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).

It’s available in multiple colours and with optional stainless hose clamps. Since the silicone hoses are more durable / thicker than the stock ones, using our hose clamps is advised.

The hoses are made out of 4.5 mm thick four ply silicone with three ply polyester reinforcing. They can withstand up to 7 bars of constant pressure (10 bars of burst pressure) and temperature from -50°C to 240°C. These hoses are manufactured to a high standard and with compliance to ISO9001:2000 & ISO TS16949 norms.

Set fits MX-5 NB (Mk2) 1.6 (B6-ZE) and 1.8 (BP-Z3) engines with manual gearbox, both left and right hand drive versions. Please select your engine version and colour prior to ordering.
