What is the spark plug gap on a Ford Transit Connect?

The recommended spark plug gap for a Ford Transit Connect is 0.028 to 0.032 inches (0.71 to 0.81 millimeters). This gap setting is crucial for the proper functioning of the vehicle's ignition system and engine performance.


Understanding Spark Plug Gaps


The spark plug gap is 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 optimal gap size is specific to each vehicle model and engine type, as it affects the voltage required to generate the spark and the overall efficiency of the ignition system.


Spark Plug Gap for Ford Transit Connect


According to the Ford Transit Connect owner's manual and technical specifications, the recommended spark plug gap for this vehicle is 0.028 to 0.032 inches (0.71 to 0.81 millimeters). This gap setting is critical for the engine to operate at its best, ensuring proper combustion, fuel efficiency, and overall performance.


Checking and Adjusting the Spark Plug Gap


To check and adjust the spark plug gap on a Ford Transit Connect, follow these steps:



  • Locate the spark plugs, which are typically accessible from the top of the engine.

  • Use a spark plug gap tool or a feeler gauge to measure the gap between the center and ground electrodes.

  • If the gap is not within the recommended range of 0.028 to 0.032 inches (0.71 to 0.81 millimeters), carefully bend the ground electrode to adjust the gap accordingly.

  • Repeat the measurement and adjustment process until the gap is within the specified range.


Maintaining the correct spark plug gap is essential for the optimal performance and fuel efficiency of your Ford Transit Connect. Regularly checking and adjusting the gap, as recommended by the manufacturer, can help ensure your vehicle runs smoothly and efficiently.

What is the rule of thumb for spark plug gap?


Consult a recommendation list or vehicle manufacturer's handbook for individual gap settings. The rule of thumb for the spark plug gap on older engines is coil ignition 0.025 thou and magneto ignition 0.018 - 0.020 thou.



What does too much spark plug gap do?


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 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″.



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 happens if your spark plugs are gapped wrong?


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 spark plug gap for the electronic ignition system?


However, the larger the gap, the higher the voltage needed to strike the arc. This higher voltage stresses the entire ignition system - cap, rotor, plug wires. I would suggest going a little wider than the stock 0.025", say 0.030". But don't overdo it - and definitely make sure you are running Jeff S' red rotor!



What happens if the 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 is the spark plug gap on a 2017 Ford Transit Connect?


Owners manual gives the spark plug gap range as: 0.049-0.053 in.



Do NGK plugs need to be gapped?


Gapping fine-wire spark plugs
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK recommends a round wire-style or pin gauge gap tool to measure the gap.
