K&N air filter fitment question - nikolus_imp - 09-10-2018
Hi there,
I just bought a K&N air filter and I wonder if I received the right part…
It is supposed to be the HA-1301 but as you can see the inside diameter is smaller than stock:

Is it the right one and if so what did you do to be able to put the snorkel back properly (or the TSR air funnel) ?
Thanks

Part # matches up correctly. ID difference looks substantial.
If I were you- and you continue to want to use it, I would take an exacto knife and cut the hole larger to match.
That being said- although I never tested the K&N on our bike, I don't think the stock filter is limiting anything. I could be wrong.
The TSR plate I did dyno on an otherwise stock bike +staintune muffler.
In that configuration the TSR plate made a tiny bit of power at the highest RPM, but it also went lean enough down low that I would not personally run it without adding fuel.

I'm not sure what the deal is, but I bought one and it was exactly like yours. I spent hours trying to get it to fit, but never could get it to go in far enough to get the snorkel on.
Unfortunately, mine had sat on a shelf for a year before I tried it, so I wasn't able to return it. Ended up chucking it
Mine was also labeled as an HA-1301, which is supposed to be the correct part for the CB1100.

Yup. If it ain't broke don’t fix it.

If anyone else has one lying around that they are going to chuck- I'll give you a few bucks for it so I can try to cut it, make it fit, and dyno test it VS the stock filter.

It's weird it needs to be chucked since it's supposed to be a direct fit (asked K&N and got no answer yet)… anyone else before I return it?

I'm the second owner of my CB. When I went to change the air filter and discovered the previous owner had installed a K&N, it soon found itself at the bottom of my trash bin.

Dang, well HA-1301 is the right spec filter, right from the K&N web site. K&N screwed up somewhere. I've used K&N on ALL my vehicles throughout the years, never had a problem, always fit, love that they are cleanable/re-usable! Will soon get one to try on my newly-purchased 2013...
