Karb Race airbox vs regular airbox

[EthanolTurbo]

Does anyone know what the true differences between a regular style CSL airbox and Karb's Race box are? I know the race box has the integrated snorkel, but are there any downsides? Less noise, worse fitment, power etc? Thanks in advance for anyone that has experience with these.

Also curious if the race box snorkel would fit the CSL style and vice versa.

Main difference is weight. Race is lighter than Karb snorkel and much lighter than the CSL control flap unit. The main unfiltered section is the same on both Karb airboxes. If you are using a CSL bumper and want an easy connection/route to the airbox, you want the standard airbox with snorkel. If you are using the stock ducting, the Race is fine. All essentially sound the same and make the same power.

Do you know what the weight difference is? There seems to be about the same amount of carbon in the race unfiltered section as in the regular unfiltered + karb snorkel. Only thing I can think that would make a difference is the lack of aluminum flange on the race version.

It's probably a small difference, but there is the flange and maybe added carbon layers with adhesive to make the more complex piece.

Now I'm curious. If anyone on here has the race version (or gets it in the future), it'd be interesting to see how much the unfiltered section weighs. I can weigh my regular unfiltered section + karb snorkel too.
