This is a stronger alternative to OEM hoses! DO88 hoses have a 3/4-ply reinforcement (dependent on inner diameter). Additional advantages of these hoses is the silicone material that withstands higher temperatures for longer periods of time.

This makes the DO88 hose kits a terrific upgrade if your original hoses have started to crack from age or if you use your car in a way that the original hoses were not designed for!
