Hello All,

I'd like to gauge the level of interest in a plenum to be used in a CIS to EFI conversion.

In such a conversion, the stock CIS airbox housing has to be trimmed or cut down for use. Yes, you can retain the housing and use the stock air filter. But if you otherwise want to use a different setup, I'm trying to make this plenum out of carbon fiber.

My approach is to cut down a stock housing and then mold a complete unit out of carbon fiber.

Any input or ideas to improve over the stock design?

I'll post some pics later.

For reference, the part number is 911 110 106 13. There seems to be 4 different part numbers, perhaps for different regions.

I will be converting my CIS 83 to EFI during the next year. Id be interested.
