STM Tuned Inc.


More info below

The STM Engine Oil Cooler Kit for 6-bolt DSM is designed around your needs as you can cut the length of line to your specific liking for a perfectly custom set-up. Utilizing the well known and trusted B&M Coolers, combined with high quality Vibrant braided nylon line and black aluminum fittings, this kit has everything you'll need to get this done the way you want.

Designed to bolt up to the factory 1990 DSM oil filter housing. If you have an air cooled housing in your DSM, it will work for you. It will take a little bit of DSM DIY work, but this setup works perfectly and we have sold a ton of them with great results!

*Currently Unavailable*
The 70273 B&M cooler was discontinued in February 2023 and we finally ran out of stock in June 2023. We will be working on redesigning all the STM oil cooler kits. Stay Tuned!
