Product Details

This is the HKS S Type Oil Cooler Kit No.12, specifically designed for the BNR34 chassis and finished in black. If you're pushing your BNR34 hard, especially on the track or during spirited driving, keeping your engine oil at a stable temperature is crucial for performance and longevity. This kit helps manage that heat by routing oil through a dedicated cooler before it returns to the engine.

HKS has a long history with performance tuning, and this kit reflects that experience. It includes all the necessary components for installation, such as the oil cooler, specialized hoses, and mounting hardware, all designed to integrate with the BNR34's factory setup. The black finish offers a subtle, performance-oriented look under the hood.

Proper oil temperature management can prevent oil breakdown and reduce wear on critical engine components, especially under sustained high loads. This kit is a solid option for owners looking to add a reliable oil cooling solution to their performance BNR34.
