this is my area of expertise...
while I still have weak 2.73's in my old vert and have no intention of swapping cams, heads, intakes or converting to mass air, I can proudly and confidently assist you with finding the best car cover for your application.
First of all, you will be hard pressed to find a better deal (and better service) from big sky car cover

That said, question is, how much 'bulk' can you put up with, how much protection do you really want, and how much do you want to spend?
Best covers are:
Evolution 4 (THICK AND BULKY)
NOAH (Less Bulk, more waterproof, more $$)
Block it 200 (Less of everything, less $$ too)
I have owned and still do own all three for a number of my rides.
Let me know, I can help.
