Well, you're being as much of an ass as you say O-cha is...

Think about it. Blowing some cold air on a massive chunk of metal may slightly cool the outside of said chunk, but the oil temps probably won't be impacted in the slightest. Now if we're talking a massive windstorm blowing cooled air, it might. If this new flow was directed at the cooler, it might make more sense, but even that might not have much impact unless the current setup is severely limited in its design.

Everyone rails at the cost of Dinan cooler, but people seem to forget that it's not just a bigger cooler but it does include a redesigned airflow path. That might be the real issue with our cars, no?

Why does the M-Sport front come with redesigned airflow, too?

well thats my point...I redirected the air flow into the engine bay instead of the front of the engine where the oilfilter assembly blocks most of the air..

Simply put, NO.

I admire your drive to try new things bro, but to be honest, coming from an engineering stand point, what you have done will NOT lower your oil temperatures.

I think calling people ass makes you an ass yourself especaially when you THINK you know so much...I forgot you have a engineering degree in wind flow...You are one funny guy...smoke some more herb in Arizona buddy!!

Yeah your probably right in that sense, but i also did it mainly for asthetic reasons!!! But there is always ways of interjecting your opinion like you did nicely unlike assholes like the post above yours....Any how I value your opinion!!!

To answer your first question, no, that is not the flaw. I hate to say the obvious, but Dinan doesn't know more than BMW does. Oil coolers mounted in the fender-well is GOOD and common practice. What VIP tuning did with thier oil cooler was poor practice, and that was placing it infront of the radiator. Clearly they have no idea what "heat gradients" are and how it applies to this situation.
The stock oil cooler is in an ideal location, I can assure you this.

Your 2nd question about the M-sport bumper and why does it have redesigned air openings.. Well mainly because it needs to look different to be worthy of selling. It wouldnt be anything special if it looked stock. The stock bumper opening is ample for the oil cooler, not to mention the pressure differential created by the wheel itself in the fender-well. A low pressure section is created behind the fender liner and it pulls air through the front lower air dam quite well. I can go into this for a very long time and bore you to death but I wont do that.

Hope that gives SOME insight. If you are an engineer, you should know what I am talking about already.

There is a right way, and a wrong way always, right?

Feel free to PM me with any technical questions you have bro. I will be happy to help.

Good stuff, thank you. Haven't crawled under the car to look at things, but it sounds like you have. Appreciate the insight and I guess the search for a decently priced solution goes on...

Exactly, the air is going in there whether or not you have the silly cut snorkle. No offense bro, but to think that cut piece of plastic is dropping your oil temps 10-15 degrees is laughable.

It might be laughable but my numbers shows something has changed...either the CAI or this silly little snorkel!!!! I am not taking offense to anything...Like i said even if its not the "silly snorkel" asthetically it more appealing in my car!!

Hey, you're not alone here though. When I got my car I drove it for a while then decided to take the front license plate and plate frame off. When I did I noticed it blocks the front center mesh pretty significantly and I "noticed" my car was running cooler and only getting up to around 220 oil temp by the time I made my 20 mile commute to work. I posted a thread stating the change I noticed and wondering if it was because more air was now getting in and everyone pretty much told me (correctly) that it had nothing to do with it. After about a week my temps went back to the normal operating temps and I never really figured out why.

Even now I notice my car runs at a pretty wide range of temps and it doesn't correllate all that well to ambient temps or driving style unless you are really pushing it hard for instance in the twisties where it will always climb well over 250.

I am a little late to the game, but maybe it’s the actual removal of the factory air box that somehow changed the path of air flows in the engine compartment and this somehow lowered your operating temps.

Maybe someone else with the same intake can try out the same mod and see what results they get. You know increase the sample size... :-)
