The maroon airfilter is from a long stoke A7 where the rubber went straight from the carb to the filter box. When they bought out the A10 and the later short stroke A7 the carb was at different hight between the A7 and A10 so they had a right angled rubber connector to the airfilter box like the black one to allow for the height difference.
