Catching up on my Roundel reading, I noticed in the February Tech Tips article that Mike Miller says the Performance Package camshafts are sourced from Alpina.

True or false? I'm skeptical. None of the BMW literature for the ZHP mentions Alpina, and one would think that special Alpina cams would be a selling point for enthusiasts.

If it's true I wouldn't be surprised. The X5 4.6is uses the engine from an Alpina B5 (I think). BMW doesn't exactly "hype" their relationship with Alpina.
