i bought from that same ebayer last week. he sells a kit with both the intake and tb spacer for like 60$ free shipping. it came with all the gaskets, screws, etc. and is really good quality. i bought on a monday or tuesday i dont remember, and it arrived that friday. i don't know the guy but if he sold something else i needed i would definately put the business his way again. i dont have time now but in a couple hours i'll post some pics of everything that came in the package.
the plan for me is i'm p&p'in a stock plenum and will swap in the 2 spacers and plenum at the same time once i'm done with the grunt work on it.
all together it's costing me like 80$ since i had a pile of bits for the dremel already. sure it wont be as nice as a full accufab kit, but with the 300 saved i'll probably pick up a strut tower brace and densecharger.
