Okay i have most of the pieces that i need for the SC install but I am still missing the Air-filter to blower silicone coupler and the metal sleeve insert. I found the part numbers and called stillen but they don't carry it anymore.
My question would be is the silicone couple 3.5in in diameter then the filter is a 3" diameter would i be able to pick something from either homedepot or lowes and get by for now till I get my SC CAI set up made up. Thanks for your help.

 

I have the filter, the coupler, and the metal insert for sale if you're interested.
PM me.

 

I ended up buying a pod filter with a 4" inlet which came with extra spacers to make it smaller. It was a spectre filter if this gives you any clues as to where to start looking.

 

Yes, Home Depot will have a rubber 3.5"-->3" reducer in the plumbing section. This will get you by until you build the CAI.

Autozone, Pepboys etc also carry the reducers you are seeking.

 

Go to NAPA and get a 3 inch heater hose. Hose comes it different sizes trust me thats what I always used and the install is butter. Its the same crap that comes with a SCer kit coated in BLUE.
