They are completely corrosion-free, even after spending their first two years submerged in the wet, salty roads of Maryland.
About to do that.
It is over 100°F here, so it should be a good test.

Just did this mod today. I went for a short 4-5mile drive and recored the temps. I then did the same drive after the mod same speeds and temp 30 mph and 71 deg. The results wrere as follows using a IR thermometer on the outside of the cooler.
Before: DS-169 PS-155
After : DS-147 PS-140
15-22 deg drop in cooler temp is not bad for free.

I'll snap his neck.
C Ya L8r - That's good to know - thanks! Anybody have any problems with road debris hitting the coolers, etc after doing this mod? Just wondering why Mazda didn't have the openings bigger in the first place.
Jeff - any word on your "move where the food is - nothing grows here" desert test?
Thanks for doing the research on this!

I knew my guesstimation was about right, and I was not imagining things..
Yes, even for this slight reduction in temps it has to be worth it.
I can not though agree on the other mod which virtually exposes the oil cooler by 85%..can't be good for rocks, stones and road/wheel water and mud.

wow nice results from cyal8r, was waiting to see some hard data, anywhere near 20deg reduction in temp is AWESOME. your engine will be happy.
MazdaManiac - all the lines i normally run into are brass-ish but they seem to have a coating on them cause it doesnt look like any immediately recognizable metal. I'll start looking to see if i can find a pattern.

Now we need someone to measure oil temps before and after. My test proves tihis mod mkes the coolers more efficent. But thats not to say overall oil temps will drop 15-20. Also 30mph is pretty slow but I wanted a route where I wouldn't have traffic variables.

the fact it did anything at slow speeds is pretty good considering such a lack of air velocity.
as for why mazda didnt do it... probably so animals couldnt hop in.

Cool mod!! Was wondering if any of you knew the actual part number for those OEM splash shields. A curb reached out and grab one of mine the other day and I need to replace it, and plan on doing this mod while I have the wheels off anyways. Searching for "front wheel well inner vented splash guards" (or any combination of those words) doesnt seem to help. Or I just am using the wrong part names. Thanks in advance

I did it, but won't be testing the temps. It was worth it to see the oil cooler lines. The drivers side had some rust, but the passenger side was clean. I'm going to buy some spray grease from Amsoil and coat those and a few other areas under the car. Once before and after winter should help with long term corrosion.

i was just thinking if you cut out most of the backing and if u put in some wire mesh to cover the hole that should help with keeping road debris out of the coolers, wouldnt that work and alow alot more air flow

But hey, I have been thinking perhaps a quick replacement type plastic shield, one Open mesh type for Summer and the original slit vents for Winter?

I'll have to do this soon.
If I do this in the next few weeks, I'll make sure to monitor the actual oil temperature and post my findings.
