BENEFITS

The COD system is a weak point in the 4.0T. The lobes for each cylinder slide on a spline on the camshaft and over time wear and get stuck. If this happens, the car will be go to limp mode and run very poorly. Many aftermarket tuning companies already disable the COD system. This kit allows you to go a step farther and completely remove the solenoids and plug their holes. Doing this saves 2.5 lbs, and if you remove the wires as well, makes spark plug and coil pack servicing much easier.

CODING OUT

YOU CANNOT CODE THESE OUT VIA VCDS OR SIMILAR. EVEN IF YOU HAVE COD DISABLED IN YOUR TUNE, THAT DOES NOT MEAN YOU’RE GOOD TO GO

These must be coded out in your tune. OTS tunes do not have this done. Most tuners do not know how to do it. We recommend this service to properly code them out in your tune.

PHYSICAL INSTALLATION

To install, first remove the COD solenoids by gently prying them or using a pliers to pull up from the body. They’ll come out easy if you pull straight out. Transfer over the o-ring from the solenoid to the delete plug and press firmly into the hole to seat the o-ring.

Careful not to drop them; they fall into some weird places and are not magnetic…
