Adding a photo of the fitment with the largest H6 battery the tray accommodates. As mentioned before, I re-used the blanket from the 5H. The fitment is snug but it goes all the way around. I just disconnected the corner slot on the blanket, the end actually touch still and secured the blanket with restraint zips all the way around. Somewhat hard to tell but I'd say there is a good .5" of space between it and the filter housing and 3/4" of space between it and the primary intake tube.
Hate to bring up an old thread, but I see in the beginning it was mentioned someone with a GTI had an issue with fitment and I cannot find the thread anywhere. Does anyone have any information on that??
