They've been out of stock for a few years now.... I wouldn't count on them becoming available.

I grabbed a NOS brass one on ebay a while back. And I'd been keeping my eyes open for one for a bit too. Few and far between, but they do pop up occasionally.

Would like to see NPD bring that one back. They soldered the on tube back to the body of the core which should have eliminated most of the failures on the replacement units. This was a common issue on the replacements as the offset in the nipped added another stress point to that piece and they typically failed where it was soldered to the core. Soldering it to the body at the bend would strengthen that and all but eliminate the failure.

They were available a couple months ago. I almost ordered one when they first released. I think it's reasonably priced and they soldered a support to one of the tubes which was a weak spot on the original design.

If you can afford to wait, might be worth holding off picking one up.

About ten years ago I replaced my heater core( ford engineers suck ass) I used one from LMR with the reducer for the inlet hose.
No problems with it and I do daily drive the out of it. (316,000miles now) So feel comfortable to use the same one I did.

yes you can see that in that pic looks more secure. I hope they restock it i will buy 2 ...or maybe just mod that Spectra Premium the same as the solder on the brass one...

I got one from them a few months ago. Can't comment on the longevity just yet as I don't have many miles on it, but it seems well made. Clean solder joints. I think it's the only copper / brass replacement out there. I'd shoot em an email. They might have ETA.

Just got both delivered to me today, and it looks pretty decent. Nice solder points, made in Mexico sticker on it lol I even got charged an extra 115.00 tariff tax, before UPS would drop it off , for a grand total of 339.88 Canadian or 247.80 US dollars for 2 heater cores in the same box shipped to me check out the pics. Next will be heatercore install time.

Yeah, couple of days ago. Unboxed and they look great. Boxed them back up and put on the shelf for down the road.
