NGK Laser Platinum Spark Plug for Audi and Volkswagen Models (2005–2018)

The NGK 1675 Laser Platinum spark plug, type PFR7S8EG, ignites the air-fuel mixture in a wide range of 2005–2018 Audi and Volkswagen models, from the A3, A4, and TT to the CC, Jetta, and Tiguan. Its center electrode carries a laser-welded platinum tip, and a platinum disc is welded to the back of the ground electrode. NGK credits those dual platinum surfaces with a slow wear rate, long service life, stable idle, and resistance to fouling. Trivalent metal plating on the shell resists corrosion and seizing. NGK rates the plug as OE quality, and this version is made in the United States.

This NGK spark plug carries a 24-month or 24,000-mile warranty.

Audi and Volkswagen have used several part numbers for this plug over the years: 101905631B, 101905631H, 06H905611, and 06H905601A. If the plug coming out of your engine carries any of those numbers or NGK PFR7S8EG, this is the matching replacement. A spark plug fires the coil's high-voltage pulse across its gap to start combustion in each cylinder. Because the applications cover so many models and trims, the fitment table below is the place to confirm yours.

Common Questions

What does the platinum disc on the ground electrode do?
It gives the ground side a platinum firing surface to match the center tip, which NGK says slows wear and extends plug life.
