Re: intake manifold 1998 crown vic
We've only used the Ford OEM manifolds. We've heard that some of the others are not as well made but many people use them. Check ebay, they sometimes have OEMs cheap. One is on now starting at $95 and no bids. Not sure if it's for your model. There's nothing else that can cause problems other than maintenance items and the manifold or any other thing removed to replace it.
