Bosch Platin FD5POR are great plugs for high boost applications. Don't know about for the V6- what are you talking about in regards to boost w/ a '96 A6? Only A6 I can think of that is turbo back in '96 would be either a TDI of some sort or the 1.8T, which is not available in the US. Course if you are outside of the US, that's a stupid comment that I made. Taka
