Important Fitment Information

This installation kit is designed specifically for 2011+ Cummins ISX and X15 single cam engines equipped with the factory VGT exhaust manifold.

The OEM VGT manifold uses 12 standard-length manifold bolts and 12 standard-length spacers, providing consistent clamping force across all manifold mounting locations.

If your engine has been converted to an aftermarket T6 non-VGT exhaust manifold, this is not the correct installation kit. T6 manifold conversions require different hardware, including 10 standard-length bolts and spacers plus 2 shorter bolts and spacers beneath the turbo mounting flange.

Why Replace Everything?

Replacing an exhaust manifold is the perfect time to replace the hardware and sealing components that have been exposed to years of extreme heat, vibration, and thermal cycling.

Old manifold gaskets often fail to reseal once disturbed, bolts can stretch or seize, and spacers can become corroded or worn. Replacing these components helps ensure proper manifold alignment, even clamping force, and a long-lasting, leak-free repair.

With new manifold gaskets, a fresh turbo mounting gasket, and all-new mounting hardware included, this kit saves time, eliminates unnecessary trips to the dealership, and gives you everything needed to complete the installation with confidence.

Whether you're replacing a leaking exhaust manifold, servicing your VGT turbocharger, or performing preventative maintenance, this complete installation kit provides the components needed to get the job done right the first time.
