Where to get rubber/silicone fittings?

[bmwman91]

I need some silicone fittings, the ones I see commonly used for intercooler piping. Prettymuch, I need a 3" / 80mm ID to 2.75" / 70mm ID reducer. It is to get my MAF to fit the stock intake boot. Who sells these (I'll probably need these custom sized, unless they exist). Any help would be greatly appreciated!

they have reducers like that on ebay all the time, I hear they are pretty good quality also

you should be able to get them at a local parts store, or a diesel performace shop

Autozone has them they are cheap though, and:
