The STM Billet Aluminum Slim Radiator for Evo 7/8/9 models combines lightweight construction with efficient cooling performance. With its streamlined billet aluminum top and slim profile, it offers a sleek upgrade for your vehicle.
Featuring a cleverly positioned upper radiator hose fitting on the right side of the engine bay, this radiator provides ample clearance for larger exhaust manifolds. It comes with interchangeable fittings, accommodating both factory-style radiator hoses and -16AN lines for added versatility.
Unlike traditional radiators, this model doesn't include a bung for a radiator cap. Instead, it pairs seamlessly with the STM Water Neck for Radiator Cap Relocation, relocating the cap to the highest point in the cooling system for optimal performance.
Designed to integrate flawlessly with factory mounting points, this radiator ensures a secure fit without compromising bracket bushings. Although it lacks a drain port, it remains lightweight at 11.85 pounds, fittings included, making it an ideal choice for performance-oriented Evo owners seeking superior cooling efficiency.
Vehicle Fitment:
2001-2006 Mitsubishi Evolution VII VIII IX
• Does not fit with factory air box
• Requires Evo 4/5/6 upper hose or -16AN fittings and line
• Must remove rubber bushings in A/C condenser
• Requires radiator cap relocation
Includes:
• Radiator
• Fittings for OEM Hoses
• Fittings for -16AN Line
• Extra Fittings (note, two small fittings will not be needed for Evo)
• Mounting Hardware for A/C Condenser:
(2) M6x20 Stainless Bolts (MS2550020A20000)
(2) M6 Stainless Nuts (MN2550000A20000)
(2) M6 Stainless Fender Washers (WC6360000A20000)
Billet Tanks:
The billet aluminum top and bottom tanks look amazing in the engine bay. This design places the radiator hose bung to the right of the engine bay, clearing room for larger manifolds. Two screw-in fitting styles are included for use with either OEM style hoses or -16AN fittings and line.
Radiator Cap:
The top tank does not have a port for a radiator cap. You will need a STM Water Neck for Radiator Cap Relocation. They are sold separately as they are different for Evo 7/8 or Evo 9 models. This places the radiator cap at the highest point in the cooling system. Also it looks awesome. v
Drain Bung:
This radiator does NOT have a drain bung.
Finish:
These will ship with the bare, billet finish as pictured. In the installed photos, the original design is pictured with a custom polished finish. We will have new photos soon!
A/C Condenser Adjustment:
If you still have A/C, the condenser needs to be adjusted forward for a proper fitment. There are two mounting bolts on the top ends of the condenser. Remove the spacer and bolt it back in place using the included stainless hardware. This allows the condenser to sit forward another 1/4 inch. The car pictured has A/C, as installed.
Specs:
• Weighs 11.85 Pounds
• 28 5/8" Wide
• 19" Overall Height with Mounting Posts
• 17 1/4 Height Tank to Tank
• 1 3/16" Core Width
• 1 5/8" Tank Width
Features:
• Billet aluminum top & bottom tanks
• Interchangeable outlets for OEM or -16AN lines
• Relocates the cap for a seamless presentation
• CSF "B-Tube" Technology Radiator Core
• 15% more heat transfer surface area over regular oval "O" shape designs
• Shorter 6.5mm fins yield ~25% more tubes and surface area in the core vs other cores
CSF Core:
Utilizing a custom-sized CSF "B-Tube" Technology Core, this radiator employs thinner and lighter aircraft-grade special clad aluminum material for enhanced cooling efficiency and "dual liquid laminar flow." The unique CSF "B" design surpasses conventional "O" designs in strength and increases the heat transfer surface area of the tube by approximately 15% compared to regular tubes. This technology sets a new standard in high-performance radiator cores, with CSF being the sole aftermarket radiator manufacturer employing it.
The "B-tube" design, unlike regular oval-shaped "O" type radiator tubes, is meticulously engineered and brazed over the seam for sealing. This design allows CSF to utilize thinner and lighter aluminum material without compromising strength, resulting in improved cooling efficiency. Moreover, the inlet in the middle of the tube, which is seam brazed, further enhances heat transfer surface area, providing the efficiency of two smaller tubes within the same space criteria and enabling "dual liquid laminar flow."
Crafted from aircraft-grade special clad aluminum, these tubes undergo intricate formation on the CSF high precision 6-stage tube forming mill. This exclusive technology sets a new benchmark for high-performance radiator cores, distinguishing CSF from other aftermarket radiator manufacturers.
Additionally, the CSF "B-Tube" Technology Core features a high-performance multi-louvered fin with a smaller 6.5mm fin height, in contrast to the 8mm fin used in most standard radiator designs. This design choice results in approximately 25% more tubes and surface area in the core compared to other radiator cores.
