quick question
 

Hello i have a 2000 montero sport xls,gonna change the spark plugs but i have been reading that i need the plenum intake gasket also,i looked online for it and lists lower and upper gaskets for that could anyone tell me which i need or both...thanks

As long as you don't remove the intake manifold you only need the upper. It will look like the picture I posted below.

ok thank you

Technically speaking, you need to replace both. However, I've re-used mine many times without any problems. If your plenum is tightened down to gorilla torque specs, you need new gasket because old one will be crushed too much.

ok will order both then...thanks HunterD
