Special Instructions:

The attached pictures (see below) are of a BMK-13 installed on a 1990 BMW 325is with the 2.5 inline 6 cyl. gas engine. The "shelf" where the mount sits is part of the stock configuration on the 6-cylinder cars. The only additional parts needed were a strip of metal and an elbow to run the lines through. Both of these were purchased at Home Depot and came to less than $15.

The strip of metal was bent into an L shape on a bench vise and cut to fit the shelf. One hole was drilled closest to the engine for a bolt and the other hole on the upper end was already in place. Next, some of the left over metal was drilled to accept the mounting bracket included in the BMK-13 and then placed at an angle to allow the filter elements to be spun off without a problem. The other end of this piece was bolted to a support bracket. At the end of the shelf, another support was run out and bolted to the shelf. The bracket is very secure and won’t go anywhere. Since this car will be driven on roadcourses, this was a big consideration.

Since the oil supply and return lines run very close to the exhaust manifold, the rubber elbow was used to help hold them near the firewall as they make the bend around towards the mount. An existing bolt was used for this purpose.

The main bracket that the mount sits on was fabricated in a way that allows the filters to be spun off in place (slightly messy), or after the removal of three bolts, the whole assembly can be raised for a neater approach. There is also sufficient room to get a sampling bottle under the petcock for easy sampling without removing the mount. Overall, I couldn’t be happier with the kit and look forward to using this installation as a showpiece for potential customers.
