Heavy Breather Air Cleaner Kit is rated 4.4 out of 5 by 9.
Rated 5 out of 5 by from waited too long I should have got this from the beginning. Added plenty of power. I'm 5'7 and it didn't cause any problem with leg placement. Just as comfortable as the stock air cleaner. But looks 100 pct better. Though it is a little pricier than other aftermarket brands it's worth it.

Rated 5 out of 5 by from Great function I should have got this from the onset. I add lowers to my Street Glide, so make sure you get the breather with the shorter filter if you have lowers. I had a different filter, switched out and gods honest truth, added 3 hp on the dyna. This winter I am getting a 120st installed and this intake can be used on that engine. Looks super sexy, and you can hear it eating air. Does not get in the way at all. Only bad part is I can't get into my glove box now lol

Rated 2 out of 5 by from Shoddy design So the perfromance of the air cleaner is very good but quite frankly the workmanship is shoddy and below what I would expect from HD. The chrome (aluminum) back plate to the filter is glued on and comes loose and rattles after a while. The adhesive is inadequate to the task and doesn't manage the heat. It is hardly noticeable that there was any adhesive at all. I would expect a lot better on filter that sells for almost $350.

Rated 5 out of 5 by from Heavy Breather Air Cleaner Kit I have been thinking about adding this to my 2015 Road King. I already had the stage1 upgrade, and had the 103 cover on with the round air flow filter. It looked fine, but once I put this beautiful addition on? Whoa! Watch out. It added the look that surpassed my expectations, I am very pleased with the look and feeling. I mean seriously, we love our rides.

Wil this Heavy Breather Air Cleaner kit fit on a 2014 Street Glide w/a 103 and a stock 50 mmthrottle body?

The details talk about a 58 mm throttle body? Just want to make sure it fits before I order it...Thx
Asked by: HDLax
The answer to your question is No. This Heavy Breather Air Cleaner kit will not fit the stock 50mm throttle body. The kit fits 58mm throttle bodies. It is difficult to determine which kit fits which throttle body until you continue using the "Overview Description" tab available on each item. Use the "Overview Description", "Overview", "Guides", and "Fitment" tabs on the website to find the correct fit for your bike. There will be a statement that specifically says 58mm throttle body fitment. If this is not listed, 50mm is understood to be the default as per year and model. Finding the right parts can be a bit tedious with the website but thankfully we are with a brand that supports almost all of its modern era parts and has a vibrant business future.

Do i need to buy a tuner kit to install this?

Asked by: 2013streetglide
Hey 2013streetglide, You do not need to purchase a tuner kit. Your dealer can perform the required recalibration. Hope that helps!
