New gasket for BIM and BBTB?

[shianux]

Hi, I drive a 2002 Elantra XD.


I'd just like to ask, if I take out the intake manifold to port match it to a new 58mm BBTB, do I have to replace the intake manifold gasket and throttle body gasket?

And if I do have to replace the gaskets, do I have to change the sizes as well? I'm pretty sure I can order OEM Hyundai intake manifold gasket, but is it possible to get a 58mm throttle body gasket from Hyundai?

I didn't think it would be possible cos the stock is 54m.... so how do I get a 58mm one?

Thanks!

I think the OEM gaskets are already about 58mm (not positive). If they are then you would only have to replace them if you tear them. If they are smaller than you could always make your own.

There should be no need to buy a new IM gasket unless you damage it when you remove the IM. Not sure of TB gasket, pretty sure it was large enough to not warrant an exchange.
