GReddy 15-21 Subaru WRX / STI Hi-Capacity Oil Cooler Kit

This is the GReddy Hi-Capacity Oil Cooler Kit, specifically designed for the 2015-2021 Subaru WRX and STI models. If you push your turbocharged Subaru hard, especially on the track or during spirited driving, keeping your engine oil temperatures in check is crucial for longevity and consistent performance. This kit helps manage those high oil temperatures by adding a larger, more efficient oil cooler to your engine's lubrication system.

GReddy has engineered this kit with a focus on increased oil capacity and improved heat dissipation. The larger core size allows for more oil to circulate through the cooling fins, which in turn helps to lower the overall oil temperature more effectively than the stock setup. This is particularly important for high-performance engines like the EJ25, which can generate significant heat under demanding conditions. The kit includes all the necessary components for installation, such as specialized adapter blocks, high-quality hoses, and mounting hardware, ensuring a clean and integrated setup. The adapter block typically replaces the factory oil filter housing, providing convenient ports for the oil cooler lines.

Properly managing oil temperature can prevent oil breakdown, reduce wear on critical engine components, and help maintain consistent oil pressure. This GReddy kit is a solid option for WRX and STI owners looking to add a robust cooling solution to their performance build. It’s a worthwhile addition for anyone serious about protecting their engine during high-stress driving scenarios.
