went to classic to pick up a few oil filters, talked to the guy at the parts department he said he'd do 4 filters for 5.50 each! very nice guy. i know SOG has 6 for $40 so its a tad better deal then that.
When I inquired about MAF sensor, part dept quoted me $308 which has msrp of $252.52 and can be bought at $184.72 + S/H (subarugenuineparts.com). BTW, SOG quoted me $208 + tax.
