Intake manifold

I was replacing my spark plugs and one screw holding the ignition coil stripped while another snapped. I have change 3 plugs (the easy one) and could have more problems. I spent half a day trying to drill the screws out to no avail and also noticed the intake manifold is plastic. I was thinking of swapping it out. This would alleviate the broken screw problem and make pulling the plugs easier. It also looks like it's just 8 bolts. Would swapping a new intake manifold in add any performance gains? Is there a manifold others recommend?

I replaced mine with the Dorman unit, for the same reason. I had four coil mounts broken. The replacement is a good quality part and comes with everything needed to install it. It is a labor intensive job that I happily paid the $500 to have a shop perform. I didn't notice any performance gain from it.

Thanks, that is what I was looking for. I was looking at the dorman intake also, I think it's around $165, you found it to be good quality? NAPA near me has a plastic one and wants nearly $300 for it. I assuming you also replaced the gasket? anything else? I was going to do the thermostat, plugs, plug boots, and iac valve. I also plan on putting in a high output alternator, so was thinking I should do that too. from looking online it looks like it's about 8 bolts that hold on the intake but you have to remove a lot of tubes/wires/brackets to get to it. As well as the alternator.

My plugs were freshly changed, at the time. I replaced all the coils with Motorcraft parts, as well as the manifold. The manifold comes with the o-rings that seal it, as well as all other gaskets and o-rings and a new thermostat. It's a very complete kit. My understanding is that it's a 6-9 hour job. I didn't have that kind of time available, so I turned mine over to a shop.

Yes, the Dorman intake is plastic as well. It's a good, very complete kit. If you need to change your spark plugs, this a great time to do it. Also, if your valve covers are leaking, great time to change those as well.
