and wear out significantly faster, often needing replacement every 30,000 miles. They are not recommended for the 2016 Escape, as the ignition system is designed for fine-wire plugs.

How to Gap a Spark Plug

Even pre-gapped plugs should be checked before installation. Shipping and handling can easily close the gap.

1. Use the Right Tool: Use a dedicated spark plug gap tool, either a feeler gauge style or a ramp-style gauge. Do not use a coin-style gapper, as they can damage the fragile fine-wire tip on iridium plugs.
2. Measure Carefully: Slide the appropriate wire or feeler gauge between the center electrode and the ground electrode. It should slide through with a slight drag. If it's too loose or too tight, the gap is incorrect.
3. Adjust Gently: To adjust, only bend the ground strap. Never pry against or put pressure on the center electrode. Use the adjustment slot on your gapping tool to gently bend the ground strap up or down until the correct measurement is achieved.

Replacement Procedure Tips for 2016 Ford Escape

The 2016 Escape uses a modern Coil-On-Plug (COP) ignition system. This means each spark plug has its own ignition coil sitting directly on top of it, eliminating the need for a distributor and spark plug wires.

1. Coil Removal: After removing the engine cover, you will see the tops of the ignition coils. Disconnect the electrical connector from the coil, then undo the single small bolt (typically 8mm) holding the coil in place. Gently twist and pull the coil straight up to remove it from the spark plug well.
2. The Anti-Seize Debate: Modern Motorcraft and NGK plugs have a special trivalent or nickel plating that acts as an anti-seize agent, preventing them from getting stuck in the aluminum cylinder head. For this reason, Ford and NGK officially recommend not using additional anti-seize compound on the plug threads. Applying it can lead to over-torquing, as the lubrication reduces friction, potentially stretching the plug threads or damaging the cylinder head.
3. Use Dielectric Grease: While you shouldn't put anti-seize on the threads, you should apply a small amount of dielectric grease to the inside of the ignition coil boot. This grease prevents the boot from sticking to the spark plug's porcelain, protects against moisture, and ensures a good electrical connection. Do not get any on the plug tip or electrodes.
4. Torque is Critical: Always use a torque wrench. Over-tightening can stretch the plug's metal shell and cause it to fail, while under-tightening can allow hot combustion gasses to leak past the threads.

Known Issues

Fortunately for 2016 Escape owners, these engines do not suffer from the infamous two-piece spark plug issue. That problem was primarily on Ford's 3-valve V8 engines (e.g., 5.4L Triton) from an earlier era. The plugs used in the 2016 Escape feature a robust, one-piece shell design that is not prone to breaking in the cylinder head during removal, provided standard removal procedures are followed on a cool engine.
