I spent the money for a Mishimoto radiator. I didn’t want to compromise on the hoses, so I bought theirs. They are an exact replacement, and have a lifetime warranty. I’m a rather fugal senior citizen, but wanted to KNOW I got the best. I think I did it right.

This hose is amazing! Uograding to silicone and having a hose that has less wear points or fail points as original manufacturer. Must buy!
