    They're a problem to find since the part changed. The green ones are too fat. I got the one that worked on my 2003 530i from amazon: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

    Just order it from GAS. Choose one of the three, they’re all good, the Viton is great, the flourosilicone is best. Original DISA. Alves had no o-rings. The gasket was molded in with the plastic housing, you have to cut it off.

    I just was a dreaming of dropping a ford ecoboost 4 cylinder into one of those rides. 300 hp and ton of tq. They make transmission adapters to fit the zentith transmission to the engine now ! Light front end and lots of power and then ya have tire smoke.

    Hmmm, you’re the second person to bring this up this month. Can’t remember who was talking to me about it. My nephew Ben got himself one of those Ford Focus RS’s, 350hp out of the box, he’s already tweaking it with bigger turbos, bigger intercooler, headers, chip, already at 450hp, has not even turned the boost up that much yet, I think he’s gonna end up blowing the thing up, but if he doesn’t, hell, I was thinking of finding a wrecked one some day! But I like my inline six’s!
