CP-Carrillo Connecting Rod Set, BMW B46

Engineered for strength, built for performance. The CP-Carrillo Connecting Rod Set for BMW’s B46 turbocharged four-cylinder engine is designed for high-performance applications where durability and precision are non-negotiable. Whether you're building a track-dominant race car or a high-powered street machine, Carrillo rods deliver consistent performance under pressure.

Crafted from Carrillo’s proprietary chrome-moly alloy ("Carrilloy"), these rods are forged, not cast, offering superior grain flow and structural integrity. The lightweight design reduces rotating mass, helping the engine rev more freely and respond faster across the powerband. Each rod is CNC-machined, individually balanced, and held to strict tolerance specs that meet the needs of professional motorsports teams.

Compatible with a wide range of BMW models utilizing the B46 engine—including the 1 Series, 2 Series, 3 Series, 4 Series, and X1—these rods come with WMC rod bolts for high tensile strength and optional CARR bolt upgrades for extreme builds.

Note: These rods are not compatible with OEM factory pistons and are intended for use with custom or forged pistons.
