AMSOIL By-Pass Filter Installation

1991 BMW M3
AMSOIL Dual Remote By-Pass Filter System
Submitted by AMSOIL Dealer Mike Swale

BMK-14 remote filter, with (2) 45° and (2) 90° fittings installed on a 1991 BMW M3 with a 2.5l S14 engine

Since I upgraded to the DTM intake, it was hard to do oil changes. The intake plenum would have to be removed since the oil pan and oil cooler lines are in the way. There is simply no way to access the filter from below the car.

Now oil changes take 10 minutes instead of the 2+ hours. Did I mention NO mess?

Installation was simple. Measure twice cut once. It did take a while to figure out what extra fittings that were needed. The kit only comes with straight fittings. This made it hard to mount it in the cramped engine bay. You want to keep the hoses as straight as possible. Thus the need for 4 extra fittings. (2) 45 deg° for the oil filter housing, and (2) 90° for the engine block filter adapter. The hoses are about 18” long.

All in all I was very happy with this kit. I noticed that my oil temps are a few degrees less and now I run a higher capacity oil filter. This makes less of a pressure drop in the filter. It should catch more particles and flow more oil, always good on a very expensive engine.

One word of caution. The filter will get VERY hot, and should not be touched once the engine is driven. Putting it in a very easily accessed point, it woke me up once or twice.
