My 2004 LX Camry V6 was a brand-new purchase. It has 125K miles on it right now and appears to be running smoothly. When I took it to the dealer to get the oil changed, the service advisor indicated that my Camry needed new spark plugs. He assured me that it wasn’t seriously beyond due, but he also pointed out that coils cost approximately $250 per cylinder and that if a plug went bad, it might ruin the entire “coil.” I’ve never heard of this, so I’m curious if it’s true and how likely it is to happen if it is. He gave me an estimate of $600 to replace the plugs.
He had a list of extras when I picked up the car, including the customary cabin filter, air filter, and back “tag” lamp. He noticed a more substantial oil leak at the bottom pan gasket and an oil leak around the timing cover (the belt was changed by the same dealership about 7 years ago at about 80K miles). Because debris could enter the oil pump and jam it, he suggested that the pan gasket leak was more serious than previously thought. That has never occurred in my knowledge.
Anyone have an opinion on the following?
How crucial is changing the spark plugs? Car appears to be functioning smoothly. Is $600 a reasonable price, and would the coil truly be destroyed if a spark plug fails?
Anyone anyone hear of a failing pan gasket allowing dirt to enter the oil pump?

How frequently should Toyota update its spark plugs?
Spark plug service is a crucial component of the suggested maintenance program for your vehicle, regardless of whether you drive a Toyota Highlander or any other type. As a general rule, auto experts advise changing spark plugs every 30,000 miles, although a number of conditions may make them wear out more quickly.
How can I tell if I need to replace my spark plugs?
7 Indices That It’s Time to Change Your Spark Plugs
- Starting the automobile is difficult.
- The engine stalls out.
- More frequently, you’re stopping at the gas station.
- The idle of the engine is noisy and harsh.
- Your automobile has trouble picking up speed.
- When driving normally, the engine is rather noisy.
- Your check engine light is illuminated.
Which spark plugs work the best?
- Best Spark Plug Overall: Original Equipment AC Delco.
- Best All Around First Runner Up: Denso Iridium TT.
- Best Performance Spark Plug: E3 Diamondfire.
- The best standard spark plug is an NGK.
- Best Spark Plug for Small Engines: Champion Copper Plus.
How long do Toyota spark plugs from the manufacturer last?
- Iridium plugs, which last more than 100,000 miles before needing to be replaced (available on select Toyota models)
- Platinum plugs, which last for 5060 thousand miles before needing to be replaced (available on select Toyota models)
- Copper plugs, which have a 20k mile range
However, spark plug longevity isn’t only based on the plug’s design. It depends on the fuel, the timing of the engine, and the condition of the ignition system. You might now have a poor set of spark plugs in your car if you only use mileage intervals to gauge when to change your plugs.
The concise response to the query How Long Do Plugs Last? is basically: It varies. (Read more here about replacing spark plugs.)
Should the battery be disconnected before changing the spark plugs?
When trying to replace the spark plugs in their car, this is a common query that individuals have. The battery does not need to be disconnected in order to replace the spark plugs, is the response. You may just detach the spark plug from the engine and then remove the spark plug wire from it.
Additionally, when working on anything electrical, it’s crucial to disconnect the negative connection of your automobile battery. Any mishaps will be less likely as a result. Before changing your spark plugs, make sure the engine of your automobile has completely cooled. By doing this, it will be simpler to remove the plugs and the ignition coil boot or spark plug wire.
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.
Spark Plug Swivel Socket With Extension
A socket wrench that can twist the spark plugs inside the engine is required to remove old spark plugs. You need an extension for your spark plug socket because it can be challenging to remove an old plug at times.
If you can’t find that, acquire a spark plug swivel socket instead, which can lock in and fit into small areas for quick spark plug replacements. This spark plug socket set can handle sensitive spark plug threads and is perfect for plugs with a rubber insert.
Remember to blast pressurized air around the ignition coil and old spark plug before removing it. This keeps dirt and other debris out of the plug hole.
Flexible Handle Ratchet
Spark plugs in contemporary engines are frequently installed in small, confined areas. Use a handle ratchet if a swivel socket is ineffective.
Even better, you can use a ratchet with a flexible handle in conjunction with a swivel socket wrench to turn the spark plugs.
Spark Plug Boot Puller Pliers
In contemporary COP systems, the spark plug’s “boot” joins the ignition coil and the plug. After some time, the boot may become stuck to the old plug. You must handle it carefully because some spark plug wire surrounds it as well.
Long-tipped boot puller pliers can gently remove the spark plug boot without causing any spark plug wire damage.
Spark Plug Gap Gauge
You should definitely get a spark plug gap tool since maintaining the spark plug gap is essential to keeping the plugs functional.
You have two options when choosing a spark plug gap tool: a spark plug gap gauge or a feeler gauge.
The spark plug gauge makes it easier to achieve the proper distance as required by the specifications by gapping the plugs either outwards or inwards.
The spark plug gap gauge just has to be inserted between the ground electrode and the center electrode. The electrodes should then be adjusted by carefully sliding the spark plug gauge toward the gauge’s mark indicating the required standard.
A feeler gauge can also be used to determine the spark plug gap more precisely. A feeler gauge, as opposed to a spark plug gauge, may work with delicate metals like iridium spark plugs.
Torque Wrench
To prevent engine damage and other issues, a new spark plug needs to be torqued properly. The cylinder head can be ruined by overtightening the plugs with the spark plug wrench, but loose plugs may simply fall off after a few uses.
An effective torque wrench is useful in this situation. You can use the spark plug wrench to tighten the new plug set while consulting your manufacturer’s instructions.
Wire Loom Spacers
In ignition systems where the current is carried by a spark plug wire, wire loom spacers are used to stop cross-firing and arcing-to-ground. These aid in separating the ignition wires and stop misfires, which can impair engine performance, oil consumption, and gas mileage.
How much time does it take to change spark plugs in a V6?
Fortunately, replacing a spark plug in a four-cylinder car only takes approximately an hour. The procedure can take at least an hour longer for V6 engines.
Although it may seem much simpler to leave our automobile in the hands of a mechanic, doing the spark plug replacement yourself can save you over $100 in labor costs alone.
