Got rid of the stupid air box, idk if just a coincidence but the truck is running better, misfire is pretty much gone, still pops up on live data here and there. Now I'm wondering if this thing was pushing down on some wires causing high resistance.

 

How are you preventing the engine oil from sucking into the throttle body?

 

Same way with the stock resonator.

If it gets bad enough I'll just add an oil catch can, have an extra one laying around somewhere.

 

You do NOT need any catch can (useless POS if there ever was one). We have sold 1000s of intakes, our four testers, including my old 07, had zero oil in the intake. Those were painted silver to be able to see residue upon inspection.

Here is one after 50K miles. You decide if that is a concern, I know it is not.

 

The original OEM stock resonator collects any blow-by!
