HKS Air Filter Hoses

So a friend of mine gave me a used HKS air filter system he no longer had a need for and so far I have installed it in my truck by clamping the new filter hose over the old one because unfortunately they are different sizes. Does anyone have a remedy for this, maybe know if it's even possible to find a hose that goes from the stock 74 mm (2.91 in) up to the new filters 83 mm (3.27 in) size. Any help or suggestions are as always much appreciated.

Thanks

You need a reducer. Probably available at your local auto-parts store, but if not, then online.

Thanks that's just what I looking for!
