S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.
Upgrade the intake on your 1999-2006 Harley-Davidson Twin Cam Softail with the S&S Cycle Air Cleaner Kit. This high-flow design is engineered to deliver a significant increase in airflow, allowing your engine to breathe more efficiently. Experience improved throttle response and a noticeable boost in overall performance.
The S&S Cycle Air Cleaner Kit for 1999-2006 Harley Twin Cam Softail models is built to uncork the potential of your V-twin. It features a robust die-cast aluminum backplate and a washable, reusable filter element, designed for longevity and consistent performance. The radiused inlet and S&S stinger geometry are key to smoothing the air path, ensuring a denser, more consistent charge into your cylinders for optimal combustion.
This S&S air cleaner is designed for riders looking to get more out of their Twin Cam Softail without extensive modifications. Its bolt-on nature means you can quickly upgrade your intake system and immediately feel the difference. For those seeking even greater airflow, S&S offers a higher-flow filter variant separately, allowing for future customization and performance tuning.
Will this air cleaner fit my 1999-2006 Twin Cam Softail?
Yes, this S&S Cycle air cleaner kit is specifically designed for 1999-2006 Harley-Davidson Softail CVO models and other Twin Cam Softail bikes within that year range.
Is the filter element reusable?
Absolutely. The filter element is washable and reusable. We recommend cleaning and re-oiling it periodically with standard filter service products to maintain optimal performance.
Do I need a custom tune after installing this air cleaner?
While the kit provides a measurable increase in airflow, a proper dyno tune or fuel management system is highly recommended to optimize air/fuel ratios and maximize the performance gains on your Twin Cam engine.

Very pleased with everything in this Kit! The cams were exactly what I wanted. Almost like stock to about 2500rpm and then it really turns on when you nail it! Made the old Fatboy spin the tires hitting 2nd and a little in 3rd!
It's definitely worth the price. If you have a little know how you can install it in a couple of hours. The bike is definitely faster. The only drawback with the kit is you should be able to pick the cam that you want instead of having to choose from just the couple of cams that are offered with the kit. Overall still an excellent product and kit.
I was impressed with the shipping, quick and easy. I purchased it as a gift but I ordered the wrong item. Getting a refund was just as painful as ordering. Yes I would recommend this company first.
not a complete kit. does not come with new cam chains. was told to use the old cam chains. putting in new tensioners and told to use old parts? will not buy S&S kits again.
Great street cam. So much better that factory Harley-Davidson performance !!
Great product. My motorcycle is ripping now
