How to change or replace an air filter on a Harley-Davidson Sportster motorcycle

Description

A diy, step by step video demonstration on how to change or replace an air filter on a Harley-Davidson Forty-Eight Sportster motorcycle with K&N filter.

Transcript

This is a video sharing a replacement of a stock Harley-Davidson Sportster air filter with a K&N air filter.

I'm also going to be replacing the Harley Sportster 48 air filter cover with the iron air filter cover.

To replace the air filter I will be using a 3/16 hex wrench, a t27 Torx or star wrench, a flathead screwdriver, because I am replacing the stock air filter with a K&N air filter along with a torque wrench that you will see later in the video.

As you can see here I'm going to be using electric tools although only hand tools are needed for this.

The pleats on the stock Harley-Davidson are much more than the pleats on the K&N, which means that there is a greater surface area.

The other thing you'll notice is that the wire mesh is aboutthe same size.

Although the increased amount of pleats offers an increased amount of surface area, the less amount of pleats in the K&N along with the filter material do create a higher flow.

For those concerned about oil and the K&N air filters, it should be noted that Harley-Davidson Screamin' Eagle brand also offers K&N in their performance parts, as well as considering the two ports that recirculate the engine oil directly into the air filter regardless of its stock or if it's K&N.

Although the K&N air filter does provide a gasket, I did create an adhesive with gasket maker to hold the gasket in place.

Since I am using a power tool I will start each fastener by hand.

The torque specifications for the air filter cover are 36 to 60 inch pounds.

The air filter 40 to 60 inch pounds. I have set my torque wrench to 50 (inch pounds) for both.
