RB20/25/26 OEM water pump
Replace your water pump when doing your timing belt. It sits behind all of the timing components, and they all need to come off to access it. The water pump is fairly cheap in cost. It would be a shame to finish up the timing belt job, only to find the water pump leaking shortly after - and to have to remove all of the same parts once again to replace it.
Comes with 4 new water pump pulley studs.
N1 water pump is also available, with product description that explain how they differ. Many people misunderstand the N1 pump, so please, read before purchasing to see if it's ideal for your application - you may be surprised.
