None of them are self tappers, because that's for steel stud construction and A/C ducting.
All are M6 bolts to weld nuts or chassis tabs.

Happy to report that the heat shield worked like a champ and the tunnel had ZERO heat transfer into it, almost cold to touch in the cooler MRLS weather.

Bump because I'm 99% sure I found the OEM heat shield part number. Hopefully Moti can jump in and confirm.

BP4K-56-441F, a whopping $32 locally or $44 shipped brand new from a Mazda dealer on eBay.



Here's the shield I got from eBay. About 27" long, and the wide end would measure about 22" if flattened out. All the stamped ridges, indents, and edge contours match Moti's pictures as far as I can tell.

Amazon has them for 44 + free shipping. I'll order one and see how it is.

I love this. I pulled my engine yesterday for a rebuild and I was going to order the stuff that you stick on the sheetmetal. This looks much better (and is cheaper)

Looks like you found the right one, afm.
Super light, huh?

Yup, and pleasantly WAY less sharp than similar heat shields on my Volvo

The view under an ND without engine/trans in it shows heat shielding quite similar to Morpheus.

Nice find, Ryan!
This one might be even easier to work with if the dimensions are close enough.
Any idea about part number / cost?
Won't be needing it for my stuff, but if someone is just starting....

I was going to dig around for the PN today but, well, Monday. Will try to look into it tomorrow.

Mazda PN: N247-56-410A or N247-56-410B
Best we can tell the difference between the two part numbers is auto vs. manual and that just changes the hole for the shifter a bit.
List price is $244 and there's only one showing in the country. There will be more eventually, just not yet.

do you leave an air gap between the heat shield and the body? Or do you bolt it directly onto the body? I'm concerned about vibration and rattle noise in my daily driver. I had the OEM heat shields on my NA exhaust downpipe drive me nuts

I was concerned about that too. I used some left over reflectix to create an air gap and some cushioning against rattles. I don't have the motor back in the car yet for results, but it seems to be noise free, and if temps get high enough behind the heat shield to melt it I probably have more problems than a weird smell.

Btw, these threads are fantastic, but if I keep reading them and trying to replicate, I'll never get my car finished to drive it.

I probably shouldn't have spent those reading comprehension tests smoking weed behind our school.
