Already own an Active Autowerke CAIS for your ‘95 E36 M3 with the stock 3.0” HFM, but wish you owned an intake system capable of holding a 3.5" HFM? Look no further. Our 3.0” to 3.5” CAIS Bump Up Kit has you covered – at a fraction of the cost of a full replacement system.
Simply remove the old intake pipe, hose with clamps, and air filter. Then install the upgrade components supplied with our Bump Up Kit. You’ll keep your existing intake system with insulated side panels and grill cover. Of course, you’ll also need a 3.5 HFM.
Upgrade kit matched for the Active Autowerke Large HFM.
