what color? are they still available?

it does work, only wish it was also on the front end.

What type of fuel do you use in your xc90? I hear that 91 is recommendd but regular 87 can be used also. If I use the 87 octane am I doing any damage to the car/engine or just a lack of performance.

Has anyone else had an issue with this? I have heard on other bogs that this could be fixed under warranty. Anybody hear that? I hope so as I have 3k left before warranty is up. Also has anyone used...
