This is an stronger alternative to OEM hoses! These hoses have 3 or 4 PLY reinforcement depending on inner diameter compared to OEM hoses that mostly have 1 PLY reinforcement. Another advantage of these hoses are the silicone material that withstands high temperature for long time.These hosekits are a terrific upgrade if your original hoses start to crack from age or maybe you use your car in a way that the original hoses where not designed for.This hose kit is available in three different colors Blue / Black / Red. There are no performance difference between the different colors, choose which color you think will be best for your car.Please note that you will need to reuse the original hoses metal connections. Use a hacksaw to cut of the metall sleeve. The metal connections will have to be installed with a regular hose clamp on the silicone hose. See the extra product photo.
