Is the 993 and 993tt outer air box cover the same? If so what years match the TT.

I need to find another stock outer cover to do some testing with.

96C4S

IIRC there different turbo is a sealed unit and wouldnt the filter be before the turbo.

Same lids Kevin. If you find a NA one, you just have to pull out the plastic internal inlet part so you can replace with a turbo trumpet. I have done this a number of times for guys that remove their rear decklids and do to a raised wing. The inner part of the box is the same for 95, but 96+ they went to the twist on MAF into the airbox. The turbo just used the sping clip to the MAF like the '95 inner box (except the turbo only uses one spring clip).
