2025 Ford Escape — Spark Plug Type, Gap & Torque

Quick reference

Note: 2025 production part numbers can vary by calibration and market. Always confirm the exact Motorcraft and any cross-referenced NGK/Denso/ACDelco part number by VIN with Ford service information, the under-hood emissions label, or a reputable catalog. Do not substitute heat ranges.

Why the right plug matters

Choosing the correct plug is more than just thread size. Heat range determines how quickly the plug sheds combustion heat. Too hot and you risk pre-ignition; too cold and you’ll foul under light load—both can trigger misfires on EcoBoost engines. Electrode material matters, too:

• Iridium: The OE choice on modern Ford Escape engines. A very fine-wire center electrode delivers strong spark with low required voltage and excellent wear resistance—ideal for 100k-mile intervals.
• Platinum: Longer life than copper, but not as durable as iridium. Acceptable if specified, but most 2025 Escape engines are iridium from the factory.
• Copper (nickel): Great conductivity but short life. Use mainly for diagnostics or performance tuning where short intervals are acceptable.

Turbocharged EcoBoost engines (1.5L and 2.0L) are especially sensitive to correct heat range and gap because cylinder pressures rise quickly under boost. Using the right iridium plug, at the right gap, helps prevent high-load misfires and protects ignition coils.

How to gap a spark plug

Most iridium plugs arrive pre-gapped to a spec close to the label on your Escape’s core support/emissions decal. Still, always measure:

1. Use a wire-style gap gauge (not a coin wedge) sized in thousandths of an inch and millimeters.
2. Slide the correct wire through the gap—there should be a slight drag.
3. If adjustment is needed, bend only the ground strap with a dedicated gapping tool. Do not pry on the iridium center electrode—it can crack.
4. For turbo EcoBoost engines, stay at the tight end of spec (about 0.028–0.031 in / 0.70–0.80 mm). The hybrid’s naturally aspirated 2.5L typically runs a wider gap (~0.044 in / 1.10 mm).
5. Re-check after any adjustment.

Replacement procedure tips (2025 Escape engines)

All 2025 Escape engines use coil-on-plug (COP) ignition—no distributor. The basic steps are similar across the 1.5L, 2.0L, and 2.5L:

• Battery and access: Key off. On some trims, remove the engine cover for access. Hybrid/PHEV models may have additional covers—follow proper shutdown procedures.
• Coil removal: Unplug the COP electrical connector, remove the retaining bolt, and twist the coil boot gently to break any seal before pulling upward. Label coils if needed.
• Cleanliness: Blow out plug wells with compressed air before removing plugs to avoid dropping debris into cylinders.
• Removal: Use a spark plug socket with extension. Break loose smoothly. If a plug feels stuck, work it out in small increments; do not force it hot.
• Anti-seize: Motorcraft and most premium iridium plugs are nickel-plated. Ford does not recommend anti-seize. If you choose to apply it, reduce torque by ~20–30%—but the safer move is to install dry, clean threads.
• Torque: Thread in by hand first to avoid cross-threading. Use a torque wrench to the spec appropriate to your thread size (see table). Aluminum heads demand accurate torque.
• Dielectric grease: A small smear inside the coil boot helps seal out moisture and eases future removal. Do not flood the spring contact point.
• Final check: Reconnect coils, clear any debris, and road test for smooth acceleration under load.

Known issues

• Not applicable: The infamous Ford 3-valve V8 “two-piece” spark plug breakage (cracked porcelain and stuck shells) does not apply to the 2025 Escape—those were older 4.6/5.4/6.8L engines.
• EcoBoost misfire under boost: As gaps grow with age past ~0.035 in, some EcoBoost engines may stumble on hard acceleration. Fresh iridium plugs gapped to the tight end of spec usually resolve this.
• Oil in plug wells: Valve cover tube seals can seep over time, softening coil boots and causing intermittent misfire. Inspect boots and replace as needed.
• Cross-threading/aluminum heads: Beginning the plug by hand is critical. A thread chaser can help if you feel resistance early on.
