You will not find an oil cooler that offers the combination of durability, performance, and flow of the Jagg oil cooler at any price. It is this combination that has allowed Jagg to remain the choice of TOP teams and builders across all venues of motorsport.

Brazing technology

Generations ago, Jagg was already at the forefront of brazing research and development. The brazing process itself is the variable most often overlooked when considering performance of an oil cooler, and it is our continued brazing research and development have allowed Jagg to remain the leader in performance and reliability. While competitors are brazing aluminum oil coolers merely as a method of construction, Jagg's blend of experienced craftsmen and technological methodology allow this step to afford an even greater performance advantage.

Internal design

Jagg Oil Coolers employ an in-line turbulator to gently stir the oil, ensuring that the oil is exposed to the entire internal surface area of the oil cooler with the least pressure loss. Jagg has been a pioneer of efficient turbulator design. Jagg turbulators are fully brazed to the entire internal length of the tube, resulting in "zero" heat transfer barrier and high strength.

Fin design

The fin is the most considered and most visible cooling portion of any oil cooler. Made in-house to our exacting standards, our fin not only contributes to cooler performance but to durability as well. Jagg fins are fully brazed, resulting in "zero" heat transfer barrier. Each fin section employs precise mini-louvers to further the effectiveness of the air as it travels across the cooler.
