Not sure if anyone here wants to sign up to have Edelbrock test fit parts on your car, but it could be a step in getting more aftermarket support from an American parts company, something we need, 'cause we all know the Euro tuner companies just want to empty your wallets. Here's the link: http://www.edelbrock.com/automotive_...s_needed.shtml

I don't see any XF's on their list but who knows, you might have to write to the R&D guys, which I'm sure they wouldn't mind taking a few measurement and what not.. here's the application form http://www.edelbrock.com/automotive_...eeded/form.php

If anyone here is serious, I will talk with one of the R&D guys that I know over there. I would offer up my car but it's my daily driver and 3-5 days for Edelbrock to hold the car is too long for me.
