Thought I'd share this with the forum, the Ecodiesel lower airbox takes the same air filter and top lid as the 5.7 trucks but has an inlet that is roughly 50% larger. The part numbers for these are:
Lower Box: 68232657AC
Links to where I got them:
I took a pic of my Trinity with some air intake PIDs to show it flows really well.
These parts cost around $60. So for those that want to keep things all factory parts but want to have a better flowing intake without spending hundreds this is a good choice.
Please note this is not needed on the 6.4 trucks as they already have a lower intake box that uses the bigger Ecodiesel inlet tube.
You can see by the "P-RAT MAP BARO" pid that it hit 1.00 which means the engine is getting air equal to barometric pressure. This means the intake has virtually no measurable restrictions. The OAT was about 35* that day which means the engine is injesting air 7* above ambient temp. "MAP VAC" goes down to almost 0 almost every time the throttle is pressed confirming the P-RAT value.
Thank you very much. I just got the whole Eco airbox on eBay, the whole top and bottom and and intake and everything for 70 bucks. I just took the lower bits and popped them on. Took like 10 minutes including one beer.
I took a test drive and honestly can't tell if it's better but I like it. I tow a travel trailer so more air has to help. Still has stock looks, but better than OEM. I had them next to each other and was very surprised at the difference.
