Ok I've opted to NOT install this intake. I pulled everything and my zenith is a 11147 model as shown in pics below. Is this bolt supposed to be there? ... sure doesn't look right. Also I can't get intake separated from exhaust manifold because of this 1 crazy looking bolt. .. doesn't look like the rest?
