The owner of the bike says it didn't seem to make much of a power difference, but it sounds better. I think you'd probably see more of a performance gain when pairing this mod with an aftermarket exhaust and maybe an ECU flash but I can't say for sure. We might be doing those things next summer.
I have a pack of the UNI’s but I might just try the CB air intake velocity stack only. It will increase air flow but not so drastically where it might not tune well? Or just one Uni in the highest spot on the cover where it fits cleanly?
So why not just remove the airbox door and see if there is a difference? I don't understand the purpose of the little plugs with the filters in them since you already have an air filter before the intake. The water ingestion issue may not be as big of a concern since the air looks to be pulling upwards from the airbox. Look at the design of KTM air boxes and they are typically open along the whole side with the air being drawn in near the top.
Yeah, they might be good for keeping bees from building a nest inside but other than that you're probably right. They aren't filtering the air as well as the air filter does, they just keep larger things from getting in. I suppose you could just drill a lot of small holes in the air box cover for the same effect, but it might sound odd under load.

I did a k@n air filter, full exhaust and ejk and it didn't add up to crap till I hole sawed a 2 1/2 inch hole where the original snorkel was and installed a 2 inch pvc elbow on the top and I gained a ton of low end and a little high end. The motor didn't due that low end chatter when lugging down below 2500 rpm's. This factory snorkel is horrifically small and restrictive. On it's own might not do much but it is a necesary mod to make all the others work to their potential.
@@geraldburmeister9637 I replaced the OEM snorkel with a silicone coupler tapered 2in-3 in. So instead of just a 2 inch hole it's kind of velocity stacked. Definitely sounded better under engine braking. Also put two 1 inch uni filters on the air filter box door. Just did the EVAP and pair valve delete a couple days. I got the 550 ECU stage 1 with a full Yoshi. It had slight deceleration popping until I did the pair valve delete.
Would love to see a before / after performance comparison. Thanks! 🙌

@@EndlessMoneyPits Word - thanks. Still enjoying my 2015 CB500X with Rally Raid kit, but I love the CR-F! Keep up the great content 🍻
Good set of bikes right there! Thanks, man.
You don't need the plugs at all, there is a filter in there ... Just make holes and finished.

You probably don't need to install as many Uni filters as I did. 3 or 4 is probably sufficient. Even just one or two should help some
No not painters frog tape this material is a membrane air transferable but keeps water out cheers
Interesting, thanks for the tip!

Nice
I would just leave the blue foam inserts out.. they just restrict the air anyways... Gotta go through the air filter anyways right?

But... what do you do when that clogs up? Pop the lid off and blow out the lid?
Yeah, that should work. These aren't very fine filters and they aren't oiled.
How often are you gonna submerge the air box in water?
Never.
Whatever you do, make sure you don’t tell us what kind of improvement it made 🤦🏻♂️

Frog tape is much better it’s waterproof cut the desired hole size stick it on. Waterproof washable to watch shonky production for the mod
The painters tape kind?
It's Frogskinz not tape
Thank you for clearing that up. I had never heard of frogzskin air vents. Looks like they would work better than the vents I used.
Yeah, the upper 3 positions look useless anyway
Bro it's fuel injected and computer programmed, I don't think that's going to help much.

Seems like a pointless mod to me if it's not going to give you any gains and now your prone to flood your motor if you hit a body of water.
No gains?
I've seen several posts of Air box mods and they all say " no noticeable gains" except the ones that also install a new exhaust and flash the ECU
@Mobstar76 to be fair, it's a 300cc engine. "Noticeable" gains will be very difficult to come by.
