The shortram pipe is an Arospeed short ram i got in a group buy and the CAI extension is the 92-95 Civic short ram that I got from AutoZone. Id suggest you get the Integra GSR CAI off of eBay though, do a search and you will find enough info on how to make a CAI for under $75

you better off just getting a 4 or 4.5 incha air filter...or buy a 3 inch MAS adapter. if you would have clearly read the other post under customizing 7G you would have noticed that the regular MAS Adapter is big. and if 3 inch is a normal size you would know big means bigger than 3 inches. i have both a 3 and a 4.5 inch filter, the 4.5 for a regular ram intake becuase of the mas adapter... and i got a 3inch filter for my cold air intake for those warm summer nights...oh how i miss them right now... but anyway if you want to stick with what u got which is a 4.5 inch MAS Adapter and a 3 inch filter. your most likely gonna have to go with a cold air intake. just go to home depot and get a 4-3 reducer and get an intake pipe like previously posted..either a civic since most people are familiar with that or an intagra pipe ...i would have no clue on that since i havent tried that out. put the 4-3 reducer on the MAS Adapter, pipe to the 3 in side of the reducer, and filter on the end of the pipe..isnt hard at all. good luck.. get back to us with what you do...hope this was helpful.

i was also thinking of taking sillicone glue and glueing the filter to the adapter would that work

your still gonna need a pipe. theres no where to connect the filter to. and i dont think connecting rubber to rubber is gonna hold up that well.

don't even bother doing the short ram pipe that goes from the back
of the air sensor to the throttle body, it is smaller than the stock
size and reduces the air volume and flow. As for the front of the
air sensor going into a cold air intake, nice.
