Product Description

The GReddy x Taarks 12428110 oil block adapter solves a longstanding headache for RB-powered Nissan owners: the difficult, messy process of routine oil filter changes on the RB20, RB25, RB26, and RB30 engines. This bolt-on adapter provides a clean foundation for installing either an oil filter relocation kit or an external oil cooler setup, letting owners move the filter to a more accessible location.

Machined from billet 6061 aluminum and finished in black anodizing, the adapter is laser-engraved with oil flow directions and port information to keep installation straightforward, while durable Viton O-rings ensure a reliable, long-term seal against oil leaks. With ORB/AN10 male fittings and two 1/8 NPT sensor ports, it's built to pair seamlessly with GReddy's Type G filter relocation block or Type I oil cooler block, making it a practical foundation piece for any RB-engine oil system upgrade.
