Default Blackwing Intake Idea.

Just below where the intake filter sits I was thinking of cutting out a section of that panel about 12x8 inches,then putting some type of a screen over the opening.I would think that now you would be drawing cooler air up from the bottom instead of from the engine compartment.If the opening was high enough up on that panel I dont think there would be a problem with water entering. Feedback please

This has been discussed a lot...I asked the same question when I had a BLACKWING, thinking of drilling holes instead of screen to maintain the structural rigidity. The shroud does tend to sag when it's cut.
Some people stated that allowing the cooler air w/o an enclosure around the BLACKWING (ala "ice box cover") would "confuse" the computer.

Take a look at my CAI mod (second procedure down). I have reams of data (from a Car Chip data logger) that shows this mod makes a huge difference when it comes to slow/stop & go driving intake air temps. This means that your ECU will NOT retard timing because of intake air temps above 100 degrees.

That is VERY cool. Good idea! Any issues with radiator/engine temps since you are snatching some of the air for the air intake?

Not sure of what I want to do right now,I think Donaldson makes a shroud kit that goes over the Blackwing to isolate the warm air from the engine compartment.I will look into that also.

None whatsoever! The only downside is that you need to clean the air filter more frequently, but that's a small tradeoff in my book.

The disadvantage of having a completely enclosed housing over the filter is that the engine bay continues to bake (unless holes are cut into the fog light panels), especially if it contains headers. I didn't want either the Z06 screens or large holes showing up front, so I selected the lower radiator cover to bring fresh outside air in.
I know from experience that hot engine bays tend to shorten the life of hoses, belts, batteries, and most importantly, EBCM/electronic units. The CAI mod not only keeps both the intake air and the engine back cool, but also keeps flow restriction to a minimum.

Defender,

The mod works with a Blackwing, as well.

I thought the same but it was pointed out to me that you are still getting the hot air that is circulated from under the hood. Also you get more dust under the hood from outside.
So I went with the "Icebox" install. It works great you are getting the air directly from under the car into the enclosed air filter.
Great ivestment for the Blackwing.

If you have a MN6 and there is just 1 big hole the size of the filter element you will get intermittent 101 codes from turbulance at the MAF, on deceleration, in fourth, at about 1700 RPM. I know mine did. Might want to consider the cover from Donaldson.

The only C5s that can have lean codes due to turbulence past the MAF are 02-04 Z06s. Their MAFs do NOT have a laminar-flow screen, so the increased flow of air results in the code generation.

If your C5 throws codes after installing an aftermarket intake, check the MAF; the previous owner may have removed the screen.

As far as dust - yes, there will be a bit more, but remember, there isn't just a "big hole"; the hole is covered by a fine-mesh 316 stainless steel cover.

You'll notice a difference with it done that way!

I did it to my K&N FIPK when I had it, worked out pretty good!

Thanks,Matt

Have not had any problems with my mn6. I did a modification similar to Dave 68 but with out the wall pocket when I installed the blackwing. That was eight years and 100,000+ miles ago. The blackwing has been cleaned twice even though the indicator on the filter hadley moved.
