Tech – Love Jugs Install (Intro)

Love Jugs says its two-fan device will drop engine temperature of a Harley-Davidson by 100 degrees in four minutes. We put that claim to the test in our Love Jugs install and review.

The first time I heard of Love Jugs I thought it was the title of a porn movie. Okay, so maybe I shouldn’t have told you that. But what I should definitely tell you is that a set of Love Jugs fans provide extreme cooling power directly to your Harley’s combustion chamber and exhaust valve area. For this added charge of coolness, we installed the original Love Jugs Slots system (#SD-320/$399) on our 2006 Road King. Practically, we all know that increasing air flow over an air-cooled engine will lower its overall temperature. Your front cylinder runs hotter than the rear because it’s mostly getting the hot air flowing from the front cylinder. Of course, there’s no air flowing over the whole engine when you’re sitting in traffic on a hot day.

Love Jugs achieves its massive cooling potential by flowing 504 CFM of air from a pair of electric fans (252 each) directly to where it’s needed most, whether the engine is sitting at idle or out on the open highway. Love Jugs are available in a chrome or black powdercoat finish and are made entirely from aircraft-grade stainless steel. The outdoor-rated electric fans are entirely waterproof to the degree that they can actually run underwater. This may seem like overkill to the casual rider, but long-distance riders know how important weatherproof equipment is.

In addition to a cooler top end, Love Jugs, by default, also keeps a Harley’s oil much cooler as well. Cooler, more viscous oil leads to a longer-lasting engine and less wear and tear.

Several different Love Jugs designs are available, as well as vibration dampening options, and come with everything you need for the installation. All Love Jugs models will fit 98 percent of all Harley-Davidsons ever made as long as there’s a horn mount on the left side of the engine. Love Jugs makes some pretty hefty claims about its product, so we decided to do our own test, conducted by Editor Chris, as we reported in an earlier issue and have included in this article in an accompanying sidebar. If you’ve been looking for a way to improve the cooling of your Harley-Davidson, check out the step-by-step install to see exactly how to make that happen!

Love Jugs installation

Using a 1/2″ deep socket, remove the acorn not that holds the stock horn to the bike. Then pull the horn from its ribber vibration isolator.

We installed the chrome Love Jugs nameplate assembly to the stock horn bracket using some blue Loctite and a 1/2″ socket.
