Just a few tools are required to replace the spark plugs in your car. The most crucial equipment is a spark plug socket and an extension for a socket wrench. There are two sizes available for spark plug sockets: 5/8 inches and 13/16 inches. The rubber insert included in most spark plug sockets keeps the plug firmly in place.
If it’s tough to get to your spark plugs, you could also require a universal joint. The wrench can be turned in one axis and converted into a rotation around another axis using universal joints, which are articulated joints. A universal joint might be useful if you can’t fit a wrench and extension in the area surrounding your spark plugs.
It’s crucial to avoid overtightening the spark plugs when changing them. The threads in the cylinder head or the spark plug may be harmed if it is overtightened. Make sure you don’t overtighten your plugs by using a torque wrench. The torque you apply when twisting a torque wrench is indicated via a gauge on the tool.
While the majority of contemporary spark plugs are pre-gapped from the factory, having a gapping tool on hand is a smart idea. Using a gapping tool, you can check if the gap between the ground electrode above the spark plug’s center electrode is the appropriate size. The spark on your spark plug ignites here.
A pair of boot pliers, a length of rubber tube, a clean rag, some rubbing alcohol, a tube of anti-seize, compressed air, or a wet/dry vacuum may also be useful to have on hand. Although not necessary for a straightforward spark plug replacement task, these supplies can make sure that everything goes according to plan.

What type of spark plugs are used in Hondas?
As I previously stated, NGK spark plugs are typically placed in Honda automobiles at the factory. There are Densos within several high-end versions. VTEC or not, 1.7L or 3L, and other technical parameters have no bearing on this.
I’m aware that many customers decide to install Bosch spark plugs in their Honda vehicles. I don’t really advise it because Honda, as a manufacturer, uses Japanese plugs in all of its vehicles, including the Accord, Civic, Element, Pilot, and others.
Of course, copper is the least expensive. Its mileage, however, ranges from 20 to 40 thousand miles, with an average of about 30 thousand. Iridium can provide greater than three times the mileage while costing three times as much as platinum spark plugs.
The performance doesn’t really depend much on the content. There is only one exception: if you’re running boost, iridium spark plugs are the best option. But performance is the same for common settings.
Spark Plug Socket Sizes and their Uses
Many people believe that spark plugs of all sizes are the same. But the reality is extremely different. There are various different sizes, and understanding the size is crucial to selecting the proper spark plug socket.
Despite the fact that spark plugs come in a wide variety of sizes, they are typically either 5/8 or 13/16 in diameter. The majority of newer cars, including those from Nissan, Chevy, and Subaru, as well as the majority of tiny engines found in lawnmowers and similar devices, are covered by the 5/8. The most typical place to find 13/16 spark plugs is in older cars.
Other sizes are utilized for more specialized engines, though. These include 9/16 plugs, which are prevalent in some Ford models, 18mm plugs, which are typical for motorcycles, 3/4 plugs, which are another small engine size, and 7/8 plugs, which you might find in tractors and other older vehicles.
Can I take out spark plugs with a standard socket?
Spark plug sockets do a similar task to a regular deep socket when it comes to tightening or loosening machinery.
Spark plug sockets are attached to a turning tool using a square drive socket for them to function. They can also have a hex or bi-hex head on occasion.
To loosen the spark plugs, just insert the spark plug tip into the socket head and twist.
Whether it includes a rubber insert or is magnetic, the spark plug socket will function differently depending on the sort of socket you’re using.
Do I Need A Special Socket For Spark Plugs?
No and yes. A specific socket is frequently the best tool for the job, however a standard socket should work just as well.
Spark plug location in contemporary automobile engines is extremely intricate. Some spark plugs are positioned far inside the engine and are encircled by threads and wires.
Simple spark plug replacements can be completed with ease using a standard socket. However, to reach the spark plugs without causing any damage to the wires during replacement, you’ll need the appropriate size socket with swivel handles.
Alternatively, a universal joint socket would work. Additionally, compared to standard socket sets, a universal joint socket with a magnetic or rubber insert may accommodate a new plug better.
It is best to seek professional guidance on the tools you should use for your car if you are unsure.
How To Use A Spark Plug Socket?
Spark plug removal instructions using a normal socket or a universal joint are as follows:
- Locate your spark plugs first. Look for the plug wires that surround the ignition coil, coil pack, or distributor cap. Follow these wires to the engine block, where spark plug sets are connected to them.
- Each spark plug wire should be taken out of the plugs. To know which spark plug wire goes where, you might want to mark them.
- The next step is to place your spark plug socket on top of the plug. Make sure the size is appropriate. It should ideally fit snugly around the plug without moving.
- Next, fasten the deep socket’s back with the socket wrench (or torque wrench, if you’re using one). Between the socket and the torque wrench, an extension bar can be added.
- The spark plug must now be removed from the spark plug hole by turning the wrench while holding it in place with the extension bar.
Note: You must use the same process and apply dielectric grease to the spark boot when installing a new plug. The new plug doesn’t adhere to the boot because of the dielectric grease. The socket wrench’ torque should then be adjusted in accordance with the recommended torque specification, and you’re done!
How long do Honda Accord spark plugs last?
Experts advise changing your spark plugs around every 30,000 miles to maintain the ignition system of your Honda car in top condition.
What is the price of replacing the spark plugs in a Honda Accord?
Best in Automotive Repair A Honda Accord spark plug replacement typically costs between $116 and $187. While parts are priced between $69 and $127, labor is predicted to cost between $48 and $60.
Iridium or platinum spark plugs—which is superior?
With a 700 higher melting point than platinum, iridium is believed to be six times stronger and eight times tougher than that metal. Spark plugs made of iridium feature incredibly tiny electrodes and good wear characteristics. Iridium spark plugs can live up to 25% longer than comparable platinum spark plugs because of their durability.
Iridium spark plugs include a core electrode made of a thin wire that is intended to carry electricity more effectively and improve firing efficiency.
This valuable metal comes at a cost. Spark plugs made of iridium are often the most expensive, costing between $8 and $15 each.
Which spark plugs, NGK or Denso, are superior?
While Denso manufactures strong, long-lasting spark plugs, NGK provides overall higher performance. The best spark plug brand to choose is NGK if you want to increase the performance of your engine.
Spark plugs have a 200000 mile lifespan.
If properly cared for, they can go 100,000 miles. However, after 200K, you might already be past due for a third set of plugs. Replacement cost: $100 to $300.

How do I determine the right spark plug size?
The various spark plug kinds can initially appear confusing, but the simplest approach to determine what kind of spark plug you require is to consult your owner’s handbook. The correct plugs for your car will be described in the manual.
Can a spark plug be removed without a spark plug wrench?
The spark plug is readily removed because it is attached to a rubber component in the wrench slot. If you don’t have a socket wrench, gather the following equipment for a backup plan: a flexible wrench. a plier
