How Many Spark Plugs Does a 5.0 Mustang have?

The required number of spark plugs directly depends on engine cylinder specs. In fact, almost all vehicle models include the same number for cylinder & spark plug.

Likewise, the majority of L Mustang features V8 versions. Therefore, you’ll have 8 functional cylinders. And the exact replacement calls for 8 spark plugs, one for every cylinder.

How to Change Spark Plugs for 5.0 Mustang?

Setting a spark plug isn’t exactly a hard task to pull off. You can easily attend the process, knowing the involved parts. Then you should check out the system by yourself for saving the garage expense.

#1. Drive the engine to reach normal operating temp. Let it get cooled to hit a comforting level.

#2. Take out all the dirt/debris surrounding coil-on plugs. Utilize compressed air and clean cloths.

#3. Identify the negative battery terminal inside the mechanism. Carefully disconnect the terminal.

#4. Remove all sorts of electrical connections from the plugs. Remain cautious for an individual plug.

#5. Gently press the top-left tap on the plug. Pulling the system will release the integration of plug & coil.

#6. Locate the joining bolt to the right of each coil. You’re to check out 8 bolts in total for Mustang.

#7. Pull up the entire assembly to wiggle from left to right. It should help with the removal of seals.

#8. Better apply a liquid penetrant to sit for 15mins. Start loosening the plugs with wrench & socket.

#9. Gently take out the plug from the individual cylinder. Try to maintain a lined-up socket with the plug.

#10. Install the new plugs through a built-in thread. Using an anti-seizing agent will ease future removal.

#11. Start reinstalling all the coil packs. You’re to follow the reversed order of steps 4 – 7 above.

#12. Reconnect the negative battery terminal to complete the setup. Go for a test drive to get the result.

Don’t forget to check the mechanism for any sort of leftover. Carefully take a look at the entire system before closing the hood.

Importance of Proper Heat Range of Spark Plug

Right heat range comes with extreme importance to retain effectiveness. Before anything else, satisfactory heat can get the plug life extended. Proper heat range helps with the optimization of spark to initiate consequent ignition.

When it gets to the heat range, two terms are inevitable to encounter. You’ll have to make the choice between Cold Spark Plugs & Hot Spark Plugs.

Not to mention, heavy engines like the 5.0L Mustang will definitely require cold ones. You better continue reading the sections to get a clearer idea of the distinctive categories.

Poor heating concerns with carbon buildup to clog the internal parts. Also, an extremely heated plug leads to premature donation right into the burning chamber. And it eventually takes down the engine’s overall performance.

How can I Identify a Spark Plug’s Heat Range?

Identifying the heat range isn’t the same with every model. Of course, there are some indicating spec comes with the model to reveal the range. But the ratings vary in terms of appearance. In fact, different manufacturers utilize different indicating patterns.

NGK spark plugs come with simple numbering to rate the heat dissipation. You get to choose from 2 – 11, concerning the thermal characteristics. Lower number means hot spark plugs, ideal for low-powered engine systems. But cold spark plugs come with higher numbering, remaining ideal for high-powered engines.

Meanwhile, Denso integrates numbered indication in a different way. The lowest one measures 9 while the highest number reaches 35. Likewise, the lower number depicts hotter plugs against highly numbered cold spark plugs. It’s more like 9 – 35, but the increment of numbers is abrupt in nature.

There are several other manufacturers with numbered indication. You may take Champion, Bosch & Pulstar into account. Champion plugs are absolutely random to define the range, in terms of numbering. And Bosch gets it in reverse order – lower numbers revealing colder plug mechanism.

Therefore, you’ll have to take care of the factor by yourself. It’s certainly one particular option not to neglect. You better contact the seller/manufacturer prior to make the purchase. Unless you get yourself one pretty cheap aftermarket crap, you’re to find a satisfactory answer.

Frequently Asked Questions (FAQs)

Question: How often to change spark plugs wires?

Answer: The thumb rule calls for a change every 60000 – 100000 miles of running. But several high-quality plugs require replacement after 30000 – 40000 miles.

Question: What happens if you don’t gap spark plugs correctly?

Answer: Improper plug gaps lead to affect the engine function negatively. Roughness, misfire, hesitation, knocking, poor startup – certain symptoms to encounter.

Question: How often do you need to change iridium spark plugs?

Answer: Iridium plugs come with extended change intervals. The range of intervals usually remains within 60000 – 10000/150000 miles of the engine running.

Question: Do better spark plugs increase horsepower?

Answer: It’s possible to get some increase in horsepower, by only 1% – 2%. And you can attend the increase only having the absolute perfection in replacement.

Question: How do you know if a spark plug is too hot?

Answer: The surface gets exposed to combusting gas upon extreme heat. Slower dissipation of heat causes the firing end to experience a faster temperature rise.

Question: How to measure the spark plug gap without a tool?

Answer: Keep tapping the plug against its surface to readjust the gapping distance. Continue gradually with intense care unless the gap comes into size.

Question: What’s the difference between hot and cold spark plugs/What makes a spark plug hot or cold?

Answer: Cold ones come with shorter insulator nose, initiating rapid heat transfer. Unlike the cold ones, hot spark plugs go well with low RPM engine systems.


The seemingly simple mechanical tool comes with extreme significance for any vehicle. Compromising with its quality will merely meet your expectation regarding engine performance. And you can count on the comprehensive best spark plugs for 5.0 Mustang reviews.

Among the enlisting, you better get settled down with New Motorcraft SP519 Spark Plug. There are several good reasons to get it in the first place. Quality, efficiency, performance, fitment – everything seems to match the calls. And the demanded price is definitely worth every penny.
