How to choose the correct set of spark plugs for your Ford F150?

Spark plug quality affects the performance of your car by giving poor mileage, noisy engine etc. Low quality spark plugs can cause more damage than you would like for the price you’ll pay. Along with the quality you must keep a few factors in mind when buying a spark plug for your Ford F 150. Let’s see what the materials the spark plugs are made of first.
The types of spark plugs:

Iridium

Perfect for modern vehicles because of its resistance to higher temperature thus providing better combustion for the engine with greater mileage and boosting the power of the engine. Iridium spark plugs will last longer with high durable platinum which is the ultimate choice for those looking for the best reliable long lasting spark plugs.

Platinum

With a small electrode in the center for better conductivity which in return decreases the amount of voltage needed to generate the spark; the platinum spark plugs are said to have longevity and better combustion rate then the standard copper spark plugs. There are two types of platinum spark plugs: a single platinum and a double platinum spark plugs.

Copper

The oldest and most common spark plugs currently used by engines are copper plugs. Which with time is slowly becoming obsolete spare parts. The older motors are recommended to use the copper spark plugs, the newer models tend to opt for either iridium or platinum spark plugs. This is because copper is a softer metal alloy which requires greater amount of voltage and won’t be able to take the pressure and abuse of time like the other metal alloys.

That is why the recommended spark plugs are either platinum(double or single) or iridium for your Ford F150.
Things to keep in mind while buying spark plugs for Ford F150

Now you know a little bit more about the types of spark plugs there are, let’s find out what are the main things to keep in mind before you make up your mind to buy a set of spark plugs for your Ford F150.

Gap

Spark plugs are designed for specific engines; they come pre gapped to fit perfectly in the cylinder head. As you should always make sure if the gap is measured correctly, check if the gap is precise for your Ford F150.

The gapper tool can be used to determine if you have received the correct spark plug. Ford F150 uses 0.035”- 0.045” gap size spark plug so adjust the gap if you see any discrepancy. This is done so that you can use the plugs for a long time and you won’t suffer from any significant amount of power drop.

Size

If the plug doesn’t fit perfectly in your F150 engine then it won’t be of any use. The spark plug needs to be the correct fit in the cylinder head. The reason behind this is that if the spark plugs do not fit perfectly then the previous problems will persist.

There are different sizes of threads and they are 10mm, 12mm, and 14mm. Choose the one that meets your needs. And by comparing with the owner’s manual you can determine which size will be the perfect fit for your F150’s engine head.

Quality

Getting premium quality spark plugs can improve your engine’s fuel intake and you can go faster as well. Buying quality spark plugs will also reduce the amount of time in servicing and maintenance, allowing you to drive in peace for longer and smoother. As different engines use different types of spark plugs this is why quality matters more than the brand.

The kit

As different types of engines use different amounts of spark plugs you should always be extra vigilant when ordering them. Check how many spark plugs your engine head needs and order accordingly.

FAQs

How often should the spark plugs be replaced?

Generally if cleaned and kept in good condition then the spark plugs can provide service for more than 30,000 miles. But as a rule of thumb you should check with the owner’s manual or the manufacturer just to be sure. The time of change also depends on the type of spark plugs being used.

What is spark plug gapping?

The gap between the two electrodes is known as the gap. Each engine has specific gapping so when installing you must make sure that the relevant gap is there for the electrodes to work with your Ford F150. You need the gapper tool when making the precise gap.

What will happen if the gap in the spark plugs is not correct?

For the spark plug to ignite the fuel in the engine it needs an efficient amount of voltage. If the gap is not even or specific to the engine then the motor will not run as efficiently as it is supposed to.

How would I know that I need to replace the spark plugs?

You should replace the spark plugs when your engine takes a long time to start and when it starts it starts with a shudder that leaves the whole car shaking. Or the engine is constantly misfiring and with gasoline smell when the engine is in idle. These are clear indicators of overused spark plugs in desperate need of new ones.
