Spark Plug Denso Iridium IK22 5VZ 3.4 Liter (Sold Each)
These 2 step colder plugs are recommended by URD if you are running the 7th Injector upgrade on a Supercharged 5VZ engine.
If you are running the stock pulley (Low Boost) on the 5vz supercharger, Magnuson recommends staying with the stock heat range spark plug.
IRIDIUM POWER! A new generation of high performance spark plug that uses the worlds smallest Iridium electrode that is a mere 0.4mm in diameter! The smaller the electrode, the more concentrated the electric potential at the electrode. The stronger the electric field, the lower the required voltage. As a result, combustion is good for all types of driving, the engine starts easily, and acceleration improves.
6 are required for the 5VZ
