Genuine Toyota Spark Plugs
Genuine Toyota Double Platinum Spark Plugs
Some non-conventional Toyota platinum spark plugs only have platinum on both the center electrode and on the ground
electrode (that’s why they’re called “Double Platinum”). This design reduces wear while providing a long service life of
If you take a close look at Genuine Toyota Double Platinum Spark Plugs, you’ll notice that the center electrode has a raised
design compared to some non-conventional Toyota single platinum spark plugs. The raised design provides excellent ignitability
for a strong spark…translating into a smooth idle and strong performance.
Also, some non-conventional Toyota platinum spark plugs rely solely on platinum; Toyota adds nickel and iridium to the platinum.
This alloy helps make the spark plug strong and durable, while helping to prevent cracking.
Genuine Toyota Iridium Spark Plugs:
The Long-Life, High-Performance Spark Plugs
In today’s world of high performance automobiles, not all engines are created equal, and neither are spark plugs. That’s
why Toyota created these special Iridium Spark Plugs to meet the needs of high-performance engines (available for select
These spark plugs feature a smaller center electrode, which translates into higher performance and meet platinum spark plug
replacement intervals of 60,000 miles.
Iridium is a more durable material than platinum (its melting point is approximately 1,200° F higher than platinum).
Genuine Toyota Dual Ground Electrode Spark Plugs
Select Toyota models feature the Toyota Direct Ignition System (DIS). Introduced in 1994, this system created a more efficient
and cost effective engine for Toyota owners. It’s also more demanding on spark plugs.
With this system, spark plugs fire twice as often — accordingly, a 30,000 mile non-conventional Toyota spark plug may only
last 15,000 miles (that means twice as many tune-ups). Toyota created a special dual ground electrode spark plug that delivers
optimum performance and durability for DIS-equipped Toyotas.
Genuine Toyota U-Groove Spark Plugs
For Toyota engines that require conventional spark plugs, we offer Genuine Toyota U-Groove Spark Plugs.
Instead of a rectangular ground electrode, U-Groove Spark Plugs feature a special groove in the middle of the ground electrode
(hence the name “U-Groove”). With this design, when the spark plug is fired, the U-Groove traps the gas and then produces a
large spark for efficient combustion. The U-Groove design also helps prevent fouling.
