Dinan High Performance Heat Exchanger - 2019-2025 BMW 330i/M340i/430i/M440i
The OE thermal management system for the B4x/B58 G-chassis BMW and Toyota GR Supra offers an improved formula from prior generations. With a setup where engine coolant is also re-routed through the heat exchanger, the system effectively assists in overall engine cooling as well as charge cooling. However, like its predecessors, it has room for improvement as it can be overwhelmed when the system is taxed aggressively or as power levels are increased. Once overburdened, this results in the undesirable outcome of power being diminished. Avoidance of this unwelcome scenario can be attained though with a Dinan heat exchanger that improves the overall thermal management system so everything runs cooler and more efficiently while being budget friendly.
Features:
- Average of 8.7? C reduction in charge air temps with a maximum reduction of nearly 12? C over 30 successive WOT pulls
- General improvement to the efficiency of the thermal management system, inclusive of engine cooling
- 45mm thick Dinan core vs. 26.75mm thick stock cooler core
- 68% more cooling surface area and volume than stock
- Reduces the tendency to heat soak / go in to limp mode
- Durable bar and plate design that is less susceptible to damage from road debris
- Pressure tested, 100% TIG welded, Aluminum construction
- Direct fit replacement with no modifications required

Not a happy customer
My Aussie ate the chew stick within 5min. Disappointed it didn't last longer. Won't buy again :(

Massive treats, no tummy rumbles, but a little pricey
I'm always a little tentative when ordering dog treats online, because you don't always know in advance where they're sourced from, or what weird processing might be done to them, or what weird additives might be thrown in. These are sourced in Mexico, and they seem to be straightforward in terms of ingredients. Phew!
The smell of these is not the best, but if you've fed your dog collagen treats before, I'm sure you know what you're getting into with that. The dogs loved them, for sure. These treats are MASSIVE, so if you have a small or medium sized dog, you might want to cut them into two or more pieces. For my 60ish pound dogs, they were very large but manageable, and the way their eyes lit up when I presented it to them, it was like Christmas. LOL
The only reason I'm docking a star is because these are not long-term chews, at least for my dogs. Yak chews will generally last for a couple of hours for them, which I break up over several days by taking the treat away after a while and giving it back to them the next day. These chews were gone within about 5-10 minutes. (Five minutes for my spazzy dog who acts like treats will disappear if they're not hoovered it into her gullet at breakneck speed, and ten minutes for the other who likes to taste his food on the way down.) At almost $6 a pop, these are pretty expensive for 5-10 minutes of enjoyment, so this isn't going to be a treat I buy for them on the regular.
There were no issues with tummy rumbles or nausea or diarrhea afterward, so that's good. And I like getting a little more collagen in these kids because they're both getting up there in age, so their hips and joints can use a little extra love. If you've got the extra money to spring for these, or if your dog paces him- or herself reasonably with dog treats, this could be a good choice for you.

My non-chewer loves these
He is not into chewing, tried many different ones.
But he’ll chomp down on theses, and they seem to be all good stuff

Dog loves them, no rawhide!
My dog is obsessed with these! We have a 70 pound pit mix who is a power chewer and these rolls last forever. He goes crazy for the peanut butter taste and it takes him a couple of days to really destroy one entirely. They are very effective for keeping him busy as the size is massive. I like giving him something so large because he then sets his mind to it for a long time. I like that they have a lot of collagen in them, I can't say I've noticed that his coat is a great deal shinier but it can't hurt! I also like that these are rawhide free. I would say these are a good value as they keep him busy for a good amount of time.

These are great my dog loved it
Well, I can say one thing I have shepherd. Wolf hybrids, and they are very particular about the stuff they eat. I can give them raw meat, and if it's old, they don't want it, so they're pretty finicky, I hooked them up with these. And they didn't hesitate to go at them. So I wait, I fed half, and then waited a couple of days, they had no negative response to it. That I'm aware of and so I gave him the other one and split it between them, and they don't stop until they're gone. So they pretty much sold themselves for me. If mine My dogs will eat em.They must be okay worth the money in my book.Made my babies happy should get some for yours my dogs are like super chooers.Okay, they have jaws that break bone.So to try to say that these are not good for heavy chewers, I i can't agree with that.Although they won't last very long with heavy chewers, they do great.The dogs love them we only smell was the smell of the product.Kind of a food smell to it.And as soon as I opened the package, the dogs had me surrounded like the sue did old custard, and they weren't letting me go until I shared straight up the male's a hundred plus pounds.And he's eyeballing me like, i'm gonna be lunch.If I don't give him a share, it was funny as hell a great product i think one of the things is the peanut butter.That's in them.My dogs love their peanut butter now.These are almost a foot long each stick, and they're about an inch and a half in diameter.Now they would last for a pretty good time for a normal chew type.DogRottweiler's pit bull saint bernard's high bread.Shepherds, et cetera, anything with a two thousand pound byte is going to tear these things up and have a great time.Doing itThey won't last as long as the dainty chewers and the the comfort chewers, but they'll do the job
