Why Do We Use & Recommend Jagg Oil Coolers?

HyperFlow Technology is the engineered balance between performance and flow. It should first be described as a "systems" way of thinking.

Air flow, fins, oil flow, turbulators, brazing technology, metal finish, oil filter adapter design, thermostatic actuator, etc., are each components maximized to contribute to the overall system. It is only when each individual component is considered in relation to its contribution to the whole that a true systems approach can be claimed.


Frequently Asked Questions:

At what temperature does the automatic thermostatic by-pass operate?

The actuator begins to move at 185ºF. By 195ºF it is fully-actuated, plugging the by-pass hole, and directing 100 percent of the oil's flow to the oil cooler.

Which direction does oil flow in these oil coolers?

There is no "In" or "Out" on Jagg oil coolers. Whichever port the oil enters, it exits the other one.

Why do I need an oil filter adapter?

Oil filter adapters provide an easy way to access the motorcycle's oil supply for the installation of an oil cooler. Jagg oil filter adapters direct oil through the filter first and then to the cooler. This is especially important on the pressure side of the engine. This allows the warmer, thinner oil to flow easily across the oil filter, and then on to the oil cooler, and then send clean, cool oil to the engine.

Customer Reviews

Excellent product Review by Oil Cooler
After Riding through Texas during record high temps I knew I needed to keep my engine cooler than the cheap stock cooler could keep it. The fan assisted oil cooler from DK works great, is larger than the stock part and was fairly simple to install. Im very glad I got it. (Posted on 7/19/2022)
