Part Number help needed please. 2001.5 intake manifold

[MarkB]

This is excelent info. I'll take some similar pictures of the early type manifold so we can compare.

As far as I can see, this is only relevent to the B5 S4, would this thread be better in there?

I think it's worthy of linking from the B5 S4: Modifications sticky (so I've done it). Top work

Thanks Mark mate, yep your right the S4 B5 forum would be better

just to clarify to fit this manifold in place of the early S4 one you need to;
- move the N249 connection to the connector on the top in the pics,
- cut off and tap both fat connectors,
- block one with a threaded plug
- convert the second to 1/2" barb for the brake vacuum hose
- re-locate the EGT sensor modules

I think that's it, I haven't done it yet, but will post a how to when I have.

I'll move it over then

One thing I'll add when I do mine is... I plan to replace my spider hose at the same time with the later version ( minus the f-pipe) so this might connect directly to the BC manifold.

The RS4 / 2001.5 spider needs the "suction jet pump" assembly, the u shaped arrangement of valves and pipework........



9 and 10 connect to the fat connectors I chopped off of the back of the BC mani,
7 to the brake servo and 3 to the spider.

So you would need to build this as well from audi part numbers, I looked at it, but unless you can get one second hand it is prohibitively expensive. If you can get it you will have effectively built a late allroad mani and pipework setup. There are a couple of other small hose differences as well including the one to the N75.

[MarkB]

Ah, more than I thought. I'll be looking closer at your plan then

I tried to find straight 3/8"BSP to 1/2" barbs but no luck.

How about THESE?

yep look great, should work well. (Mark! )
