I was able to change the spark plugs in my 1999 Toyota Solara with the 1MZ-FE 3.0L V6 thanks to all the assistance on this site.
I was easily able to reach around the intake plenum to get the back plugs, and it only took me about three hours (including taking pictures and videos). The next time, I could likely finish in less than an hour.
Accessing the middle rear plug proved to be the most challenging because my 6″ extension did not fit under the plenum. To reach it, I used a UV joint with a 3″ extension and a 1″ extension.
Here is a quick how-to video I made:
Here are some images captured during the procedure:

Behind the intake plenum/throttle body assembly is an easily accessible rear plug (#5 on the driver’s side):
Remove the old plug and the ignition wires. With a ratchet obtained from the region behind the throttle body, replace the replacement plug #5. Use a 3/8″ drive ratchet with a 6″ extension plus a 1″ extension and a 5/8″ spark plug socket.
By removing the PCV valve hose and this ground wire, you can access the rear plugs (#1 & #3, passenger side and middle) from the passenger side of the car:
The #1 and #3 plugs are clearly accessible once the ground wire and PCV valve have been moved out of the way.
The 6″ extension on the 5/8″ spark plug socket can be used to install plug #1 on the passenger side.
A universal joint will be required to snake a 3″ extension with the spark plug socket down into the hole for the rear middle plug because a 6″ extension won’t be able to clear the plenum.

What is the most effective tool for removing spark plugs?
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.
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!
