GT-40 install advise

Hi everyone,

Was hoping for some help. When I purchased my '89 GT there was an intake in the trunk, in a box. I just put it aside. Last night I went to look at it and I think it is an Explorer set up. Someone had told me that you need to drill and tap a port by the #5 cylinder for it to work. Looks like that is already there. Looks factory too. If I put this on my car will it be a noticeable/enjoyable upgrade?

I am an average backyard mechanic so would the install be simple? I just chased a PIP issue for weeks and something tells me to leave well enough alone now that she is running perfectly.........that's just not how we are wired!

Does anyone have a checklist of things I need to do to install. Heard the vacuum connections are a challenge.

Anyone have an installation guide?

On the car I now have:
BBK 70mm throttle body
BBK cold air fender well intake
BBK shorty headers
MSD Streetfighter box, coil and distributor with wires
PA Performance 95 amp alternator
American Muscle BAMA chip with the 3 modes.

Thanks so much.

If you google "explorer intake install" you'll get a million how-to hits.

Well look at pics online of the explorer intake/gt40 intake and look at yours. They are impossible to confuse. If the lower is a GT40 style and it has the bung already tapped in #5 then its either an OEM Cobra lower or somoene tapped it already. Either way you can just relocate that sensor to the inlet tube if you don't want to drill/tap.

As far as the intake swap itself, very straightforward, as long as you have hand tools and a torque wrench you are good. Google "explorer intake swap" and you'll get multiple install threads/guides.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
