Designed for the B46 turbocharged four-cylinder, this is a critical upgrade where forced induction places extreme stress on the head gasket, main caps and connecting rods. Standard torque-to-yield fasteners stretch permanently and lose clamping load over time — ARP hardware restores and increases that clamping force, helping prevent head gasket failure, cap walk and fastener fatigue.Available options for this engine:ARP2000 — a 220,000 psi alloy steel, the proven choice for performance builds and quality rebuildsSupplied with ARP Ultra-Torque fastener assembly lubricant. For best results ARP recommends installing to a measured bolt stretch where possible, ensuring accurate and repeatable preload.CompatibilityBMW B46 Models BMW G20 330i BMW F30 LCI BMW B48 Models BMW G20 330i BMW G29 Z4 30i BMW F40 / G42 Why Choose ARP (Automotive Racing Products)?
