How to increase MPG in your dodge cummins pickup

This article is a simple and effective way to improve airflow to your dodge cummins diesel engine.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Ratchet
• Extension
• Needle nose pliers
• Wrenches
• Elbow grease (haha)

1. Ok first thing, loosen the bolts that hold on your intake elbow to your heater grid. Mine were 10mm. They are four of them. All easy to get to.

2. Unbolt the wire that runs to your heater grid. This wire can also be routed back to the starter selenoid and removed. I would only be cautious of removing the heater grid in a very cold climate.

3. Being careful of the two gaskets, remove the heater grid from the engine. You'll see the grid of coils that heats your air before it enters your engine. This is to improve cold weather starts.

4. Remove the two bolts running horizontal first. They are the easiest to remove. Then remove the two vertical bolts. Hopefully yours will be easier to remove than mine. It took some time and a few bloody knuckles, but it was worth it.

5. Once the bolts are removed, you'll have to plug the holes with carriage bolts. I used 3/8 carriage bolts with with the threads pointing out. On the outside I placed a rubber washer, then a metal washer, followed by a locking nylon nut. It would look better with the threads facing in, but I'm going for performance, not looks. If you keep the bolts small, it actually isn't noticeable. I used 1 1/4 inch in length.

6. 

   Now just put it all together. You won't notice a huge difference, but it will show a slight increase on your MPG and a little better throttle response. I removed my heater grid after installing an aftermarket intake elbow and still noticed a difference in power and MPG.

Tips & Warnings

• Have patience when removing the heater grid. Some are easy and others make you wanna throw that thing as far as you can.
• Watch your knuckles..the skin will grow back
