Before I get smashed and told to google I did... As well as going through all 7 pages on the Explorer intake thread.

The intakes I have here have casting #'s of

Upper RF-F77E-9425-AB

Lower RF-F87E-9K461-BA Then at an angle it has the #'s 3297

I called the local Ford dealer and was told they can not pull those #'s that the intake should be a 9424 not a 9425 ????

I just want to make sure these are correct before putting any work into them..

The lower intake "F87E-9K461-BA" is an Explorer lower. It's the earlier version that features the boss for the ACT sensor.

This intake also appeared in the 1997-2003 Cobra Intake Ford Racing kit, featuring drilled out cooling hose ports and a drilled and tapped ACT port.

So if the lower ACT boss is drilled and tapped, it's probably a Ford Racing lower. If it's not, it's an explorer lower.

The F87E-9K461-BB lower is the later ford Explorer intake that doesn't have an ACT boss. The -BA intake is the one to have.



The Upper is an Early Ford explorer upper


Sounds to me like you have a 96-97 Explorer Intake setup with ACT Boss (not drilled and tapped) and provisions for EGR in the upper and lower intake. This is the preferred Explorer intake to have.

Thanks for the quick reply.

Now on the top of the lower intake at the front one tubes has a #5, just to the right and slightly above there is a hold with threads, that looks newer than any other. I mean newer as in it's shiny while the other drilled holes are not.

The upper does have 2 small metal lines coming off of each side under neath and 2 pipes that still have rubber hoses on them from one side. Then two other pipes with hoses, looks like for coolant???

Wish I did not leave my phone at home today or I would just snap a pic and post it lol.

Sounds like by going off the casting #'s they are the ones I want to use. I don't see the point in deleting my EGR, so I will be able to still use it on these with no other modifications?

Last question.

Should I try and port these bigger with me still running stock heads, or just leave as is and bolt them up..

Also from what I read the phenolic spacer is not that big of a deal???

On the lower, the ACT is drilled into Runner #5, so it sounds like someone did that. At the rear of the lower intake, should be another boss over each coolant port. These are for the EGR spacer coolant lines. Both are usually tapped but the 5.0HP uses the passenger side one, and the standard 5.0 uses driver's side. If you run an EGR spacer and use coolant lines, you'll need to tap the passenger side one with 3/8" NPT

The only coolant lines on the upper should be the EGR spacer. I think the explorer one is angled anyway, so you'll need a Mustang EGR spacer.

As for the vacuum lines..im unsure really. I personally run a Cobra upper so i never installed an explorer setup

I actually have one of these intakes. I bought it for the lower so i could send out to Tmoss for porting to use with GT-40P heads. I've been debating selling the upper. With bone stock heads, unsure if its worth it. However, if you ever plan on upgrading in the future, i'd definitely do it now as the intake is off the car.

Those are all vacuum lines on the upper intake. Some will get capped off.


On the lower, the coolant port is the newish tapped hole at top right side. It connects to the EGR spacer and the other side goes to the heater pipe. It's just like the stock intake

I found this thread. The difference from what I have comparing to the one on his right, is that mine has 3 hoses on the right where his only has one. Also the one he has is going to a fitting near the back, then another hose hooks to the other side of the fitting. Mine only has a one sided fitting. I guess just different years???
I'm just trying to get a visual grasp on how this works, that's all. Thanks for the patience.

No Prob

Looking at this pic, you probably want to set up your intake like the one on the left, even though your's is on the right. As you can see, most lines are capped.



What some guys do is actually yank out the tubes, drill and tap an NPT plug and cap that hole. It's what I would do. On the intake on the left, you can actually see the guy removed the lower left tube, and tapped the hole to use the Mustang intake "pipe" in it which the vacuum lines all connevt to. Other than this "Pipe", the PVC tubing and a single port in front for the Charcoal Canister, everything else gets capped.

OR, you can run the large line on bottom left to the Vacuum tree, and then out a TEE on the smaller line for the fuel pressure and EGR valve. Then you just need to use one front port for the charcoal canister and cap the rest.

So if you are good with a drill and NPT tap, might be something to consider.

Mine has all the hook ups like the one on the left, but also has the opening in the middle that you have circled on the right.

Either way I have a guy that has done quite a few of these gonna stop by our shop tomorrow and look at the set up. I have never personally done this work. I'm gonna let him do the install as well. To me it's worth it to pay a small amount to have someone do it right. I don't want to try this and screw something up that will cost me more in the long run. I really just wanted to understand this swap more before letting it get done.
