Which Gaskets to replace?
 

I'm about to remove the TB and upper intake to get at the secondary injectors. I'm going to have them cleaned and balanced. Which gaskets will I need to replace in this process?

Thanks in advance.

I would leave the TB on the upper intake so you dont have to replace that gasket. If youre going to remove the secondaries, you might as well get the primaries cleaned too, theyre right there. Youll need the upper to lower intake gasket from Mazda, part number 13-111D-N318. You should also get new upper and lower grommets for the injectors, and new injector o-rings. The dealers will know all those parts #'s, they vary by injector.

Anything else?

Thanks for the info! I didn't realize I could leave the TB attached.

I'm going to leave the primaries in. I could get new higher flow secondaries for the cost of cleaning all 4.

Are you positive I need the upper to lower gasket? I've never done this before so any advice you can offer would be appreicated.

Yes, you should replace that gasket. That is the only one you should need.

There is no gasket toreplace betweon the upper and the tb.
