manifold

So this is posted ...somewhere "GT style explorer intakes $100 upper and lower GT40p heads complete, need refreshed $100/set" I have a 89 HO. I know the HO manifolds and heads are better than the 302 and the Explorer parts work great on a 302. But how much better are they than HO parts? Is it...

Does this look like a ground? 2003 mustang GT. Replaced intake and now reverse lights,speedo, and blower motor is out. Could this have something to do with it? The wire is only about 5-6 inches long and literally nowhere to plug up. Any ideas?

2004 gt, factory intake manifold, this bolt hole behind the throttle body towards the passenger side, goes into the plastic manifold, what's it for? Just wondering if somethings supposed to go there. (In the photo it's the hole with the brass sleeve there, between the TB spring and cable)

I come from fox bodies, so I'm new to the 4.6. I'm wondering if my 04 has the upgraded manifold? Under load on the freeway it gets a little bit of shaking like its motor mounts, but it seems solid at idle, any ideas what it could be? Heres some photos of my manifold. Thanks

So I have a rattle when my 2001 mustang is turned on sometimes and sometimes when I put it into gear. After I’ve driven it for a while and it’s warmed up, the rattle goes away. There is an exhaust leak from where the manifold and the exhaust pipe meet on the passenger side. Could this exhaust...

I somewhat recently purchased a cobra upper and lower and will soon get around to installing them. As my car is a daily driver I am trying to sort out any issues beforehand. I know this is a common swap so I'm sure some of the information I'm asking for is out there I'd just like to be certain...

I am looking for a GT40 upper and lower intake and there are several on eBay. What should I be looking for? Is there a specific year? So many options, I need a little guidance.

Going to be removing my passenger side exhaust manifold due to it being cracked completely in half right above where the flange connection is, managed to remove the 6 nuts fastening the manifold to the block , and the top egr bolt, but I can't seem to reach the lower egr bolt or the two bolts...

Hi all, I am getting ready to swap out my busted 96 4.6 sohc engine with an identical one in the next week or so. (Been struggling with a stubborn midpipe bolt.) Anyway I've been reading today about a common problem with these plastic manifolds leaking coolant and eventually cracking. This new...

I have coolant pooled up under my upper intake manifold near my passenger side valve cover. I recently replaced my thermostat and have a coolant sensor that I still need to put in. I can't tell if it's leaking from a cracked manifold or if it's a bad intake gasket. Which is more likely and how...
