Replace your old, dried out factory radiator hoses with the COBB Tuning Silicone Radiator Hoses. Constructed of 3-ply reinforced silicone, these hoses will not only look better but also last longer. Silicone hoses have a higher operating temperature range, making them a must for any car that may see extended periods of aggressive driving or track time. COBB branding is found at both ends of the hose.

Reinforced silicone hoses have a higher temperature operating range, are more resistant to chemical reactions, and maintain their flexibility through a longer lifespan than factory rubber hoses. They happen to look much better, too.

Great quality hoses for the price

I was in the market to upgrade to silicone hoses while I had my coolant vacated for a timing belt change, and between a few bucks in price and the placement of their logo, I was sold on these over the few others I was looking at. I'm not sure if this CAME from Subimods as it arrived in a Cobb box with Cobb identifiers as well as a free plate frame and a few white (about 6") vinyl logos looking more like a drop ship, but I was as impressed as always with the shipping speed and quality of packaging when ordering from Subimods. As for the hoses themselves, the upper is kind of a given, but the lower can go one way or the other. One way was binding a little at the bends so I switched it around end for end and it went on a little better. Still trimmed about an inch to get it perfect but they fit great and went right on. I thought they would fight me but nope. Slid right on.


Thank you for your 5 Star Review! I am glad to hear that you are satisfied with the quality of the COBB Silicone Radiator Hose Kit and the shipping and packaging from Subimods. It's great to hear that the installation of the hoses was easy and that they fit well, despite some minor adjustments. We hope you continue to enjoy your purchase!

We appreciate the 5 Star Review!



Hoses were a little too long, but managed to make them fit.


The OEM rubber radiator hoses dry out and crack creating leaks which is never good for you cooling system. The COBB Silicone Radiator Hose Kit is a perfect upgrade and replacement! The reinforced silicone hoses will last longer and look better too! Thank you for the 5 Star Review!
