My oer/ SK intake plan is going to be perfect. Basically I’m looking for a clean way to do iac and pcv. I will have a plate machined to cap this faux balance bar. Then tap each runner for 1/4 or 3/8. I love the oer/ Sk linkage.  The IAC and PCV will be done on the bottom out of sight.  

This is what the Sk/ oer intake look like under that cap.  Casting is a little rough for my personal tastes.  

I will use a Bosch 0280140551 IAC.

Looks good. I have looked at the FET intake for the same reason. I have thought I might get the jenvey 50’s with intake and see what that looks like. 

 
On a side note I recently added a stock intake heat shield to my customer car with the harada intake. It fit really well and makes a huge difference on intake heat. The under carb/throttle body heat shields really fall short of the area with the most heat. Since the car was already together I just made a crude bracket to hold it from the top but it still looks ok. For my mangoletsi intake since it is webbed it should be able to be done cleaner. I have also thought with the Jenvey since it is angled up a bit it would fit even easier. You could also well bolt bosses to the bottom.

It also does not interfere with the Oer under throttle heat shield and gives a double layer for a bit. Might think about this while messing with the underside. I have a couple very nice condition heat shield I was thinking I would send out for a heat reflective coating.

You should get the top aluminum plate engraved with the old SK sport kit graphic. Today with the laser engravers prob wouldn’t cost much. 

 

 

I will make the cap nice looking.  Somesort of SK logo.  I will keep it simple, but add some flare.  

 

The casting is pretty rough, first step is to knock that down.  My local engine shop has a huge vibratory polisher.  I might try that first.
