Does Toyota use iridium spark plugs?

Does Toyota use iridium spark plugs?
Yes, Toyota does use iridium spark plugs in some of its vehicles. Toyota Genuine Parts Spark Plugs are the exact original equipment manufacturer (OEM) part that the vehicle came with, and they are designed for an exact fit. These spark plugs are made with iridium, which offers extreme ignitibility, improved throttle response, and superior anti-fouling. Additionally, OEM Toyota plugs either have a platinum tip (90k mile lifetime rating) or an iridium tip (120k mile lifetime rating).
It’s important to note that Toyota specifies a longer replacement interval for iridium spark plugs, typically around 120,000 miles, compared to other types of spark plugs. This indicates that Toyota recognizes the durability and longevity of iridium spark plugs in their vehicles.
In summary, Toyota does use iridium spark plugs in some of its vehicles, and these spark plugs are designed to last for an extended period, typically around 120,000 miles.

How long do Toyota iridium plugs last?

Spark plugs come in three basic types: Iridium plugs, which can go 100k+ miles before requiring replacement (available on select Toyota models) Platinum plugs, which can go 50-60k miles before requiring replacement (available on select Toyota models) Copper plugs, which can go about 20k miles.

Are Denso iridium spark plugs better than NGK?

Denso plugs are installed on almost every automobile model manufactured in Japan. The iridium used in them has a superior hardness. The electrode’s diameter in these plugs shrinks more than an NGK. For this reason, Denso plugs won’t last longer than NGK units but they will be better at producing powerful sparks.

Are Denso spark plugs iridium?

First Automotive Plug to Use Iridium!
Properties of DENSO’s patented Iridium alloy have broken through the spark plug technology barrier. Employing a revolutionary new 360° laser-welding process, DENSO has created a spark plug unlike anything on the market today.

What spark plug is better NGK or iridium?

Iridium spark plugs are better at starting engines than other types of spark plug because the spark is highly concentrated in the central electrode, and consequentially requires less voltage to operate. This makes ignitions faster and more reliable, and also reduces power consumption.

Can I use NGK instead of Denso?

NGK and Denso are both fine plugs. Toyota uses both brands in manufacturing. On the V6, sometimes you see one bank with Denso and the other with NGK. IMO, get which ever one costs less because you won’t notice any difference between the NGK and Denso.

Do iridium spark plugs increase horsepower?

The spark plug manufacturers are unanimous about the fact that iridium spark plugs can considerably improve the engine power. The advantage is crucial when you need to navigate through difficult driving situations or climb steep slopes.

What are the best brand of spark plugs for Toyota?

I have bought and have used NGK iridium spark plugs in the past and believe they really improved my other, older Corolla. Really can’t go wrong with either brand. Any difference you’ll never feel. 3rd gen 4runners came from the factory with NGK on one side and Denso on the other…

How often do you change spark plugs on a Toyota iridium?

Typically we have found you can expect 50-80k miles on a traditional iridium plug.

What are the disadvantages of iridium spark plugs?

In its raw state, iridium is brittle and difficult to work with, and global production of iridium is less than 7,000 kg. The reason businesses go to the trouble of using iridium in spark plug construction is the metal’s unique combination of extreme toughness with conductivity and electrical resistance.
