When I was riding with F5-snopro last weekend, one of the things we notices while my hood was up (F7)was this.
On the F-Sleds, there is a tie wrapped bunch of cables that come up from under the motor routing to a computer box or something (not sure what it was, I only had a few minutes to look at it)
When we opened his hood, on the F5 the cables have a corrugated plenum duct wrapped around them, on the F7 they do not. When I was dropping off the sled at dealer, we opened the hoods on the F5 & F7 on the floor. Same thing. F5 had it, F7 didn't.
Any guesses as to why? I am thinking that it would be a cheap & easy thing to put on the F7, but aside from heat protection, why were they used.
