If you own a 6.7L Cummins-powered Dodge Ram and are serious about intake improvement and better reliability, by throttle valve delete 6.7 cummins now you should have heard of the throttle valve delete. This simple modification can give any noticeable gains in performance, decrease exhaust temperatures, and extend engine life, especially when done alongside an EGR delete. One of the biggest-selling options out there is the OSIAS 6.7L Cummins Dodge Ram EGR Delete Kit with throttle valve cooler.
Let’s break down what exactly this upgrade entails, what benefits it gives, and a few things you should know before you install it on your rig.
What is a Throttle Valve Delete?
The 6.7L Cummins engine features a throttle valve in the intake manifold. The factory purpose of this valve is to regulate airflow whenever the EGR (Exhaust Gas Recirculation) system is active. Once deleted, the EGR system may render the use of the throttle valve unnecessary or maybe even restrictive.
A throttle valve delete replaces the stock valve assembly with a straight pepper-pot type of connection, eliminating the butterfly flap that can suddenly close. A smoother, less restricted flow path is formed which now goes straight into the intake manifold.
Why It Is a Smart Upgrade
Better Airflow and Performance
Basically, it just allows the engine to breathe better without restriction set by the stock throttle valve. This would translate to improved throttle response and helping the turbo to spool faster when under load.
Improved Reliability
After the EGR deletion, the throttle valve can still close or malfunction, causing power loss or rough running. Deleting the throttle valve removal means such weak points would not exist.
Lower EGTs (Exhaust Gas Temperatures)
Better airflow means less strain on the engine, hence cooler operating temperatures when the engine is needed to push hard: towing or in hotter climates.
Cleaner Internal System
No EGR and no throttle valve meant that there would still be some cleanliness in the intake manifold- thus reducing carbon buildup and improving future engine reliability.
About OSIAS 6.7L Cummins Kit
The OSIAS EGR Delete Kit with Throttle Valve Cooler is designed for Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins engine. It provides all the necessary components to remove the factory EGR system and the throttle valve assembly.
Some of the highlights are:
- Durable, heavy-duty materials are heat resistant.
- Direct fitment for many 6.7L Cummins trucks (especially applications on 2010–2014 models).
- Designed to promote airflow efficiency and intake cooling.
- Applicable for performance and off-roading purposes.
- This all-in-one solution streamlines EGR and throttle valve products into one complete package, making installation an effortless task.
A Few Things to Be Aware of Before Installing
1.Compatibility Always Check to See if Your Kit Fits the Exact Year and Engine Version of Your Truck.
2.Legal Use Generally, EGR and throttle valve deletes are specified for “off-road” or “competition use” only. Be sure to check on the legal aspects in your area before installation.
3.Tuning Required Post EGR and throttle valve delete, the ECU will need a tune to delete fault codes and to ensure optimal performance.
4.Installation by Qualified Personnel The OSIAS kit is designed for an easy bolt-on fit, but a proper install requires basic mechanical skills and attention to detail.
5.Maintain Records Follow exhaust temp and turbo performance post-delete to be sure that everything works smoothly.
