A throttle valve is one of the main components responsible for fuel dosage in vehicles with internal combustion engines. It regulates the amount of air entering the engine and is located between the intercooler and the engine on the driver’s side.
Therefore, the correct and reliable operation of this part is the key to the maximum power use, and mainly determines the environmental friendliness, efficiency, and reliability of your vehicle.

Symptoms of a foul throttle are usually the following: vibrations at idle speed, twitches during acceleration, hang-ups, weak bottom-end response, and problems when starting the engine. There are also system errors in the ECU related to the throttle valve.
As a result, the inlet system requires constant cleaning and costly repairs, which can be neglected by removing the valve beforehand.
A throttle valve delete is one the most effective upgrades you can do when deleting your EGR and or DPF for off-road use.
It prevents the stock butterfly valve from closing shut and causing intake issues (this part is only to be used when doing an EGR/DPF delete which will talk about a bit later). A throttle valve delete kit is used to remove the “butterfly” which leaves zero chance of it accidentally closing.
It is installed simply by removing the four bolts that hold the throttle valve assembly in place, removing the boot clamp, and then reinstalling.
You will experience an improved overall performance from your diesel as well as increased airflow, less turbulence, turbo spool and lower EGT’s.
Here’s the list of top delete kits you may need for your Ram’s engine better life.
The Best 6.7 Cummins Delete Kits for Dodge Ram Reviews
MIZZLES Valve and Throttle Valve Kit — for Dodge Ram Cummins 6.7L
Want to get more power and better fuel mileage from your 6.7L Cummins powered Ram? This MIZZLES Valve and Throttle Valve Kit is designed to recirculate your engine coolant faster than the stock EGR system for cooler engine temperatures while also allowing your 6.7 Cummins to breathe easier by eliminating sooty exhaust gasses that pass through your intake manifold with the stock EGR system in place. It guarantees improved exhaust gas flow.
Note: race tuning is required to prevent an illuminated check engine light. This will not fit cab and chassis models. Not legal for sale or use on pollution-controlled motor vehicles anywhere in the U.S. Legal only for off-road.
NEXGEN PRODUCTS – Throttle Valve Kit — for Dodge Ram 6.7L L6 Cummins Diesel Turbo
Replacing the factory butterfly valve between the intercooler and intake horn may be a pleasure with this high-quality kit. The same as many that cost x3 times. You won’t be able to notice a difference. Pressure tested. It provides increased airflow.
All hardware included. Quicker turbo spool. Buying this one you get a nice kit for a good price, look and fit. Easy to install.
Note: make sure downside bolts are not too long before you buy.
What is EGR Removal for?
The Exhaust Gas Recirculation System (EGR) is installed in vehicles to reduce the level of nitrogen oxides in exhaust gases.
This is done by returning some of the exhaust gases to the inlet manifold, thus reducing the amount of oxygen in the fuel-air mixture and the formation of NOx nitrogen oxides. Shortly, its purpose is to recirculate some exhaust gas back to the engine’s cylinders.
This reduces the engine power of the vehicle, as well as causes soot and resin to enter the engine, causing wear and tear, and oxidizes the engine oil faster which has a very negative impact on the engine’s life.
Owners of diesel Ram equipped with EGR and DPF sooner or later face problems that arise as a result of these necessary for the environment, but extremely hostile to the engine and the purse systems.
You will gain an HP advantage, mainly because the exhaust gases injected are hot. At the same time, MPG would be slightly degraded by removing the EGR, for a couple of reasons.
First, the retarded timing necessary and secondly because the mass of the inert gas will reduce manifold vacuum (which will slightly reduce pumping losses) as well as slowing the burn rate (already burnt gasses will not re-burn).
Thus, the usefulness of the EGR is twofold and is questioned even by environmentalists. Disabling the EGR system does result in increased emissions of nitrogen oxides, but the emission of soot, carbon monoxide, and carbon dioxide is significantly reduced.
Another important fact is the reduction of fuel consumption and the increase in engine power when the EGR is unplugged.
EGR systems have been known to cause serious issues in an engine, including stuck valves, coolant problems, and leaky cylinders.
In cases where the EGR system is faulty (e.g. the EGR valve is not working properly), there is no talk of eco-friendliness at all, while the engine wear and tear increases dramatically, the air-fuel ratio is affected and the vehicle may work very unstable.
This can cause a reduction in power, acceleration, and fuel efficiency. It can also cause rough idle or a Check Engine light. In this case, expensive repairs or completely deleting the system is required. And of course, it is worth noting that with low fuel quality the EGR valve fails fast.
Any problem with the EGR will manifest either as increased fuel consumption or reduced performance. Learning when to have it maintained or replaced is therefore important.
An EGR delete kit removes the EGR system and allows a vehicle’s engine to run at cooler temperatures. This improves performance, makes an engine run cleaner, and last that much longer.
Some of the signs that could point to a faulty EGR include:
- An EGR valve that is stuck open: if your truck has a mechanical EGR valve and it happens to be stuck open, it will act as a conduit which causes a vacuum leak in the engine. Some of the manifestations of this include rough idling and even a feeling of hesitation when you try to accelerate. When the problem is severe, you will also notice the truck stalling frequently. When the EGR valve is stuck open, it means that all the exhaust will be rerouted to the combustion chamber, which means that there will be little oxygen which is what is needed for the combustion.
- A valve that is stuck closed: on the opposite end of the spectrum, you can also have a valve that is shut and won’t open. In such cases, there will be an increase in the quantity of nitrous oxide gas in the cylinders, and this will manifest as the engine knocking.
Some car owners try to shut down the EGR mechanically by shutting down the valve. However, in most cars, this procedure causes an error Check Engine and even to the emergency operation of the engine with loss of power.
Proper shutdown of the system implies both physical shutdown and mandatory software shut down in the engine control unit.
Considering the above factors, it is recommended to switch off the EGR system as soon as possible before it starts to malfunction and thus wear out the engine.
A few more pros and cons.
- Without EGR, the oil lives much longer, lower quality fuel can be used and the inlet is not blocked by soot.
- The downside is that it takes longer to warm up during winter. The exhaust smells like diesel and not like ironed shirts… Also, due to the increased capacity, the load on the transmission increases.
So, you have to think with your head.
Be safe and long live the engine!
