Default Iron 883 round filter mod

Hi
I started to wonder if any of you modded original air filter cover in iron to let more air inside
I recently bought new k&n insert an I'm thinking if the round box isn't the weak point of intake?
Maybe drill some holes or cut some back plastic

I don't want to install other filter, I like the look of this round cover

Some people have done some nice mods to the stock airbox/hamcan cover. Do a search on this forum you should find some examples. With an 883, I wouldn't worry too much.

On both the 883 & 1200 Iron, I used the V&H "Nekkie" Air filter kit, easy to install, nice well made product, I also used V&H "slip-ons" and finally the FP3. I used the fac round cover as I also like the "look". It flow plenty of clean fresh air, and works just like it was made for it. This "Stage One" to me is a must for these bike, Regards "Big E"

Did you modified in any way the original airbox or the construction is good enough to use the high flow filter inside in your opinion ?

If all you purchased was a filter then yes you have a bit of a problem. If you look at the SE airfilter upgrade, it comes with a new back plate to open up the airflow.

The limiting factor is the area around the butterfly in the throttle body.

On both a 2016 883 & 2018 1200 "Iron", I used the V&H "Nekkie" kit. Was about $140, I Installed everything that came in it, You can leave at that OR you can also put the Factory cover back on, fits just fine, with the square "Opening it has on the bottom and it sticks out about 1/2 inch from the V&H plate, it gives plenty of air flow while making a tight seal against the filter element. Also really helps against water. I also added V&H "slip-ons" & the FP3 on both bikes, Total cost wuzz about 1000 ( with black pipes) and little over a hour of time. Im on a working mans budget, but this is what my bikes needed for me to enjoy them, Sound & Power Is perfect for me, Regards "Big E"

Some folks cut all of the flat part out of the back plate, leaving only what is needed for the filter seat, the bolts to the throttle body and the breather bolts. This will give you the most air. Other drill a bunch of large holes into the back plate, Anything you do to open it up is a good thing.

Also, remember to install an External Breather System (EBS), otherwise you are still feeding hot, oily, oxygen depleted air into your combustion chambers...which is a performance robber.

If you are unfamiliar with an EBS, here is a LINK with some info on them.

Couple of pics from the link above-

I drilled 9 half inch holes around the backing plate right around the diameter where the metal air cleaner fits. I noticed a improvement right away. Im still using the oem filter at the moment, but will replace it with a K&N soon.
