The aFe BladeRunner GT Series radiator is a direct-fit cooling upgrade for the 2012-2018 Jeep Wrangler JK with the 3.6L V6. Its 1-3/4 in. bar-and-plate aluminum core is about 25% more efficient than the factory tube-and-fin design and offers roughly 25% more coolant capacity to maintain cooler temperatures. The 100% TIG-welded aircraft-grade aluminum build uses 1/8 in. end tanks and a 1-1/2 in. billet aluminum inlet/outlet. The kit ships with upper and lower 5-ply silicone hoses in black, stainless T-bolt clamps and a heavy-duty brass drain valve, and bolts to the factory mounting locations.
