Spark Plugs

Genuine Toyota Spark Plugs are designed to maintain optimum vehicle performance and durability. Toyota offers many different types of spark plugs designed specifically for your Toyota vehicle.

Always use the right spark plug for your Toyota - the wrong spark plug can negatively impact fuel economy and overall performance.
U-Groove Spark Plugs

This spark plug features a special groove in the middle of the ground electrode. Before the spark plug fires, the U-Groove traps the fuel-air mixture, then produces a large spark for efficient combustion and reduced fouling. U-Groove spark plugs meet original equipment replacement intervals, comply with the original specifications on your Toyota, and offer strong throttle response and smooth idle.
Dual-Ground Electrode Spark Plugs

Select Toyota models feature the Toyota Direct Ignition System (TDI), which enables spark plugs to fire twice as often. The system, introduced in 1994, creates a more efficient and cost-effective engine. Dual-Ground Electrode Spark Plugs feature a special design that delivers optimum performance and durability while maintaining the original recommended change interval.
Double Platinum Spark Plugs

Genuine Toyota Double Platinum Spark Plugs are recommended for select Toyota models, and feature several benefits:

* Platinum on the center electrode and ground electrode reduce wear while providing a long service life of up to 60,000 miles.
* The raised design provides excellent ignitability for a strong spark, translating into a smooth idle and strong performance.
* Nickel and iridium are added to the platinum, resulting in an alloy that helps make the Genuine Toyota Double Platinum Spark Plug strong and durable while helping to prevent cracking.

Iridium Spark Plugs

Toyota recommends Iridium spark plugs for select Toyota models for the following reasons:

* A smaller center electrode promotes higher performance.
* Iridium is a more durable than platinum with a melting point that’s approximately 1,200° F higher.
* They last longer than conventional spark plugs. (Up to 110,000 miles.)
