Imasen B5B4 relay as fitted to the Mazda MX5 MK1 / MK2 / MK2.5 / Eunos 1989 - 2005 as well as Mazda 323, 3, 6, 626, Premacy.
There are two types of B5B4 - This listing is for the Black top with wider fitting. If your car has a B5B4 with a green top and bottom with a narrower fitting do not buy as this part will not fit. If you have a colour preference, green or white bottom, please add a message when you checkout. They both have the same function so if I don't hear from you the nearest part to hand will be sent out.
This is the fuel pump relay on the MX5.
Guaranteed to come to you in good working condition.
I have every conceivable relay for the MX5 / Eunos MK1, MK2 and MK2.5 1989 - 2005
