[D.W.]

So Killer Bee makes these kits?

Hook'em Horns,
Have you driven in a hard rain with that modified air box? I had mine set up exactly like yours and my filter ended up getting wet. I switched to K.B.'s True CAI. Spring hinged door instead of always open front seems to be a safer way to go.

honestly I would do the mouthpiece mod and keep the stock intake.

The stock intakes have been shown to flow enough air for 500rwhp. And their filtration capabilities are unsurpassed.

Oh yes, at 40mph in a 5+” an hour rain storm on the interstate. There was so much water on the road that the rooster tails from my front wheels ‘Parting the Ocean’ were cab high to the right and left, AND as my Revos never hydroplaned, I could have driven faster but small blind cars wouldn’t get out of the Left Lane (Hate that!)

I’m running a K&N, not paper, with no performance issues and though I didn’t inspect after the drive, I never noticed any signs of water contamination on the filter when cleaned during my oil change.

I really don’t see any concern in this area as it is a ‘Dead Zone’ up front, out of the path of the wheel well action and well above the lower air dam of the front bumper.

From the top…



And from the bottom looking up, with the edge of the inner fender at top running left and right…



I do see a possible inlet of water though, from the front grill, under the headlight, which could easily be addressed.

Besides, how often would one be running WOT during such a downpour anyway? Now traversing 2-3 feet of water in a low water crossing/stream/creek may be a different story. If it would ever start raining again here, I could check this out further with more testing and inspections of the areas.

I agree. It’s like, if the turbo needed a 1’ opening and GM had designed a 3’ opening in the stock design, how is an aftermarket 4’ opening going to help?

AIRAID is the only route to go.... they have the best intake, the best customer service, and the best warranty

Hook'em Horns,
If I remember correctly, you don't have the holes in your right front fender? Maybe that's where I picked up the moisture.

No, mine doesn't. I read where GM realized an issue with those holes and moisture, as they started capping/covering them up in later LB7s and early LLYs. Mine is a late '05 production truck with no holes stamped, just sheet metal.

Mine had the holes, but had a silver sticky pad over them.
