The other day, I was under our LSE changing the oil and I noticed where the stock air box draws it's air. Behind the headlight, there is a hole (maybe 3" in diameter) in the inner fender that has a duct for the air box pointing toward it. This got me to thinking...what if...
What if you cut the bottom of air box out to open it up and install a K&N panel filter? Why would this not flow as well as a K&N cone on the end of the MAF? Seems like the surface area of the panel filter would be close to the same as that of the cone. A side benefit is a built-in heat shield. The bottom half of the box could serve as a heat shield to protect the air tract from engine heat.
I have done this on two previous cars (a 99 Grand Prix GT and a 96 Sonoma). Both seemed to perform better all around...particularly at speed. There was some what of an increase in noise (the infamous bog) but nothing like a cone filter would add.
Anyone ever tried this with an LS? Or...can someone disprove why it wouldn't work as well as a cone filter?
TIA,
