If this is it, it can be found at Geno's Garage.
DIESEL TURBO LIFE SAVER - 1 - 250 MINUTES ('06-'07 DODGE) $264.99
I have seen other types and I thought there was one offered from the DTR Store that would work and they were less costly to the tune of about $90.

Edge Juice with Attitude. IMO though, get one that works on temperature and not time...you are trying to reach a shut-down temperature, not time. So, you will either be idling too long or not long enough...

LOL, the old "turbo timers", if I were you I would save my money, with synthetic oil you do not need to worry about "oil coking" in modern turbo applications.
MYTH #7
You have to let a turbo-diesel idle for two minutes before you shut it off.
FACT
This is a current myth that has a basis of fact stemming from many years ago. It also has a kernel of truth regarding today’s turbocharged gasoline engines that operate at higher peak exhaust temperatures than turbo-diesels. In the early days of turbochargers, the turbo shaft was supported by a babbitt bearing that could seize, or even melt, if the engine was shut off immediately after sustained boost conditions where the turbocharger would “heat soak”. A two minute cool down at idle allowed the turbocharger to dissipate any remaining spinning inertia, and the oil circulation cooled the bearing and prevented oil “coking” in the bearing area. Turbochargers haven’t used babbitt bearings for over 30 years, and today’s oils resist coking. Synthetic oils won’t coke, period. With a turbocharged gas engine, it’s still good insurance to let the engine idle for 30 seconds to a minute to allow the turbo or turbos to dissipate any inertia and to cool the bearing area to prevent oil coking, especially if the engine has been worked hard just prior to shut-down. Of course, using quality synthetic oil eliminates this potential coking problem.
Today’s turbo-diesels are a different story. There is really no reason to “cool down” a turbo-diesel these days, but you won’t hurt anything by doing it either. You can still find people who swear you have to do it, but the myth is fading. Maybe they just like to sit and listen to the radio.

I'm interested in a turbo timer as well... I have seen lots of import performance turbo timers, wondering how these would work in our application, like these:

I've been running twin turbo street cars for over 20 years and with synthetic oil and modern turbos you will not need a turbo timer, its a waste of money.
But, its your cash.
BTW, the bearings in your turbo are not seeing 1250 degrees.

Bottom line is, most of the average joe's who buy a diesel don't read up on them on the internet, and probably don't let them cooldown. I know plenty of guys with 300k+ miles on their trucks and they've never let it cool down since they owned it and haven't had a problem. I think people worry about this too much. With that said, I usually wait 1 minute before turning mine off.

Spend the money on something else...

I would save the money for something more worthwhile.
