replace snorkel with cone filter

[Most_Wanted]

There's a vid on youtube of someone splitting the airbox in half at the seams with a flathead. Claims it takes only 10 min. I'm thinking i'd run tubing into the snorkel area and fabricating a plate to seal it from the engine compartment. I already have the 997 tb/plenum so after this i'll be mostly satisfied with the intake side of things.

The 986 maf housing is detachable from the airbox? Or does it have to be sawed off?

Before the Demolition begins, I suggest you investigate the void between the inner and outer wing. This is where the original snorkel is fitted. The space is an irregular trapezoid.
I used it for the filter media(Unifilter).
Then you need to source the rest of the ducts,elbow,adapters and connectors to reach the MAF
You will need to fabricate a plate to fit over the hole in the inner wing .The plate needs an integral flange to connect to the largest elbow that will fit.
There are details in other Threads if you Search.
If you fail to get a perfect seal on the entire system and good filtration you'll get MAF contamination codes/faults.
