As some of you may know, I own a 1996 K1500 with a Vortec 350.
The truck originally came with a K&N CIA which I eventually removed in favor of a factory high capacity OEM air intake. I felt the K&N was sucking underhood hot air.
I didn't feel any loss of power making the switch.
However, I was poking around the engine bay of my truck the other day, when I noticed a plastic tube in front of the battery.
Low and behold, this tube feeds air from the front of the radiator support to the inside of the fender. Of course, we all know where the engine picks up cold air from.
I haven't removed the tube yet to see if it might be an air flow hindrance. I doubt that it is because, like I said, I felt no power loss going back to an OEM high capacity air intake.
I have never heard anyone mention this tube and it got me to wondering about the actual benefit of an open element CIA like the K&N.
I will get a good look at it eventually and come to my own conclusion about how it may or may not impede air flow.
I wasn't sure if any of you knew about this tube, but whether you do or don't, you all may want to take a gander at it anyway........if it's still there. There might be a hole where it was.
I would bet the earlier TBI trucks have it also.
I guess this post is more of an FYI than anything.
Comments are welcome.
