One of the biggest issues with a turbo install on an MX5 is space for all the plumbing required. The lower radiator hose, power steering lines, the turbo oil drain and the charge pipes may all be trying to occupy the same space. Our lower radiator hose helps alleviate some of these fitment issues by keeping the coolant close to the block, leaving much more space for the rest of the hoses.

This is a high quality rubber hose manufactured by Dayco.

Fits all NA and NB models, fully compatible with power steering.

Note, the hose can be trimmed further at the water outlet side bringing it even closer to the block.

*Note – This is best used with aftermarket (42/50mm core) radiators, as the additional 20mm or so they provide is required in order to use this hose. We would not recommend a turbo build without an upgraded radiator.

    This product is not suitable for stock MX5 radiators, it will fit if you feel brave stretching the hose more than I felt comfortable doing so. What has been more disappointing for me is BOFI racing support, upon reaching out to them for advise they told me they fit this product on MX5’s with larger rads that sit 20mm closer to the engine. I can’t see this mentioned anywhere in the advert, and they have offered nothing else to help resolve the issue.

    Pros – good quality hose, probably would do an excellent job if it fits

    Cons – would not recommend with stock radiators

    Good Product helps a lot with boost pipe clearance. As mentioned you need to stretch it quite a lot, but it worked for me… Get some proper hose clamps for it because neither the stock ones fit nor do cheap ones do the job because you need to clamp these pretty tight to stop them from leaking.

    Even with an aftermaket core with the required thickness (42 mm) the fitment is very minimal. I could not get it to sit properly without stretching it further than my liking.
