Will a 70mm Throttle Body Bolt up to a stock EGR Spacer?

[Kdubslugga]

Heres the deal i scored a good deal on a Polished Mac 70mm Throttle Body, and im bolting on a Cobra Intake in like a month or or 2, i dont wanna buy a 50 dollar or so EGR Spacer, when the Cobra Intake will have a built in spacer, so my question is for right now can i bolt the new 70 mm Throttle Body to the stock EGR Spacer without any problems???

The cobra intake is set up for a 65mm if im not mistaken. If it is, you can dremel it out a bit.... but it might work for a 70mm too though.

Cobra is 70mm from the factory

will fit on the cobra, lucky you had that exact one man

Will it fit on a factory EGR Spacer right now? The 70mm TB that is? I wasnt sure if the actual Throttle Body itself is bigger than stock or if its just the opening thats bigger.

No it will not fit on a stock EGR,

Only the stock TB will,
You will have to wait or get a EGR spacer

not even a 65mm will fit. Only stock.

I believe it will fit. Only the bore sizes are different. When you order various sizes from aftermarket, none of them ask what manifold it's going on. The bolt pattern is the same size. Please correct me if I'm wrong.

i bored my stock opening to 70mm using a 2.0" tube sanding bit, just lay your knew 70mm gasket on the throat of your egr, then your intake face and scribe it with a sharp punch or screwdriver. pack lots of rags into your intake throat and duct tape the lower openings, start removing aluminum slowly moving the drill around the opening in complete circles, keep going until that scribe mark dissapears and your done. i ported some of the corners a little to get a little more circle to the opening of the intake. i also bought my 70mm spacer so i only had to do the intake but i could have done the spacer the same way good luck my 70 works great its a mac also.

You're right. It will fit but wouldn't do much good since the egr spacer would be choking it off.

So it's safe to port the stock egr spacer? If so thats good to hear cause it beats buying one.

But another question, Do you need the egr spacer on the cobra intake? I heard that you dont but i'm not sure??
