Product details
OVERVIEW
On a hot track day the E9x M3's power steering fluid heat-soaks, and steering feel goes vague just when you need it. The do88 OC-120 replaces the small factory power steering cooler with one holding twice the fluid and more than three times the core volume.
It's built for track, endurance and spirited street use, and drops in on the factory lines and brackets with no modifications, on both DCT and manual cars.
