I believe this is the AA belt for C38 blowers with 85mm pulleys. (Prima and Prima Plus)

Does anyone happen to know the part numbers for the two idler pulleys on the VF kit? Apparently one is smaller than the other. Any clarification on this would be greatly appreciated.

I'm so glad I found this thread. recently bought a AA supercharged M3 and this will be a lot of help. Thanks OP.

I hope this is a worth-while contribution. I've been looking to replace the mangled air filter thats on the turbine. I did some research and it looks like I found a K&N and Green filter that fit. I listed both because I'm under the understanding that AA used to use K&N and now use Green and we're trying to keep this limited to brands that came with the kits. I'm not 100% on these but someone could chime in if you know for sure.

K&N: RU-3130 ~$36 on amazon

Green: 7124 ~$35 on amazon

Does anyone know of a message thread like this (or other web page) for the e36 M3 AA kits?

The K&N: RU-3130 does NOT fit the HKS blower.

Going forward, I am wondering if anybody know what other kit this System would be most similar to for purposes of maintenance? I believe it's a Vortech blower (non-intercooled, 4.5psi, shared oil). Any idea when a rebuild may be necessary, or if there is any other component that can/should be serviced?

Did you ever get an answer for this?

What is the recommended spark plugs for the AA Rotrex setup? I searched the thread and cant find where its mentioned. Gap would be awesome to know as well.
