Direct fit oil cooler upgrade

Billit335 · 07-22-2015, 02:31 AM

I've been scouring the interbwebz for a direct fit for those of us with a factory oil cooler. It seems the E90 M3 tranny cooler from CSF CSF -8042 is the part number oem oil cooler.

The M3 guys are using it to cool their trannies but E90 guys can us it to cool our motors.

This is their site, I've also installed an all aluminum radiator, outstanding quality !!

Anybody try this cooler ? Thoughts ?

davidwarren · 07-22-2015, 01:03 PM

if you are considering replacing your OEM cooler with that, I doubt it would provide any significant improvements.

Cloud9blue · 07-22-2015, 03:33 PM

Only 30% increase in efficency over the tiny OEM setup. Definitely not big enough to make any noticeable difference.

Most aftermarket kits offer 200-400% increase, just FYI.

I wish they would make a mirror image one that bolts up to the drivers side. Then we could run a dual oil cooler setup.

+1 but I think in that case just upgrade to the one the 335is comes with on the drivers side

Hmmm is there pricing anywhere? I'm on mobile and don't see any. This would work well for my oil cooler retrofit.

Billit335 · 07-22-2015, 08:43 PM

Price is 599, it's the thermal rejection that makes it so awesome. It's what's inside that counts, not just surface area.

Big things come in small packages, even this engine is only 182 cubic inches but is a beast.

It's track proven at Thunderhill Run, a 25 hour balls out race.

Very interesting. Someone needs to buy this and give it a shot.

Yeah, but it was being used as it was designed there- a transmission cooler for an m3.

Billit335 · 07-22-2015, 09:29 PM

I'll bit the bullet...

The stock one was designed to be both an oil cooler and trans cooler. It stands to reason that an upgraded direct fit unit would work equally well in either application.

Billit335 · 07-23-2015, 09:56 PM

It's race proven in an M3, so I'd be inclined to give it a shot. M3 guys are buying these up like crazy.

I agree. I'm just saying that I doubt it would provide very much of an upgrade. I would love to be proven wrong, however.

It is VERY easy to build a custom oil cooler if you are halfway decent with a wrench.

Buy an eBay OFH adapter
AN10 lines
20-30 Row AN10 Core (no-names perform just as well as brand name in my experience)
Some additional hardware for mounting (may have to get creative)

Voila, a $200-300 oil cooler that outperforms the $1300 Dinan unit
