One piece billet valve cover fits 1994 to 1998.5 Cummins 5.9L 12 valve engines.

Notched to fit over stock injection lines.

Also acts as a girdle for the rocker pedestals to help stabilize them when using high spring pressures and rpm.

Designed for aftermarket injection lines run either over top or around front and back of cover.

Comes with two -12AN ports in the top of the valve cover unless otherwise requested.

We designed it to clamp the valve cover wiring harness and seal but avoid pinching it and causing damage to the injector wiring harness.

These valve covers are made from aircraft quality 6061-T6 aluminum, and come with all stainless steel fasteners.

A baffle system was incorperated into this valve cover and was extensively tested.

If your engine does not not have excessive blow by you will not need a catch can.

This is a big step forward in the aftermarket valve cover market.

Multi-color RGBW Leds are an option and come with a wireless color controller.

If your engine does not not have excessive blow by then you will not need a catch can.

The breather is threaded for a -16 o ring fitting if you want to use your own fittings and hose.

We also decided the best option was to re-use your stock oil cap with a billet cover to set off the look.

We have seen all billet caps get either too tight or loosen up, as well as get very hot when the engine is up to temp and the cap needs removed.
