2002 WS6 Air Box Dilemma Getting ready to install a transmission cooler and a previous owner installed an SLP FlowPac. Doing research on cooler mounting brought me to the curiosity how beneficial it is to have a bottom feeding intake combined with the WS6 lower air box base. Apparently the two clash in terms of pressurized air flow possibly canceling out any benefits gained.
I was going to cut the bottom portion of the intake for cooler clearance not knowing the effects of the current combo. Now it’s either remove the SLP intake all together, obtain a new lower WS6 base, remove hood baffles, and seal it (would also require new ducting since the original is cut). Or replace the lower with a standard base and keep what’s already there (possibly changing to the Chris1313 which I would still cut for cooler clearance).
Keep in mind my Southwest climate is a factor also and the most important thing is keeping everything cool.
Any thoughts from my fellow seasoned members?

I have a KN air intake setup....thought it would be a good idea to cut the kits lower panel to gain direct air flow from in front of the radiator....I got a great increase in airflow and my SOTP dyno numbers increased greatly.....BUT .....my filter got TREMENDOUSLY dirty and at a faster rate....I ended up putting duct tape over the hole I cut and needed to buy a new filter that got destroyed from all the road dirt....my .02

Or you can take the bottom feeder approach, but as you say, there's increased grime uptake from the roadway and poor IAT's while idling at a stop over hot pavement. But you can always find a non-WS6 lower airbox to hack up for that purpose, while saving your original, and thus not compromise the originality of your car - if that's an issue for you.

IThe baffles behind the scoops render the "Ram Air" ineffective. If you knock those out and use foam sealing strips on the backside of the hood brace opening, you'll see a reduction in IAT's. But it's only original once, and if you do that, you're past the point of no return.

! There’s no originality left even with 36K on the clock it’s about to get my heads/cam L76, Moser 12 bolt, and suspension/brakes from a previous build plus a new RPM level 6 4L60. The previous owners already cut the lower base and installed an SLP bottom feeder. I need room for the transmission cooler and that’s how this came about. I think the best approach at this point is to remove the SLP intake, install a fresh WS6 base and possibly remove the baffles.
the WS6 lower air box has room to put sum type of foam in the openings...highly recommend if you do the RA hood direct air mod....leaves and grass will clog that filter up !
I have thought about this for my own RA hood
