Wondering if there are any aluminum or otherwise metal intake manifolds that will fit the 4B12 (2.4L) engine? I wanted to take a look at what I'd need to port the intake, and noticed it looks to be entirely plastic. Is there a comparable IM from either another Mitsubishi vehicle or maybe an aftermarket IM I can use that fits and has the appropriate ports for the sensors?

 

I believe the Evo X intake manifold bolts on.

 

Aren't they different blocks? That's the 4B11, do you know if the manifold has different clearances? or any modifications I'll have to make in order for that IM to work?

 

Same head though, isn't it?

I actually don't know much about the NA lancers.

 

Just left the dealership and they tell me it's a different head and fitment. The gaskets don't even line up.

Still looking for an aluminum substitute for the 4B12 intake!

 

Dealers are not a source of information.

Simple internet search shows multiple NA lancers with Evo X intake manifolds. I would check out the forums

 

Just an update, turns out you're right, I was able to find a couple sources online where the manifold bolted right now, but will need new fuel rails and throttle body, as well as an EGR delete. Currently looking into how I can get this done now

 

Hope you find out some more info, as I am trying to build a 4b12 as well just for a little more power but not much information out there
