Returns/Shipping

A pair of performance auxiliary radiators for the B58 Gen 2 engine. The B58 cooling system has one large central radiator and two smaller radiators in front of the wheels. The standard auxiliary radiators have thin cores and plastic tanks, which do not suit tuned cars on the street, track or strip. The do88 radiators are drop-in replacements for both sides. They are sold as a pair because upgrading only one side is less effective.

Features

Larger core volume than the original equipment
Dual-row core 40 mm thick
Full aluminium construction with durable TIG-welded end tanks
Increased fluid capacity
CNC machined mounting brackets and OE-style quick connect inlet and outlet connections
The OE rock guard can be refitted to protect the radiators
