"I'm all for improving factory designed stuff but it's an oil cap. If it seals well and does not leak it's doing it's job."
The theory behind the fins and aluminum design was lower oil temperatures... obviously that did not fulfill its designed function and now the community knows because folks went out and tried it for a long period. Anyone can make a cap that doesn't leak. If people bought the new design thinking it would be better at not leaking, then obviously they missed the point and wasted their money.

Only reason I can see using this was what was explained above because the stock BMW 'tool' for removing the oil filter housing will no longer fit well with certain aftermarket intake manifolds. I would still argue to just use a different oil filter wrench and be done with it vs. spending $65 bucks. Or just modify the stock tool so it will fit with a hacksaw if there is only one area with a clearance issue.
