Mazdatrix. If your cooling system has been neglected you may have some serious issues ahead of you. The cooling system in these cars are very vital, and don't take too much abuse, the housings can actually start to deteriorate over time.

That's just for the intake gasket it'self. You also need the 2 O'rings and those are
$3.85 ea. Being that you are paying list price.

Two rubber o-rings, or alternatively two 20mm freeze plugs

Tap those into the coolant holes on your rotor housings where your manifold attaches. It won't interrupt any critical coolant flow for the engine, but it'll prevent leaky problems when removing the manifold. You'll be able to remove and replace the manifold without leaking a drop of coolant, so if you get an aftermarket carb or ported manifold you'll be able to mount it no problem. Also, it'll stop hot coolant from coursing through your manifold, which *might* bring your intake charge down a degree or two.

It's the best way to go, I've got mine done that way.

I have ordered gaskets through Autozone, but any more I make my own. You need to flush the cooling system until it's clean, then replace the coolant. Might as well do the thermostat while you're at it.

Intake is more likely to ice in cold weather. None of the aftemarket intakes I've seen have provisions for coolant ways. My wrap around intake is nearly ice cold at idle, even on 80* days.

Some aftermarket manifolds dont have the passages for coolant in them like the stock manifold does. thats as far as i know...
