I, recently saw a kit offered for sale. I remember it had an alternate air door capability and a circular air filter. Can someone send me in the right direction.
Van's FAB for the forward facing induction has an alternate round inlet. It's a safety feature in the event your primary inlet gets blocked. The builder cuts the hole and you epoxy the door onto the unit. You attached a push/pull cable located in the cabin. I believe there had been issues in the past where the primary inlet could get blocked when flying in snow. I installed the door even though we don't get snow here in FL.
