MX-5 NB Silicone Coolant & Breather Hoses

Looking for a complete, high quality, ultra durable, long lasting and high temperature resistant silicone hoses set for your Mazda MX-5 NB (Mk2) engine? We got you covered!

This complete silicone coolant and breather hose kit consists of 10 hoses (for 1.6 engine) or 13 hoses (for 1.8 engine).
