What make and model should I say to get one if I can?
42196

It pooled by the spark plugs. I cant think of anything else it might be. The temperature was far from being hot though according to the guage. I just want to drive and enjoy this thing already. This is annoying.

Okay, thanks for the info. I guess as a pro I will be doing an upgrade a lot sooner than I thought.

If you are interested in upgrading to 02 Mustang Airbox, tube, MAF, TB, and all the brackets, hoses, cables and gaskets to do it, PM me.

We recently acquired a DOHC for a swap, and will not be needing the above parts unless I also decide to PI swap the OEM npi engine that came in the car.

Will that push the car over to needing a tune? About how much hp would that even gain? I seem to remember reading that if you change the MAF sensor you need to tune the car. The goal is 300 hp so I will definitely need it at some point. I will send you a message.

There is already a running thread on this same subject, but: does the M-9424-P46 have an actual heater hose port at the right rear corner of the manifold for the T-Bird? It appears to in the pics. The video of the guy drilling and tapping the plastic blind hole on an Explorer manifold is ridiculous. I guess you could have a poll for when an already well-known trouble spot would fail.

Also, if you wanted to swap the alum crossover - are the o-rings even available? No way I would swap that unless they were. I don't need to, I have a tap. But just curious.

I dunno if those are available since the whole manifold is considered one part. I suppose if they are round you could try to match it up. I would buy a tap before trying to match up o-rings by size and material.

When I did my PI swap, I took apart the aluminum crossover and reused the original O-ring. However, I also added gobs of RTV Black to the exterior edges of the O-ring because the condition of the O-ring looked questionable to me. It's been working fine ever since.

The O rings wont be any less new on the new intake when you swap crossovers. It doesn’t hurt them to remove it, I take the crossover off regardless since it’s much easier to drill and tap for the sensor on a drill press with the rest of the intake out of the way. Keeps any stray aluminum shavings away too.

But yes, the M-9424-P46 has an actual heater core port. The Explorer is the only variant with that blocked off, and this particular intake is designed as a direct replacement part primarily for Mustangs and Crown Vic’s

Okay. I was picturing the Dorman being an outlier, and possibly not matching the Ford alum crossover to just swap o-rings.

Yes. You can't change MAF sensors - not the sensor, not the meter - wthout getting a tune. "Calibrated" MAF/Injectors are a myth - check out some of the MAF sensor articles for more info. You would not gain any HP from the MAF - with a tune you can get a few HP for a better A:F ratio and if you want, more timing via premium fuel. This is where extra power would come from - it's not from the MAF or air intake tube changes. Factory NPI 4.6 heads don't flow enough for either the air intake tube, MAF, throttle body or plenum to be a restriction.

I am getting information all over the place on this site. One says you need a tune the other says you dont. I am currently not interested in performance right now. I just want the car to run. I do not want to buy a non-PI intake only to swap it later once I have money for a tune.

The only non-PI intake available is the Dorman. You don't want that one.

Is it worth it to gasket match the NPI heads to match the PI manifold? Not that I am looking to make the "over-the-fender" job bigger than it needs to be.

When I order the supporting parts - should I just pick a car like an '04 Crown Vic to use? I guess I need the coolant tube, nipple for the water pump, and gaskets. It looks like it's going to take a phone call as I am finding nothing online for the valley tube. Hope I don't have to go second hand.

Also need a couple feet of 5/8" hose and a 90 deg adaptor to connect to the heater hose? Wish there was a cleaner solution for that, don't like extra connections or plastic adaptors.

I like the video where the guy made 4 studs to align the gaskets. Does anyone know the size and pitch of the manifold bolts? Maybe Ace hardware has studs that match.

Thanks,
Al
