6. Jagg Fan-Assisted Oil Cooler Kits for Harley-Davidson

You must be thinking why are there so many Jagg products on our list? No, it’s not because we are biased towards Jagg and it’s not a paid promotion either.

The reason behind there being so many Jagg products is simply that their products are of the highest quality.

Oil Cooler for Harley Davidson Buying Guide

The best decision is an informed decision. This is especially true when you are getting a product that’s highly dependent on technicalities. For example, oil coolers for your Harley-Davidson are different from stuffed animals for your kid. What we are trying to say is that you need to keep some very important factors in your mind when getting the best oil cooler for your Harley-Davidson. Here are those important factors:

Fluid Compatibility

Most Harley-Davidson models use the same oil for the stock engine. But some Harley engines run on different oil than the other ones. So you need to check the cooler specifications to know for sure that the cooler runs on the fluid you are running on.

Of course, if the cooler is specifically designed for Harley-Davidson and your model is included in the compatibility list, then you don’t need to worry about this. Fluid compatibility is also important when you are buying universal transmission coolers or coolers that aren’t specifically designed for Harley-Davidson.


The design always matters to us Harley lovers when we are buying some aftermarket parts for our Harley. But the design doesn’t matter that much when you are going to buy an air cooler, because most of the designs are very similar and have a minimalist look that goes with any design.

If you wanna get something that looks fancy by throwing in a few extra bucks, then feel free to do so. But be careful of getting something too fancy that might not offer you the performance you should get at the price you are paying.

Cooling Performance

This is the most important factor that you need to keep in mind after you have made sure that the cooler works with your fluid type. Cooling performance means how much temperature is reduced by the cooler compared to the stock cooler by Harley. The more the temperature is reduced, the better the performance and the lifetime of your engine. It’s that simple.

You might need a higher reduction in temperature depending on your need. If you are someone who uses their Harley for a long time on the whole day or someone who travels from one city to another regularly, then a higher cooling performance can do wonders for you. Your engine will love to be in a cooler temperature and give you better performance on the road.

Final Note

We have tried to cover all of our bases in trying to give you a buying guide to the best oil cooler for your Harley. We have left out some small features and specifications here and there. It’s because we didn’t think those features are that important to be added.

If you want to know about our top pick from this list of 7 products, it’s the Jagg Fan-Assisted Oil Cooler Kit. This cooler is simply amazing even after being a relatively higher-priced product.

The value you will get is amazing, and the design will instantly catch anyone’s eyes. If your budget allows it, you should walk home with this product without a second thought in your mind. We hope you get the best cooler for your Harley after reading our article.
