RB Oil Filter Block – Billet Oil Cooler & Relocation Adapter - Demon Pro Parts

The Demon Pro Parts RB Oil Filter Block is a high-quality direct replacement for the factory Nissan RB oil filter block, designed to safely support oil filter relocation kits and external oil coolers without the common leak issues associated with screw-on adapter plates.

CNC machined from 6061-T6 billet aluminium and anodised for corrosion resistance, this oil block provides a reliable, long-term solution for performance and track-driven RB engines. It features additional sensor provisions, making it ideal for builds requiring oil pressure and temperature monitoring.

Unlike gasket-based designs, this block uses standard Viton O-rings, ensuring a superior seal and easy servicing with readily available replacement parts.
