Product Description

The Wilwood 221-17413 is a rear stainless steel braided brake flexline kit built for the E46-chassis BMW M3 and 330Ci, designed as a direct replacement for the factory rubber rear brake hoses on these coupes.

The braided stainless construction with a Teflon-lined interior resists the expansion that rubber hoses develop over time and under hard braking, delivering a firmer, more consistent brake pedal. Being DOT-approved, this kit is legal for street and highway use, not just track applications.

This kit covers the rear hoses only - M3 and 330Ci owners looking to replace both front and rear lines will need a separate front flexline kit for this platform. Since one part number covers both the M3 and 330Ci for this generation, confirming that both trims genuinely share the same rear hose routing is worth a quick check if precision matters for your listing.
