The stock filters don't fit the RB aluminum assembly. You need the K&N E2700 which is smaller OD. It also will fit the stock filter assembly. It looks small compared to the stock filter element.
The K&N probably flows more air than the RB foam one, especially when dirty.

I understand your point but this air cleaner came with my rb 600 holly street port kit . I would imagine they would change the element for performance in they're performance kit . I have brought this to rb attention in a phone conversation and became a dead issue very quickly . Bottom line is that the air cleaner sucks for performance but I own and like a lot of rb quality parts and respect them in the rotary world . And I also agree with Jeff about the k&n .

Way back in the day, my friend had a green rotary truck that he rebuilt and mild streetported the original 3B engine, going from its stock 74 spec ports of 50 degree closing out to about 55 degrees, so not as extreme as an actual RB streetport template, as this was still intended to be used as a truck and he wanted to retain at least some low end torque.
Back then, RB still sold the 550 CFM carb for streetports, so that's what he got. He kept the heavy 30 pound REPU 9 bolt flywheel which seemed to do ok but he did occasionally burn the clutch when he was messing around, lol.
His points ignition was swapped out for a 1980 version which we know today is clunky and lame due to having to mount the ignitors with their heat sink control housing somewhere on the firewall. Oh well, he was a noob.
His exhaust was an attempt at a long primary but executed poorly and didn't flow much at really high RPM. Again, noob.
The point I'm eventually getting to is about the foam air filter in the RB aluminum housing. He drove this thing everywhere and would need to periodically adjust the idle and accel pump on the Holley due to changes in seasons. He also included spark plug changes in his "tune ups" because his setup would foul them after a number of miles for some reason.
It turns out the foam filter would load up with dust/dirt/road sand etc and he discovered the engine would run a lot better after a simple cleaning of the filter. Likewise it would run better after an oil change. He liked to use 20w50 which as we know these days is pretty thick and power robbing.
This green REPU is largely responsible for getting me into rotaries despite his noobish shortcomings. Thus I learned a lot and set my REPU up in a way as to correct all the noob mistakes he made. I won't bore anyone in this thread any further than I already have with the setup I decided to go with, but I will say I went with a hogged out boost prepped Nikki instead of a Holley, which will be run NA for now, with an RB aluminum filter assembly and a K&N filter because I just don't see how the foam one will be of any benefit. It's like a "been there, done that" sort of thing at this point. Plus it's really oily and gross to deal with.

Has anyone tested the RB ali filter housing against, well anything. E.g. remote filter, factory housing. I like the look of it just the opening from top half to lower half looks a bit small/restrictive?
