BMWDoctor N52 Headers

Rickyshucks · 03-20-2019, 05:55 PM

Planning to purchase some BMWDoctor Headers for my 06 325i (stage 3 mani + hass 330i flashed) from a local. Not much online information on them..

Anyone have any thoughts on it?

Go with Roundelwerk. I have them on mine, aI swear they're 100% identical to Active Autowerke's headers right down to the OE style gaskets and O2 sensor bungs.

Can't go wrong. There was a new set on Kijiji recently too.

Dont buy those. Look for ones that have B1 o2 sensor holes
at the merge and not at the cylinder 2 and 5.

Their stock photo online is severely outdated.

They are identical to AA, including proper bung placement.

They're all made in taiwan/china. They probably get them from the same factory that AA does.

I've got them. They work well. Had to beat on one of the engine mounts a little to get them to fit up there however. Great power though

I googled “Roundelwerk N52 Headers” and they came right up. Not sure why you couldn’t find them
