Arlen Ness Stage 1 Smooth Big Sucker Air Cleaner Kit For Harley Twin Cam

Arlen Ness, the "King of Choppers," knows a thing or two about performance. The Big Sucker is the best-selling and most powerful air cleaner kit on the market - period. Simply, the Big Sucker is designed to give your engine maximum airflow for maximum performance. Testing shows that by simply installing a Big Sucker kit, horsepower gains of up to 21% are attainable.

Big Sucker kits feature patented, hidden breather backing plate technology - this means the breathers are incorporated into the air cleaner housing itself. Gone are unsightly external hoses and hardware, giving your bike a super-clean look. Each hidden breather has a sealing O-ring at the heads and exits at the carburetor or throttle body inlet to provide efficient internal engine pressure relief. 

The Standard air filter elements are made one at a time using the finest materials available. Standard filters are all pre-oiled, and feature four layers of surgical-grade cotton to promote airflow and filter air effectively.

The Synthetic Stainless Jacketed filter features a synthetic material that is water resistant and never needs to be oiled. Just wash and re-use. The mesh supporting the gauze is made of a rust-resistant stainless steel as opposed to standard carbon steel, and the synthetic filtration gauze is in black or dark grey, rather than the pink/red hue of the Standard Filter.

The filters are hand-poured one at a time in a urethane body, unlike many other filters that are spun, which can leave a residue on the filtration media.

All kits include a Big Sucker backing plate, high-flow filter, chrome banjo bolts, gasket, hardware, and simple instructions. 

Note: Air cleaner images are for reference only. All kits on this page will include filter of your choice.

Note: 1999-2001 Touring models equipped with Magneti Marelli EFI require Arlen Ness Smooth Stage 1 Big Sucker Air Cleaner Kit For Harley Touring With EFI 1999-2001.

Arlen Ness Smooth Stage 1 Big Sucker Air Cleaner Kit For Harley Twin Cam 1999-2016 4.9 5 25 25
Breathe Better - $$ and Perfomance Not only do you get the best bang for your buck, but this Big Sucker combined with Dynojet Power Commander V enhanced performance for my Dyna. Not only can you hear the difference, you can FEEL the difference. August 16, 2016
Easy to install. Looks great! The air cleaner was very easy to install. The wrinkle black finish looks great. My bike seems to run smoother now and has just about lost all of the decel popping that I would get after I upgraded other parts on my bike. The only negatives were that it appears that some of the hardware included with the kit was missing or not correctly sized. The bolt for that holds the cover to the filter itself was not long enough to engage the threads on the backing plate. Instead for my install I ended up using bolt that was part of the OEM air cleaner hardware. Other than that I'm very happy with the look and performance I have gotten since this upgrade. July 15, 2016
Love it! Product works great, priced right and came exactly as advertised - quickly too! July 5, 2016
Beautiful and effective The filter is awsome: i bought the one with crome cover (unfortuntely the bolt to fix the cover was missing from the package) and it gives a great look to my Street Bob. But most important it changed the sound of aspiration : it's deeper and you really can feel those two pistons avidly sucking air. Go full throttle and will hear your engine pulse live. Completed my settings with a V&H FP3 ... my better spent money on a bike ever. June 28, 2016
Clean look, increased airflow Great replacement for the intake on my Streetbob. My number one complaint is the quality of the hardware they provide- IT'S JUNK! I was HAND-TIGHTENING some socket set screws on the baseplate when they snapped in half becoming jammed in the baseplate. Trying calling Arlen Ness- couldn't get through to anyone. Waste of time. Tried calling a local shop to see if they had literally two screws- nope. Tried Lowe's/Home Depot- nope. Tried mom and pop hardware stores until I found QUALITY hardware. Only problem is I could only buy a box of 100, and I needed just two. Came home, extracted the broken screws, replaced them all with quality hardware, and finished the installation. Bike runs smoother and has a snappier throttle response. May 17, 2016
Great fitment Product is great and fits nice. The cover it comes with looks cheap but my stock air cover fits great which is better to protect against the rain and other elements 2015 Harley Street Bob also with the stock cover it doesn't show that you have an aftermarket product so in California you don't have to worry about getting a ticket May 10, 2016
nice great value works well down side is that you may have to change the brake lever as it sticks out quite a bit. i bought a shorter one and highway bars and pegs April 28, 2016
great air cleaner awesome product looks good and works well. great buy April 13, 2016
