70 Z Dual Snorkel Air Cleaner Day Two Modification Has anybody previously seen this modification to the stock Z air cleaner? I have seen one other air cleaner that was modified the same way, but that's it. The quality and the accuracy of the holes suggests that it was stamped- not drilled-which could have been done professionally, but that is only a guess on my part. Anybody have any clue? Thanks in advance for the feedback. Admin-I don't know if this is in the right sub forum, so if it should be somewhere else, please move it.
