Has anyone changed their stock 997.1 one filter airbox to the one in 3.8l or 4.0l motor with 2 boxy filters (or aftermarket)?

Might there be any gains or looses with this mod?
I am guessing you need to cut a hole under the left air intake on the hood/engine lid.

Any ideas?

 

you know this was posted in the 996.9 section ?

 

Oh sorry, just seen it
Dont know how it happened, guess my fat fingers do not go well with ipad..

If mods can move it to GT section i'll greatly appreciate..

Sorry..
