Industry first (and patent pending) DOHC EJ Cylinder 4 Combustion Chamber Cooling kit increases coolant flow in the LH head to improve reliability by reducing detonation causing hot spots, reducing EGT delta and improving overall cooling system performance.
Each kit contains:
1x Coolant pipe assembled with a high grade silicone hose, Stainless Pinch clamp, Custom machined and anodized 6061 fitting.
1x Plastic 5/8 T (recommended for all coolant types)
3x 316SS or 304SS embossed worm clamps (subject to market availability)
1x Instruction Sheet
Optional SS T should be used with Subaru's Blue coolant and is not recommend for cooling systems running green coolant due to potential corrosion concerns. I run the plastic T in my own cars.
Cooling mods are available from many online retailers: IAG, Six Star Motorsports, MAPerformance, RallisportDirect, Import Image Racing and many others carry this modification. If I am out of stock, please feel free to purchase from them.
Fits all years and models except 2010+ LGT.
