Buying Guide Of Air Intake For Harley

Everybody wants their bike to have increased horsepower and improved performance. The air intake filter can give you all of those things when you upgrade, or when you simply install a new one.

Before you buy a new air intake filter look at the following things that our mechanics suggested you consider. This might help you to buy the filter that will be best for your bike, and your style of riding.

The amount of Horsepower gain it promises

If the main reason for upgrading your air intake is to gain more horsepower on your bike then pay close attention to the amount of increase the filter claims to provide. A good rule of thumb is to depend on slightly less horsepower gain than what the manufacturer claims the filter will provide.

They are not lying about the gain but they tend to tell you the maximum amount of gain that has been reported and not the average amount of gain.

Is the filter flame retardant?

The best way for you to stop back firing is to install an air intake filter that has been soaked in an oil base product that has a high flash point so the filter is made flame retardant.

Is the filter a lifetime filter?

Some air intake filters are designed to be installed and then replaced after you have driven a specific number of miles. You throw away the old filter and install the new one.

Some filters are designed to never need replacing. After you have driven a certain number of miles you simply remove the filter and wash it.

Installation Specifics

Most air intake upgrades are easily done with very little installation concerns. If you own a Twin Air or a Loudmouth then you might have to remove portions of the sub-frame to get the upgrade perfectly aligned and functioning on your bike.

Just because upgrading the air intake is not hard to do that does not mean to imply that you will complete the task in just a few minutes. You will need the proper tools for the job and a little patience.

Does it meet Emission Regulations in your State

You have to pay attention to the warnings the manufacturer posts about where the filter is not legal to be used. California has strict emission codes and many filters are not legal to be placed on bikes being ridden in that state. If you are uncertain you can always ask a bike mechanic in your area.

Final Note

If you are looking for an air intake filter system that is unique in appearance and capable of making your bike look more aggressive, then we recommend the Krator Black Spike Air Cleaner Intake Filter. This air intake filter is in a cone shape that is fashioned from billet aluminum and painted flat black.

If you are looking for the air intake filter that will provide you the most horsepower increases for your Harley Sportster, Soft-tail or Touring bike then we recommend the K&N 63-1125 Air Intake Kit. This kit can give you as much as a 7.8 HP increase. It will also give you an aggressive look and improved sound.
