When it comes to your Toyota engine, spark plugs make a big difference. A dirty, worn out or inferior spark plug can cause inconsistent firing, which may result in reduced performance and fuel economy. Toyota offers a variety of spark plugs designed specifically for your vehicle’s engine, including U-Groove, Dual-Ground Electrode, Double Platinum and even Iridium spark plugs.
Below are descriptions and benefits of these spark plugs. Please be sure to use the correct spark plug for your Toyota engine; the wrong spark plug can negatively affect fuel economy and overall performance.
U-Groove Spark Plugs
As its name implies, the U-Groove design incorporates a U-shaped 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 and original specifications on your Toyota.
Dual-Ground Electrode Spark Plugs
Select Toyota models feature the distributor-less Toyota Direct Ignition System (TDI). Introduced in 1994, this system promotes greater combustion efficiency by firing the spark plugs twice as often as a standard ignition. With that in mind, the ideal spark plug for TDI-equipped Toyotas is the Dual-Ground Electrode design, which delivers optimum performance and durability while maintaining the original recommended change interval.
