Okay I'm gonna be pulling my intake manifold off to swap it for one designed for my car. (1993 and below uses butterfly valves, 1994 does not)

Things to replace:
-manifold gasket
-plenum gasket
-throttle body gasket
-pcv valve
-all vacuum lines under manifold (anyone know the size hoses to get?)
-wouldn't kill me to change knock sensor... 140k miles, should i change it?

Anything else I should look into changing while the manifold is off?

Dry rotted water/heater lines...Also wouldnt be a bad idea to replace the EGR valve and clean the pipes.

butterfly valves are a waste, that's why they weren't used on later model KA's

EGR is getting removed, that turd stopped working a while ago. Yeah there's a ton of water lines behind there.... ugh makes me want to just pay someone to do it

I know they're a waste, that's why im putting the manifold on that doesn't have them lol
