im wanting to install a FAST lsxr 102mm intake manifold and throttle body on my ls1, where can i find bellows to fit an opening that large and what air lid and mass air flow sensor would be best suited for that much air flow??? i already have the whole SLP intake setup on their currently (mass airflow sensor, cold air intake, bellows, intake manifold, etc...)

I'm running a FAST 102 intake, 102 NW TB, 85mm maf, and a SLP lid. I wish that I had went the 104 lid, 100mm maf set up but if you choose to go the 85 route I used a piece of fernco from home depot. It was like 8 bucks.

If you dont have H/C or any other engine internals modded i would stick with the stock/85 MAF because the maf being a restriction on a Un-modded engine wont be a problem. FTP lid 98 or 104, and just google silicone couplers and you will get a lot of websites that sell reducers/couplers.
