Smile oil cooler for B8

Hay friends of the B8,

we you know has the B8 not an oil cooler, we have themselves the trouble made a kit together to set.

The oil cooler with trunk circuit and all attachments are about 320 euro. This sentence consists of:
- Oil coolers with retaining set suitably for the water cooler M3
- 2 hose lines with special press nipple
- small articles such as O-rings and clammy ones fasten the nipple.

The hose lines consist of VA special press nipple and teflon hose with VA coat, temperature to 150°.

Thus the trunk circuit fits like an original trunk circuit, adapted on our conditions.

Also we would like to refer to it; we will sell this kits as racing parts, without calculation and without warranty.

You must be you in the clear, the B8 has no transmitter feeders for the oil level in it.
Also must be waiting after the installation of the oil cooler, until the thermostat leaves the first time oil into the radiator.
Whereupon the oil level must be stopped correctly.

With an oil change one does not need to make this Prozedere any longer, the oil in the radiator not with is discharged.
The first Kit's could be supplied with to at the beginning of of August.
With interest ask pn at me; also to the planning, since the press nipples and oil cooler must be ordered.

This looks very interesting Thomas. Do you know how much this will decrease oil temperatures in normal driving?

if I have the tube sentence ready, I will put a few pictures again.

Oh, I see, additional oil amount approx. 0,5-0,6 litres

280 km vs ~~~~230 is a heavy gain even if the temp is just 10°c in difference,, with the cooler,, is it belt-driven or electric

but 90°c in town is A LOT imo... when i was cruising from Nürburgring to Denmark in middle of May on my Cabrio.. i saw 80-100 °c depends on the speed,, i do not have a oil-cooler but i am saerching for Z3M differental-kappe

it is funny to see like on the BT and you are cruising,, and then decide to have a blast ,, and watch the gauge ,, okey ,, then floor the car ,, how engine oil and diff oil gets higher after a while

First of all, a big applause to Thomas for (once again) contributing significantly to the B8 community

It is great with some data, but the measurements should be made on the same car in order to be valid (or at least the same body style). I have seen great variance between same day / same route engine oil temperature between my Coupe, Touring and Cabrio (s). Why it is this way, I am not sure. It can be that there is a true difference or that the VDO gauges have significant tolerance

With this oil cooler, how much extra oil is left in the system after a normal oil change?

Hello Michael,


the flowers belong not only to me alone, Martin a member in the German forum ALPINA, had started running the first cooler.
Together we have thought up this solution. A Plug in Play solution, without sweat work etc.
The temperatures were also confirmed by other B8 driver.
There will be a good one divergence, however how high is this?

Why does every other ALPINA have an oil cooler? My B6 3.5, B5 and also the B10 BT, everybody has an oil cooler.
The place between oil cooler and front Stabi is the problem, here fits nobody original tube sentence, there is not this place.
Hence, we need the Specially Pressnipples.

In the beginning of the next week the first management sentence will be ready, then put I pictures again.
