Review on Spark Gasket 12342 P08 004 Automotive Replacement by Lukundo Lim

3 of these were needed to replace the valve seal (my mistake) as I used a flathead screwdriver to poke holes in these rubber seals to get them to seat in their sockets. I didn't notice until I checked the spark plug tips and they were covered in oil. Not smart. Turns out all I had to do was lubricate the perimeter of these seals with black car grease before installing, and they slide in easily with a simple finger press. No hammers or blunt objects. Just a tip for those who are taking on this job and don't want to order new replacement seals in the future. They feel and fit just as well as the OEM seals. A good thing.
