What spark plugs are best for 1.0 EcoBoost?
For the Ford 1.0 EcoBoost, the best spark plugs are the OEM iridium long-life plugs from Motorcraft, or equivalent iridium plugs from NGK or Denso that match Ford’s heat range and pre-gap. In practice, using Ford’s recommended plug is the safest choice.
The 1.0 EcoBoost is a turbocharged three-cylinder engine used in several Ford models. It relies on precise ignition timing and heat management to deliver efficiency and torque. Choosing the right spark plug matters for cold starts, misfire resistance, and fuel economy, especially under boost. Plug selection should follow Ford’s service specification for your model year and engine variant.
Because plug design can vary by model year and market, always verify the exact specification for your VIN in the owner’s manual or from Ford’s parts site. If you must use an aftermarket plug, select an iridium or platinum long-life plug with the same heat range and thread size as the factory plug.
OEM recommendations and aftermarket options
Before listing the common options, note that Ford typically specifies long-life iridium plugs designed for turbocharged EcoBoost engines. If you prefer aftermarket brands, choose high-quality iridium plugs that specify compatibility with Ford 1.0 EcoBoost engines and verify heat range and gap with the parts catalog for your VIN.
- Motorcraft Iridium Spark Plugs (Ford OEM specification; designed for turbocharged EcoBoost engines)
- NGK Iridium IX or equivalent iridium plugs with the same heat range and reach
- Denso Iridium TT or equivalent iridium plugs that match the factory specification
- Bosch Iridium or Platinum+Iridium equivalents that meet Ford's spec for heat range and thread size
In short, choose plugs that replicate the factory characteristics: iridium tip, long life, correct heat range, and proper thread size and gap. Replacements should maintain the ignition and combustion profile intended by Ford.
How to verify the correct plug for your vehicle
Check the owner’s manual or Ford’s official parts lookup for your exact model year and VIN. The 1.0 EcoBoost generally uses a 14mm thread with a standard reach and a pre-set gap; if re-gapping is required, use the factory-recommended gap (typically around 0.028–0.032 inches). Do not alter the electrode design or heat range beyond factory specs.
For peace of mind, confirm the specification with your dealer or a trusted aftermarket parts retailer using your VIN. That ensures you won’t run into misfires, poor cold starts, or degraded fuel economy caused by an improper plug choice.
Steps to replace spark plugs on a 1.0 EcoBoost
If you’re replacing the plugs yourself, follow these steps to ensure a proper installation and engine safety.
- Park the car on a level surface and disconnect the negative battery terminal to prevent any electrical shorts.
- Remove the engine cover (if equipped) and access the spark plug wells by loosening and removing the coil packs or ignition boots.
- Carefully detach each coil pack or boot and inspect the plug well for debris; keep track of each coil’s position to ensure correct reassembly.
- Gently clean around the spark plug wells to prevent debris from falling into the combustion chamber. Use a soft brush or compressed air if needed.
- Inspect the old plugs to determine wear and confirm the need for replacement; note the installed gap to compare with new plugs.
- Thread the new plugs by hand to avoid cross-threading, then tighten to the manufacturer’s torque specification with a torque wrench.
- Reinstall the ignition boots or coil packs in the correct order, ensuring a snug and proper fit without pinching the wiring harness.
- Reinstall the engine cover and reconnect the battery. Start the engine and listen for smooth operation; check for misfires or warning lights.
- Dispose of used plugs properly and reset any maintenance reminders if applicable.
Following these steps helps ensure a proper seal, correct ignition timing, and reliable operation. If you’re unsure about torque figures or access in tight engine bays, seek professional service.
Summary
For Ford’s 1.0 EcoBoost, the safest and most reliable choice is the OEM Motorcraft iridium long-life spark plugs. If you opt for aftermarket plugs, select high-quality iridium options that match Ford’s heat range, thread size, and pre-gap. Always verify compatibility with your exact model year and VIN, and follow proper installation practices to maintain performance and efficiency.
What brand of spark plug does Ford recommend?
Motorcraft
While Motorcraft isn't the only spark plug manufacturer out there, it's the only one producing spark plugs considered OEM for Ford and Lincoln vehicles. And remember, the spark plug is too crucial for you to gamble on its quality with aftermarket parts.
What are the best spark plugs for turbo engines?
PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.
What is the best spark plug for the Ford Ecoboost engine?
A customer of mine was able to confirm with a ford engineer the chamfer for the seal was never removed and we have tested to confirm. Our recommendation for spark plugs going for it is the same as it is for every other EcoBoost, ngk 95605.
What is the lifespan of a 1.0 EcoBoost engine?
around 150,000 to 200,000 miles
The Ford 1.0 Ecoboost engine is known for its great performance and fuel efficiency. In the UK, drivers can expect a long life for this engine with regular care. It usually lasts around 150,000 to 200,000 miles.
