This is a common failure on 6.7L Powerstrokes...

As Truck Source Diesel & Off-Road shows, the stock rubber intercooler tube bursts leaving you stranded. Do the smart thing and replace that weak point with the S&B Intercooler Pipe featuring a robust 5-ply aramid reinforced silicone hose, paired with polished aluminum pipe, and heavy-duty stainless steel T-bolt clamps for bulletproof reliability.

Plus, the S&B pipe has a larger diameter improving airflow to your engine, translating to better performance. 💪

Ready to upgrade to lifetime durability and better performance?

Well well well… what could this be for?

We’ll give you a hint.
It used to be red.

Maxed out the dyno with the second rip on the new billet motor with the exact same tune from UCC 🔥🔥

Got Sterling Diesel & Off-Road billet motor in and the truck ready to get back on the streets.. made a quick pull to break it in.

May be time to upgrade the dyno…

(This is not an engine failure… just a rowdy dyno pull)

We were excited to see Truck Source Diesel & Off-Road bring “Blackbird” out to this year’s Ultimate Callout Challenge / ODR Race!

This absolute unit is powered by our complete Ordnance fuel system and S&S firmware on a Motec Systems USA ECU, delivering the fuel and control needed for one serious combination.
