I got my gasket and parts from Spins4 and realized while the stock o2 housing gasket is very thick it doesn't have the divider along the wall for the o2 housing like many aftermarket gaskets I see. I'm assuming since it comes from the factory that way it's fine but with an aftermarket o2 housing is there any significance in that gasket running along the wall there?

Thanks!

Use the factory gasket. The aftermarket exhaust gaskets tend to leak after awhile. I'd reuse my original factory gasket before I'd install one of those aftermarket ones.

Obviously, if the factory gasket doesn't have a division then it is not required. Just toss the aftermarket gaskets in the waste receptacle under your workbench. JMO
