Note: Some types of coolant are not compatible with silicone hoses. Please click here to download our Important Fitting Notes before buying and fitting silicone hoses.

This high quality silicone hose kit replaces the brake servo to inlet manifold vacuum hose. The stock hose has an internal one-way check valve to maintain vacuum in the brake servo, this kit includes a new one-way valve to retain proper brake efficiency from the servo. This kit fits all right hand drive (RHD) MK2.5 (Facelift) 1.8 MX5/Miata models, it will not fit LHD or MK2 (Pre-Facelift) models.

Hose Clamps:

The kit comes with a full set of hose clamps using the options above. The three types of clamp we offer are shown below, but not all options will appear for some kits due to clamp size limitations:

Stoney Racing Stainless Steel Worm-Drive Clamps, Black Coated Spring Clamps and Stainless Steel T-Bolt Clamps

Spring clamps are the most commonly used type by vehicle manufacturers. They provide excellent evenly distributed clamping force and are generally the best option for clamping coolant hoses, but they can be fiddly to fit/remove, and being mild steel they are more prone to surface rust over time. Whilst this won't affect the performance or lifespan of the clamp some customers prefer our stainless steel options below which tend to look better and still perform as they should.

Worm-Drive clamps have slightly less evenly distributed clamping force as the Spring type clamps, but they are still a good quality clamp and usually easier to fit/remove in the tight confines of an engine bay. Being 100% stainless steel they do not rust, so we recommend this type of clamp if you are concerned about the appearance of your engine bay.

T-Bolt clamps * Not available for this product *

For some vehicles the original clamps can be reused so we also offer our kits without clamps, but please be aware our silicone hoses are slightly thicker than the standard hoses so in some cases the original clamps may be too small.
