These are the big daddy side mounts - the perfect solution for those with the B5 RS4, or widebody converted S4, with big power aspirations. These cores each measure 10.03 inches long x 10.24 x wide x 4.72 inches thick. The full kit includes full carbon shrouds, replacement front mesh grilles (RS4 bumper fitment), and all interconnects, clamps, hardware. The basic kit does not include shrouds or grilles, but does still include silicone interconnects, clamps and hardware. This can be installed on a standard narrow body S4, but be prepared for generous cutting of the radiator support and surrounding areas to get it to sit where it should in the regular S4 bumper. When fitting to a S4, some adjustments to lower turbo inlets are also needed (or, we offer options). Pictures shown are as installed on client and friend C’s gorgeous Santorin Blue widebody avant.
