NGK SPARK PLUGS Spark Plugs Laser Platinum Spark Plug PZFR5F-11

Laser Platinum® spark plugs provide high ignitability and longer service life with laser-welded dual platinum surfaces.

Laser welded dual platinum surfaces are designed for a slow wear rate providing a stable idle, anti-fouling properties, improved fuel efficiency, and lower emissions. This OEM-approved design provides durability for a longer life and quicker acceleration.

These are resistor-type plugs designed to reduce Radio Frequency Interference (RFI) or electrical “noise” that can cause interference with the operation of radios, electronic components, fuel injections systems, depth finders and other sensitive electronic equipment.

Key Features

• Laser welded platinum center electrode tip and platinum disc for a longer service life
