Designed for BMW’s M40-series four-cylinder engines, this is a critical upgrade making it an essential upgrade for any high-performance rebuild or boosted conversion. 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.\u003c\/p\u003e\u003cp\u003eAvailable options for this engine:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eARP2000 — a 220,000 psi alloy steel, the proven choice for performance builds and quality rebuilds\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eSupplied with ARP Ultra-Torque fastener assembly lubricant and torqued in stages to ARP’s specification.
