Arlen Ness Stage 2 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 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.

The Stainless Jacketed Filter differs from the Standard Filter in two areas: 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.

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

The Stage 2 kit differs from the Stage 1 by including a 20% larger air filter element.

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

Can hear the difference
I can hear the sucking power of this Intake even at highway speeds. This had noticeable differences in throttle response and power of the bike. Would highly recommend this to anyone looking for a good looking intake with performance to boot.

Great buy
Bought this for my 07 wide glide and it looks and works great, although only one bolt hole lined up to hold the filter on. It's pretty snug though still. Sounds good when you give it some gas. It definitely takes a lot of air in. My knee rubs on it but not bad enough for me to care.

Legit simple classic look
Low price, nice clean look I read that the size of it could get annoying but I've got fairly long legs I'm about 6ft and it doesn't bother me the least bit. Although I am aware my leg is touching. Sounds cool hearing the air get sucked in since it's so big.

GREAT PURCHASE! LOOKS KILLER!
I rocked the stock Air Cleaner and while I did not mind it, it looked, well "stock". Was initially looking at RSD cleaners but at $400+ no thank you. This fits the bill of price wise without having to sacrifice quality of product. Half the price of RSD and gives my bike a more custom/rod look. I've gotten numerous compliments on it since!

Some reviews say since its much larger than most, it may be uncomfortable. Depending if you're riding highway pegs or forward controls this may be an issue for some but I never found it one. Still comfortable to ride!

And as for the cover, very well made and sturdy!

Great all around upgrade.
If you're considering a Stage 1 upgrade, this is a great air cleaner to consider. Good band for your buck, classic not overly flashy styling. This will also fit under most stock covers.

Can't go wrong!
Bought this for my 04 HD Springer Softail (FXSTSI) with the hopes to increase power and give it that old school look. I'm more than satisfied with the results. Revzilla had it on sale for lower than anyone else and it shipped ridiculously fast. Ordered it Wednesday afternoon and it arrived with Fridays mail. The Big Sucker looks great and doesn't interfere with my leg while riding. I obviously will recommend installing a fuel tuner or super tuner to get the most out of your bike seeing that you will run lean, more so than from the factory. Overall great product, excellent price, and amazing service from Revzilla.com.

increase intake for Fat Bob
I recently installed the Arlen Ness Sage 2 Big Sucker intake. It is a simple installation and definitely increased intake.

The only issue was the bolts for mounting filter were too short, these were 1/2" in length and would not reach the backout bolts. Unfortunately I did not discover until 80% installed...I ran over to local hardware to purchase 1" length bolts. Fit perfect.

Revzilla did give me some Zillacash for my inconvenience.

Overall a good purchase and it looks/performs good on my bike.

Performs well, looks good
Very pleased with the performance. More horse power from the better air flow is obvious. The filter itself is holding up well t the Texas dirt and sand.

looks great - a bit wide
The breather systems looks great, gives my 2001 dyna a bobber style look which I love, the only downside is that it sticks out really far making an awkward angle for my forward highway peg (my foot is 1/2 off the peg if its straight). I just ordered a set of longer pegs which will hopefully be able to compensate for the wider breather system.

will i need a sock if riding in the wet?
Kris P on Apr 21, 2016
BEST ANSWER: You'll need something to cover the forward side and top.
I have a 2013 fat boy lo and I put rinehart 2 to 2 churchill exhaust and a stage 1 air cleaner. I am looking at putting vance and hines big shot staggered on. I will also put the v & H fuel pack on as well. I am wondering if I put on the Arlen Ness Stage 2 air cleaner, will I see a difference or should I just keep the Harley stage 1. I would really like to change the look but will it be a difference?
A shopper on Mar 26, 2015
BEST ANSWER: I bought a Stage 2 Big Sucker in late fall 2014, and because I live in the Midwest, haven't been able to put too many miles on my Softail Deluxe since. That said, I can say that on a recent ride to Wisconsin, I was very satisfied with the HP, feel, and acceleration in comparison to before. Whether it makes a HUGE difference is debatable, but if you factor in the look--the appearance is unbeatable, it really stands out--it may be worth it to you. I don't regret having shelled out the money for it. Hope this helps.
