ok im lost on like everyones posts so here it is...
a CAI is a great buy! a short ram is a horrible buy! the CAI's for these cars make nice power and as long as you dont spend money on a name drop intake they are affordable too. a short ram will destroy power! the engine bay is way to hot. even with me having a CAI that does not have a heat shield i lose 15HP and TQ when the ambient temps go up about 10-15 degrees. needless to say from winter to summer i lose an ass load of power. now think about how much more you'll lose with the filter sitting on top of a hot engine bay. these cars are fully controlled by the MAF sensor and keeping that thing as cold as possible is a must. also if you start sucking in hot air you will be putting the engine more at risk for knocking. if you get a tune with i short ram your tuning will have to keep timing down to prevent knock, now you've lost even more power. also these cars have very good fender plastic protection wheel things (brain fart). ive drivin through massive puddles and the filter stays dry all the time. do not be scared about water and a CAI.
to sum that up get a CAI with a shield.
as for a TBE, great buy! as long as you use it with a stage tune 2.
as said on the BOV, dont do it! as for an aftermarket BPV, dont do it!! your stock metal BPV can handle plenty of boost! its not plastic like the crappy WRX ones.
