Frequently Asked Questions.

Answers to the questions we’re asked most about sizing, fitment and performance.

Still can't find your answer?

Contact Us

What is it, and what does it fit?

A complete set of silicone hoses for this Mazda, made to the correct bores, lengths and bends so each piece drops straight in. Check the model, engine and year range on this page against your vehicle before ordering.

How do I make sure it fits my car?

Match on model, engine and year or facelift, because hoses often change mid-generation. The most certain method is the OE part number on the part you are removing. If you cannot find one, send us photos of the old hose with a tape measure alongside, or your registration, and we will confirm.

Why replace the original?

Original rubber and plastic parts perish, harden and crack with age and heat cycling. Silicone does not perish and handles far higher temperatures, so on a part that is awkward to reach, fitting silicone once is considerably cheaper than doing the job twice.

Does it come with clips?

Some of our listings offer clips as an option at checkout - check the options on this page. Where they are not included, we stock stainless worm drive clips and T-bolt clamps in every matching size. Always renew clips with a hose: old ones lose tension and corrode where you cannot see.

Is fitting a kit a big job?

It varies by vehicle - a coolant hose kit means draining and refilling the system and bleeding the air out properly, which is the part people underestimate. Allow more time than you think for access to the hoses behind the engine, and have fresh coolant and clips ready.

What if my exact model is not listed?

We manufacture bespoke silicone hose to order and make one-off parts regularly. Send us the old part, a sketch with dimensions, or an OE number, plus what flows through it and the temperature it sees, and we will quote. Small quantities are welcome.
