Description
The 6.7 Cummins throttle valve on a stock engine works together with the EGR system to re-circulate exhaust gas through the intake to lower tailpipe emissions. But on off-road performance diesels, it can be a dangerous liability!
One part of a complete EGR delete that is overlooked by most Cummins owners is the factory throttle valve. With the stock EGR system in place, the stock Cummins throttle valve will open and close to adjust the ratio of fresh intake air to re-circulated exhaust gasses. When it’s completely or partially closed, the engine draws the air needed through the EGR system. But when the EGR system is removed, there is no alternative source of intake air when the throttle valve closes. To get around this, the operation of the throttle valve is usually coded out entirely for most EGR-less tunes and the actuator itself is left unplugged. Sometimes the throttle valve can move unintentionally to a completely or partially close setting which leads to cutting off the air supply to your Cummins and suffocating it. This can cost you power, shut your engine down entirely, or even cause catastrophic damage if it happens at higher RPM. Even when open and unplugged, the stock 6.7 Cummins throttle valve obstructs smooth airflow through your intake. Don’t take the chance that your old throttle valve will stay put. Pick up the Sinister Diesel’s Throttle Valve Delete for 6.7L Cummins engines and put the finishing touch on your EGR delete.
