like i've said before, you need a 70mm adapter, silicon connector (70mm), and the filter. the adapter comes with the filter, so just order the adapter. it should come out to like $75ish. you'll get the filter, gasket, adapter, and screws. you won't have a place for the iat sensor unless you drill the adapter... i didn't want to do that, so the iat sensor is RIGHT NEXT TO the filter. you'll get some rubbing against the coolant bottle, so put the metal connector on the filter against it... you'll know what i'm talkin about when you get it. good luck.
forgot to mention, i had it on the maf for a couple of months, i now have it on the end of the AEM cold air.
