I just got a 2026 Heritage. I bought the HD tuner and a Rinehart slip on. I am looking to do the High Flow Air Cleaner to complete the Stage One... Harley doesn't appear to sell one for this bike.. I am looking at the Arlen Ness big sucker. What are most using with the 2025/6 bikes ??? Thanks in advance for your thoughts...
At first glance, it does not appear that Harley has updated their website to include most parts for '26 Heritages yet. (I didn't have that problem since I bought my '25 in early fall.)
In my personal experience, the Big Suckers would flow more than enough air for a stage 1or 2, but the build and material quality was crap. Look into the products at DK Custom. They are sponsors here and have great customer service as well. I found them to be much better made than AN stuff.
I'm running the S&S stinger on my FXBBS and my FXDL/I which they claim has
55% more air flow. I like the retro look. Might not be the style you are looking for.

The air cleaners that work on the 2025 will work on the 2026, there is no change in the throttle body or mounting. Anything from 2024 back will not fit, except the some of the touring stuff from 23 1/2 & 24. If you only change the muffler, you really don't have to use the tuner, but the free flowing air cleaner will need it from what I have been told.
I'm personally not a fan of big clunky or busy looking A/C's. I've ran AN Big Suckers for many years with zero issues. Plenty of cover styles to tickle your fancy and priced reasonably, unlike most these days. Pro tip, always match the finish of your air cleaner to your exhaust. Example, black exhaust, black air cleaner, chrome exhaust, chrome air cleaner, stainless exhaust, machined finish. You know, for asthetics.

The reason HD doesn't show a hi flow for your bike yet is they haven't released an EPA approved map. Supposed to be available by April, and once released, they will also show fitment- I do know the air cleaner from a 25/26 CVOST, FXLRST, SE Round AC, SE Wedge, SE Heavy Breather Extreme, and SE Vortex will all bolt up.
