Ships from the maker · 15% restocking fee on non-defective returns · See return policy
This FMIC hose upgrade for the N54 and N55 BMW 335i and 135i replaces the hot-side and cold-side intercooler hoses with single-piece 3 inch ID silicone hoses, 50% larger than OEM.
Why you need it
Single-piece construction gives the charge air one uninterrupted path from the turbos to the intercooler and from the intercooler to the charge pipe, removing connections that cause turbulence. Paired with the matching charge pipe, you get full 3 inch piping from the intercooler cold side to the throttle body.
