8/16/20v 4age/fe- Oil-filter spacer elimination union

Description

8/16/20v 4age/fe- Oil-filter spacer elimination union

 

Compatible with all Toyota A-series engines this simple part lets an oil filter fit directly up against the engine block itself. In addition to a neater look with easier access it also increases the oil filter to exhaust manifold clearance and hence the filter is subjected to less heat from the exhaust system.

 

20V 4age engines originally are fitted with a bulky housing between the engine block and the oil filter. Aside from mounting the filter further outwards these housings are hollow and perform no other function. It can only be presumed that this is to raise the filter purely for better access. However in a rear wheel drive install or without a power steering pump in the way there is no need for such a thing.

 

They can also be used to remove any inline sandwich plate from between the oil filter and the engine block such as those used by oil coolers.

Installation guide

To install this part unbolt and remove the original housing / sandwich plate along with all of it’s fasteners, none of these parts are required to be re-used. To help fit these unions in place they feature a 12mm internal hex profile. They are wound into a block until bottomed out.

These do not require to be tightly wound into place. As such they can be either hand tightened or if desired tightened further with tools. If so then there are a few easy options:

– 12mm Allen key

– A bolt with a 12mm head (Some M8) held upside down with the bolt head fitted into the union’s hex socket and wound in via the tail end of the bolt.

– A protective rag wrapped around the union and then the outside grabbed with multi-grips to turn.
