Looking to add some airflow to your 2007.5-2017 stock or modified Cummins diesel? Our "Max-Flow" Air Horn gets rid of the restrictive factory air horn and opens up 100%+ more flow to your engine (flows similar to a Banks Monster Ram). Whether you are just trying to make your stock truck run better or free up much-needed flow with an upgraded truck this is the upgrade for you. We made some great changes to the horn including adding an Us-Made Viton Oring instead of a gasket so you no longer have to try to line up the gasket and the bolts when installing the new air horn which can be a cuss-worthy endeavor, as well as the features below. We offer the DIH4 heater as an option pre-installed Features of the Horn
- Stock Location fitment for plug-and-play install
- Much less restrictive, boost pressure is increased without adding WGDC
- Outflows the stock intake by over 100%
- 4" Inlet for Max-Flow Boost pipes
- 4 1/8" NPT ports for optimal use of Methanol or NOS
- Integrated Viton Gasket to replace the stock gasket (eliminates having to line up the gasket)

VTT Billet Aluminum Valve Cover – Cummins 6.7L (2007–2020)
Performance. Reliability. Function.
VTT is proud to introduce our Billet Valve Cover for 2007–2020 6.7L Cummins engines. Designed for truck owners who want to eliminate the failure-prone factory crankcase filter and plastic valve cover, this high-performance replacement delivers strength, style, and superior crankcase ventilation.
The factory setup is known to crack, leak, and allow excessive crankcase pressure. Our billet aluminum valve cover fixes those issues while cleaning up your engine bay and providing modular ventilation options. You can route a hose under the truck for vent-to-atmosphere operation or pair it with our VTT Billet Catch Can for maximum filtration and oil control.
Available in Red, Black, Blue, or Clear anodized finishes to complement any engine bay.

VTT 6.7 Cummins “GC” Turbocharger Upgrade
Ready to take your 6.7 Cummins to the next level without dealing with core charges, long lead times, or restrictive factory housings? VTT has you covered with our 100% new casting GC turbocharger upgrade.
We retained the best aspects of the factory Cummins turbo design while eliminating key limitations—such as outdated 12-blade turbine wheels, restrictive turbine housings, and cast compressor wheels. In their place, we’ve implemented modern aero advancements, including a billet cobalt VGT nozzle for increased durability and long service life.
Many assume the compressor wheel is the primary factor in power production. While it plays a role, the turbine wheel is the true driver of turbocharger flow and performance—including blade count, aero design, and efficiency.
By replacing the outdated 12-blade turbine with an advanced 9-blade Inconel turbine featuring modern aero and weight-reduction cutouts, the GC turbo delivers:
- Stock-like spool characteristics
- Significantly increased flow capacity
- Up to 700 WHP capability with proper supporting mods
We then take it further with proprietary VTT design enhancements and OE-quality castings, resulting in a true drop-in turbocharger capable of serious performance for towing, sled pulling, or street use—while maintaining factory fitment across all connections.
