Well, I think I might have the same duct. My RV-7 was built in '04 and I'm the second owner. It has the IO-360 with a forward facing intake using a fiberglass duct that goes up to the bottom of the air intake on the left side of the cowl. I think it looks great with the smooth bottom cowl. I've not noticed any cracks yet. I'm at 280 hrs. Will keep a lookout.
I do wonder if that is the best sort of arrangement, though. I don't think I get enough MP and TAS. (Are we ever satisfied?)

[quote] RV8a intake duck splits at the seams on both side.
I have a RV8a completed in 2002 and am on my second problem with my Air intake . I have the type that picks up fresh air on the left side of the cowling next to front mount prop governor (not in the center below the prop). Here is what happened this time during my condition inspection, I notice a crack on either side of the fiberglass duct that takes the intake air to my Bendix servo. I removed the fiberglass duct to find it was originally made in two pieces and was glued together. Well so much for the gluing process, it has literally has come apart at the seams.
I was wondering if any one else has had this problem?
If not please check your own intakes at about 375 hours. I have one of the first quick build kits to come off the boat and I am not quite sure where the fiberglass parts are made? My RV8a is a tightly cowled around IO-360 and the intake duct did rub on the lower cowl at shut down . I have cut out some of the S-Glass to make a little more clearance.
Just and FYI if you have my type of air intake

I haven't flown my -7 yet, but after hours of re-modelling the intake and giving it a nice paint job, (it was too wide and the intake had to be rotated 90 deg) I accidently dropped it while trying to mount it. Lo and behold - it split both its seams! Popped open all along the glued surfaces! The later kits have far superior ducts now and they just about fit as well!
