Battery Breather Vent Hose Joiner Barbs.
These insert into the vent holes of an appropriate battery. A number of batteries suitable for use in the NA and NB models aren't supplied with them. This leaves no way to connect the breather vent hose that was supplied in the MX-5 originally.
It is essential to connect the vent tubes as it allows the battery to vent any hydrogen fumes out of the boot.
Two joiner barbs supplied.
Supplied FREE when SSB Battery is purchased in-store at MX5 Mania.
Suits Mazda MX5 NA/NB 1989-2004
