Have you ever found yourself wondering why your motorcycle needs an air intake? It works to bring oxygen to your motorcycle and allows it to mix with the fuel. For all internal combustion engines, more air results in more power. Your motorbike’s air filter and airbox allow clean air to enter the combustion chamber and provide power, ultimately allowing your vehicle to move with ease.

Our Top 3 Cold Air Intake for Harley-Davidson

Now, you must be wondering about the added advantages of having a cold air intake system installed in your vehicle, aren’t you? Let’s have a look.
Perks of Having a Cold Air Intake System Installed in Your Harley-Davidson
- Air intake is directly proportional to horsepower. Cooler air is denser – meaning that a cold intake pulls in more air per unit of volume, leading to good power gains.
- The air intake system comes with thick filters that are better and more sustainable than paper filters – they can be cleaned easily over time.
- If you love the sounds of revving engines, you will be happy to know that this system will further amplify the sound by giving it a smoother, full-bodied character.
- All of this adds up to greater acceleration as well.
1. K&N Cold Air Intake Kit – Best Overall
Does filter cleaning seem like a tough job? With this K&N product, you can go on for 10,000 miles without worrying about it! To top that, your engine is going to be protected from contaminants. This product has been dyno tested which ensures an increase in horsepower and torque. Airflow is said to be more than 50% of the regular restrictive factory box air filter and the intake tube which is made of cast aluminum.
The better towing allows improved uphill performance and enhanced acceleration. This kit has a long life of around 10 years, provided that you stop to maintain it regularly.
K&N could come off as a big fit for your motorcycle, but not for all models.

Frequently Asked Questions
The K&N Cold Air Intake kit, 57-1137 is not compatible with the 2014 Harley-Davidson XL883N IRON 54 CI
Unfortunately, the High-Performance K&N Cold Air Intake Kit 57-1137 does not include a rain sock or a pre-filter.

One must understand that there exists a relation between air restriction and mileage. The amount of work an engine has to perform to suck air through the intake tubes and air filter is directly related to the gas consumption. However, this does not necessarily mean that one will experience a change in the mileage.
But yes, K&N also does not state either that installing their air filter will definitely improve the vehicle’s mileage. Many variables affect mileage such as tire inflation, the type of fuel, weather, elevation, the speed at which you drive, the gear in which you drive, etc.
The other factors are- the speed with which you accelerate, engine maintenance, excessive idling, cruise control, the grade of motor oil you use, and of course, the condition of your air filter.
K&N guarantees that all their intake systems are dyno-tested and they will increase your vehicle’s horsepower. But, instead of making a general claim, K&N publishes estimated intake system horsepower for many part numbers and vehicles.

3. Lingdu Air Cleaner Intake Kit – Best Budget
This air cleaner intake kit is produced by the brand Lingdu. This fit type of this Air Cleaner is vehicle specific and the material with which it is made is aluminum. However, there are a few things that one must pay attention to. Firstly, the air cleaner fits into the cable throttle only with Delphi Fuel Injection or CV Magnetti- Marelli fuel injection equipped models.
The brand assures you a warranty of 60 days from the date of purchase, so you can get in touch with them if a problem occurs. Models that are well-suited for this air intake kit are:
