Does anyone know if VK Motorwerks is still selling parts. There web page is active but the phone and email are no longer valid. I am looking for an oil cooler alternative to the Dinan one and theirs looked viable.

Thanks

If you can't get a hold of VK, we have a really nice solution available for less than 1/2 the cost of Dinan!

I wouldn't buy VK OC if I had to buy again. Go for ar design.

switch the vk cooler core for one of Setrab and it is perfect

Sorry. I was tired and in a hurry. I wouldn't buy VK OC. I was dissapointed a bit with it. Go for ar design.

are you guys talking about upgrade oil cooler, or a retrofit kit? i am still looking for an affordable retrofit kit as i have no oil cooler.

I personally know two people who had the VK Motorwerks oil cooler and where said oil cooler fractured after some spirited driving. I won't say this happens to all of these, but it seems a clear tendency.

This problem caused by the fact that in order to mount the core that VK Motorwerks uses, such core has to be cut on the edges (otherwise it doesn't fit in the mounting position). That cutting destabilizes the core because the seams of it aren't perfect any more and, if you put some stress on them (i.e. spirited driving, hot oil temps, expanding the core), are prone to fracturing which causes oil leaking out.

You can remedy that by using another core such as Setrab which does not need to be cut and will therefore not fracture (as marcel_b has done), or you can go with the AR design oil cooler in the first place and not have these problems.

And I'm not impressed with it's performance.

as long as you are not increasing the airflow on the oilcooler you can only limited benefit from it. Mr.5 added a M3 replica bumper which has much bigger airvents and with that much more airflow on the bigger oilcooler increasing it's cooling performance. The M3 have no foglights for a reason!
I am installing the 335is airvent and ducts for the same reason. A guy I know already did this and has very good results even with the standard oilcooler. (drop of 15 degrees Celcius in oil temps) Something to consider....
