Default Hydroboost intake plug part number?
Does anybody know the part number for the plug that goes in the back of the intake on a hydroboost equipped truck (LQ4)? Mine has the nipple for the vacuum brake hose, and I want to delete it. My search turned up nothing. Thanks.

...or try looking at CompNine.com. They have all sorts of part numbers for things I can't find anywhere else. I usually take those to the dealer and buy what I need. Of course a quick spin didn't turn up what you are talking about, but I'm at work.

I went to Westfall GMC, but the problem is I don't know exactly what it's called. the guy there looked alot, and I did find the nipple for the power brake hose to hook to,it was only like $5, but can't find the plug.

Hahahahaha!!!! Amazing, isn't it? I would have to see if one of my friends has a hydroboost on their truck and see if the part number is on the plug.

The LS4 guys swaping to the LS1 intake use a 1 31/32" freeze plug:

Very tight fit!

Hey Rick, it's in the back of the intake. What are you doing for brakes? Power or manual? Vacuum or hydroboost? I'm thinking that vans had vacuum, so you probably have the hose.

Truck intakes are a little different, the plug just pushes in. Thanks anyway though.

It's off of I-29 by the airport at the old Farmland building. You were probably thinking the dragstrip, huh? Couldn't be that close. You should consider going it's usually a good show.

Hey, this is joe from NTA (North Town Alignment) I have two of these plugs at the shop if you want one. The last two swaps came from hydro boost trucks.
