Looks like it just came out. Not sure if anybody has had a chance to test it out yet. Maybe they had some local vehicles using it before they put it into production. Grimmspeed makes great stuff and seeing that they are in Minnesota they probably designed it to eliminate any chance of the milky build up seen in other AOS systems.

Keeping an eye on this for more testing, looks interesting.

$300 is a little steep IMHO. However I will wait for some feedback as well.

I just noticed this today as well while looking at their BCS. I'm VERY interested in this as it seems to have been developed in response to issues some other AOSes are having. I'm curious if it is actually effective considering where it is installed but we'll see. Grimmspeed products are usually top notch and the third port looks interesting and much easier to maintain than say the Crawford unit. So as long as it works, it seems to offer a lot of advantages.

Looks top notch to me. I've been debating on either a couple Perrin catch cans or the Crawford. This looks like a winner to me. Cheaper (especially with my military discount), looks cool, and I like their design. I'll be getting one hopefully in a few weeks.

Didn't know Grimmspeed had a military discount. Must investigate further.
