Remote Oil Filters Designed For Motorcycles

UPDATE- I now have the necessary fittings for the spin-on adapters and they'll be included at the same price. New pics are all the way at the bottom.

If your bike already incorporates a spin-on filter and you want to relocate it you'll need a spin-on adapter in place of the stock filter. I stock the one shown below, from Derale Cooling Products. It has a 3/4-16 filter nipple (fits 90% of everything out there), is made in the USA and is a bright diecast aluminum finish.

Jegs gets $19.99 for these and theirs doesn't come with the $8 - $10 worth of brass fittings that you'll need. I now have the fittings in stock and they'll be included. With fittings, we get $24.99 for these but JJ members get 20% off, making your price $19.99. If you're buying one of our Remote Oil Filter Kits this will ship in the same box so your shipping cost won't go up any at all.

Filters

A lot of guys have asked for filter recommendations. We like Harley-Davidson's new Super Premium filter or aftermarket equivalents for the following reasons (part numbers will appear at the bottom).

When H-D introduced the Twin Cam motor they also introduced their 5 micron filter intended for use on the supply side of Twin Cam motors. A lot of people tried those filters on earlier bikes where the filter is located on the return side and the results were not good. Those early TC filters were too restrictive to run on the return side of earlier bikes and caused wet-sumping in many cases.

The new Super Premium filters were designed for, and work on, all of them. They filter down to 5 microns, but are free-flowing enough to run on the earlier stuff. They flow 7 -9 GPM and do have an anti-drainback valve. They also incorporate an 8 PSI bypass. This doesn't mean that they will bypass if your bike makes more than 8 PSI oil pressure. This means that they will bypass if there is 8 pounds or greater of pressure drop across the filter, meaning the filter is becoming clogged.

The aftermarket equivalents must meet all the same criteria to be listed as a replacement for the oem filter. That doesn't necessarily mean they are or are not of the same quality, just that they meet H-D's specs outlined above.

Sorry for the long read. I just want to give you guys as much pertinent information as I possibly can.

Kind of a gritty picture, only used two of the three bolts and reamed the holes just a little.
