$199.00

Do you want your NA or NB MX-5 to not only run cooler, but to look cooler too? Then our improved premium reroute kit with colorful silicone hose and black anodised plates is just the thing for you.

This premium kit gives you all the customization options you want:
– reroutes the cooling path to protect your engine,
– allows you to run aftermarket coolant temperature sensor,
– lets you delete the front coolant neck to de-clutter your engine bay,
– offers possibility to delete your cabin heater.

And on top of all this, you get the high quality bespoke silicone hose. Compared to rubber, silicone hoses last longer and better resist cracking and heat (up to 160°C).

– Coolant will flow in the original path like it was designed for Mazda B6/BP engine.
– All kits include an additional 1/8″ NPT thread for sensors.
– Original sensor placement and coolant bypass circuit allow for coolant flow while the engine is cold, assuring proper warm-up.
– Installation takes just a few hours without the need to move or remove the engine.
– If you wish to uninstall the reroute kit, keep the original parts and everything is fully reversible.

Everything you need for the installation is included (except for EGR delete/Front coolant neck delete plate – if you car has EGR system, you can get one in our shop). We do sell the coolant block off separately, the included coolant block off will delete the neck all together and is intended to go right onto the cylinder head port. All coolant systems like cabin or intake valve heating are retained. If you opt for neck delete option you get a core plug securing plate with a hose joiner for the intake (IACV) hoses.

NOTICE: These have been on a revolving backorder due to the rate at which they can be manufactured. Not a huge delay in most cases, expect a week or so lead time unless you call to check stock firs.

    Finally. A legitimate reroute kit

    This is apparently a new kit that Fab9 put together - I ordered the Hawley version awhile back and they sent me the new version. SUPER NICE. Way more complete and installed nicely. A lot of little pieces included that aren't necessary but a nice touch.

    With FM throttle body coupler you definitely have to modify around it.
