You have to remove it as there are air dams at the end of each intake runner.

You need to remove the intake from the engine bay to port it. The intake manifold isn't that difficult to remove. You can actually remove the manifold, fuel rail, and throttle body as an assembly if you want to.

Here's a tutorial:

How-To: Remove 1.4L Intake Manifold Overview: This tutorial will show you how to remove the intake manifold. Because the PCV check valve inside the intake manifold is prone to failure, this will be something you'll have to do at some time in your Cruze ownership if it's out of warranty. You...

How much power is to be gained from this? Does this take away low end response for high end HP?

Yes, definitely a little low end loss I think, better high end though. Intake manifold spacer brings some low and a lot more mid. Probably 10hp gain, you can feel it though.

Won't the engine computers adjust the air/fuel ratio to certain parameters anyway ? IOW, when you add more airflow, the computer adjust fuel and vice/versa so you really don't get more power.

I think you answered your own question in the last sentence. You get more airflow so the computer sends more fuel. More fuel and air equals more power.

I can verify you get more power from a ported intake manifold, specially around mid rpm range. I cant wait to see what happens once i slap a tune on it. 🖖

Removal is simple enough just take your time, the hardest hose to remove is a 1/4" vaccuum line that is connected directly on the bottom of the manifold itself but could be done with some skinny hands lol

I take that off after I unbolt the manifold. It’s plenty long enough.

really? on my 2011 I only have about 2-4 inches of slack from/to the front of the car

No. I didn't say it sends more fuel or more air. I said it adjusts to what it is getting. You will wind up with the same output. Tuned is different. Stock tune can't be fooled simply by adding more air or more fuel.

"when you add more airflow, the computer adjust fuel and vice/versa so you really don't get more power."

????????????

You are saying with more air flow the computer will adjust for more fuel and less airflow less fuel. More air and fuel equals more power. Help me understand where you're coming from.

@Thebigzeus and @2014 Encore this thread is not about the merits of a ported intake manifold. The OP asked if there was space to port the manifold without removing it. Which the answer to that question is no. Since this thread has gotten off topic and I can see it is going downhill, this thread is now closed.
