The "cheap" plats in Audrey run for a year, without problems. I think all
the plugs troubles are for turbo cars. Couple of questions...


1. How would I tell "cheap" from "expensive" Bosch plats? Does such an
distinction _really_ exist? What if I just ask to be overcharged? *S*

2. What is the part number for the cheap ones, and for the expensive ones?

3. Have any of you turbo owners tried the  Plat +4's yet?
