Right now? The CP-E or Cobb kits. I haven't actually seen someone with the F2 kit, just people "talking" about it..and some guy test fitting it who doesn't know anything about intercoolers or the questions to ask. DCR is probably working on a kit too, it'll probably be top notch, but you can be guarenteed it ain't gonna cost no 750...it'll probably be 1-1.2k like all the other decent kits.
I never liked the corksport location of the intake on top of the engine...the whole point of the FMIC was getting stuff OFF the engine. Heat rises people!
But the corksport is the best overall bang for the buck, so everyone will keep buying it

. Just like everyone buys the fuel pump internals, then watches them fail, then buys them again, then watches another set fail...eventually everyone will just end up buying the full replacement pumps, but it'll take another year of failures before everyone finally realizes you can't calculate those types of tolerances with a caliper...
That's the budget way...it always ends up costing more in the end, but you can't ever explain that to someone, you just have to watch a few hundred people do it repeatedly on the forums.
Here's a tip...if you are buying a product with a notation such as "Version 2, or V2, or V3 etc" maybe you should look for a different product...lol.
