I bought my Big Sucker Stage 1 two weeks ago and installed last weekend. The installation was simple. I had a few questions regarding the installation and went to the Arlen Ness website to see if they had anything. There is an installation video that walks you through all steps involved.
You can use it without a cover or with the OEM "football" cover. It will also work with the OEM covers offered by HD.
Recommend this product for anyone wanting a cheaper air cleaner that does a great job!
I changed out the air cleaner on my 2012 Fat Boy with this one and it made a huge difference. Not only in performance, but in making it run cooler. The old one got really hot, this one gets more air flow and stays cooler.
I put this air cleaner assembly on my 07 Nighttrain, and with the pipes and fuel tuner it sucks in ALOT of air and helps to bring my performance higher than I thought an air cleaner could do. If you want easy install, great looks, and best bang for your buck this air cleaner assembly is it.
The Big Sucker Air Cleaner Kit (18506) fit perfectly onto my 2003 Harley-Davidson Fat Boy EFI. I noticed an immediate difference. Engine runs like it just got a breath of fresh air! Before installation it sounded like it was suffocating to death. Throttle is more responsive on acceleration. It was also easy to install. Definitely worth the purchase!
I purchased this assembly in conjunction with a Cobra fuel processor and a set of V&H Shortshots. It took less than 10 minutes to install and looks great and really pulls in the air. And a big plus is that it uses the stock air cleaner cover so there is no need to purchase any extra covers.
