1 What's the Bosch part number for the MAF without the plastic tunnel?

Euro Car Parts are taking the p*** at £200 for the tunnel version.

2 Would you ever buy a non-Bosch copy?

I remember somebody saying on rr.net that one from a Saab of some description fitted and worked. No idea on the part number or how well it worked though.

Can't tell you the part number, but if needed, you should get a genuine Bosch. Gems does not seem
to mind pattern parts, but Thor will generally run like crap with a copy.
Be aware that there are a LOT of counterfeit Chinese Bosch parts floating around.
A genuine part will have a holographic sticker on the box with a unique code number.
Take that code number to the Bosch parts checker.

Enter the code, and see if you got a good one! Just having the sticker is not enough.......
They are counterfeiting those as well!
Yes, they are indeed stupid expensive!
Happy hunting.

Thanks everyone. The hologram thing is a great tip, but I normally buy from reputable outlets. Your comments have put me off eBay!

Bosch F 00C 2G2 029

Rare as rocking horse poop and obscenely expensive.
