What is the spark plug gap on a Ford 3.5 V6?
The recommended spark plug gap for a Ford 3.5 V6 engine is 0.054 inches (1.37 mm). This gap setting is crucial for optimal engine performance and fuel efficiency.
Understanding Spark Plug Gaps
The spark plug gap refers to the distance between the center electrode and the ground electrode of a spark plug. This gap allows the spark to jump across and ignite the air-fuel mixture in the engine cylinder. The proper gap setting ensures the spark has enough voltage to reliably ignite the mixture, leading to efficient combustion and power output.
Spark Plug Gap for Ford 3.5 V6 Engines
Ford specifies a spark plug gap of 0.054 inches (1.37 mm) for their 3.5-liter V6 engines. This includes models such as the Ford Fusion, Ford Edge, Ford Flex, Lincoln MKZ, and Lincoln MKX that use this engine. Maintaining this gap is important for the engine to run at its best.
How to Check and Adjust the Spark Plug Gap
- Locate the spark plugs, which are typically accessible from the top of the engine.
- Use a spark plug gap tool or feeler gauge to measure the gap between the center and ground electrodes.
- If the gap is not 0.054 inches (1.37 mm), carefully bend the ground electrode to adjust the gap to the proper specification.
- Reinstall the spark plugs and torque them to the manufacturer's recommended specification, typically around 15-25 ft-lbs (20-34 Nm).
Properly gapping the spark plugs on a Ford 3.5 V6 engine is a simple maintenance task that can help ensure optimal engine performance, fuel economy, and longevity.
What is the gap on a factory spark plug?
The gap setting is different for each vehicle but most are somewhere between 0.028" and . 060".
What is the firing order of the 3.5 L EcoBoost?

What happens if my spark plug gap is too big?
Many think the larger the gap, the better. However, if the gap is too large, and the ignition system can't provide the voltage needed to spark across the gap, or turbulence in the combustion chamber blows out the spark, misfires will occur.
What happens if spark plugs are gapped differently?
Any spark plugs that are gapped incorrectly can result in poor engine performance by altering engine combustion, weakening the ignition spark, and delaying the arcing of the ignition spark as it crosses each spark plug diode.
What is the correct spark plug gap?
between 0.028″ and 0.060″
To put it simply, the gap is the space between the central and side electrodes. This spacing is pivotal, dictating the spark intensity, which is crucial for efficient combustion. Vehicle manuals provide the ideal gap, which usually ranges between 0.028″ and 0.060″.

Which side is Bank 1 on Ford 3.5 EcoBoost?
Two is on this side. So if you have problems with something else you just hope that it says banking because it can significance injectors. Everything is a little bit easier to reach also.
What is the spark plug gap on a 2011 Ford f150 3.5 L Ecoboost?
For 2011-2014 models, The recommended spark plug gap on all tunes including stock is . 032. For higher boost tunes run the lower gap. It's also a good idea to change plugs a little more frequently than recommended in the owner's manual, especially on more aggressive tunes.
