This is my first CTD, I was looking under the hood the other day and noticed the filter minder on the air filter was pulled in about 3/4 of the way. I pushed the button and released it, drove it the next day, checked it again, it was pulled in again. Is this normal, I have always owned Ferds and I never saw it pulled in on one of them. What would be the best upgrade for this filter to keep from starving this for air?

 

I vote for the Amsoil Ea189 Nanofiber filter.
Another mod you can do is add a hole at the bottom of the airbox for increase airflow.

I second the Amsoil and air box mod.
Iv got the Amsoil filter and love it. Doing the airbox mod this weekend.

 

Lots of good filters out there - I'd just be wary of the Purolators. The Mopar filter has two elements: a paper and a "brillo pad"-esque topper. The Purolator filter is just paper.

As for the air box mod, I know a lot of guys around here do it. I just can't figure for the life of me why Dodge just wouldn't have put that hole in at the factory if it actually made a difference in airflow.

But my comments are by analogy only - a better set of comments would be backed with a dyno chart, EGT readings, or something more substantive. I guess I'll just finish off with an "IMHO".

 

Do a search on this forum or on the performance and accessories forum, and you'll have hours and hours of air filter. air box, hole drilling, make your own from parts found at Home Depot, etc., etc., reading.

I also vouch for the Amsoil filter - I put mine in about 3K miles ago - just checked it - no dirt around the seals, and the filter minder hasn't moved at all. I seem to be hearing more turbo these days too, but that could be my imagination. My egt's seem to be about the same, but it appears that it may cool off a tad quicker - but again that could be my imagination.

 

I just orderes the EAA189 Amsoil filter yesterday. After many hours of reading I feel this is the best filter for what I need right now. Inexpensive ($57.00 delivered to my door) and cleanable with NO oil to add. I will probably do the airbox mod as well.

 

What's the oem airfilter part number?

 

Is the Amsoil EAA189 filter a flat panel type filter - in other words an exact replacement for the OEM filter?

(I've checked the Amsoil website, but I couldn't locate a picture or a clear description of the EAA filter for the CTD)

 

Yeah,it's a flat panel exact fit replacement. On the TDR site,a dyno test with different filters proved no measurable difference between aftermarket and stock air filters on a stock engine. Next question is...how many keep their truck stock?

Yes it is normal. No need to change the filter until the minder says to make the change.

I just changed mine at 83k miles, almost all highway. Some say that this is way to long to make the change. The filter minder stayed around 60% until the mileage was up there. I did not seem to loose any power, it always had plenty of pulling power. I monitored my EGT and Boost before the change and can see little or no change in the readings or any increase in power. Although I am sure that there is an increase, I just cannot tell in the feel of it.

Some say that a dirty filter will reduce your fuel milage, I don't think so ,you will only get a loss in power. The computer controlled engines, including gas, will only put in enough fuel to burn completly. This is controlled through the oxygen senser in the exhaust. That is why the newer diesels do not smoke like the older ones.

I installed a Fleetguard filter from Geno's (around $13) and the filter minder is now at the lowest level.

I do not go along with adding a hole in the filter box as this will increase the amout of dust or dirt that can inter the filter chamber. The cleaner air will always come from the front of the vehicle. The only reason to change the air intake setup is to increase power as many do. Mine will stay stock, it has all the power I need.

 

My filter minder NEVER moves. I change air filters when I change the oil @ 10k miles - mostly highway. Every once in awhile, before changing the air filter I will take it out and thump it on the ground, removes alot of bugs & loose dirt. I was also curious about cutting a hole in the box, but have to agree with you that it would seem to allow for more debris, bugs and water to enter the box and shorten the life of the filter??? I'm NOT saying it would, cause I've never done it, I'm just wondering as I see all the crap that comes in from the front which has a shield on the intake.

 

My truck is a farm truck ,the OEM air filter only lasted me 500 miles 6 months...I went with a K&N drop in (fits in the stock airbox) I get plenty of air from the stock box and I DID NOT drill a bunch of holes !I think the hole in the stock box is big enough...I have 21298 on her now and the K&N is still fine

HOWEVER ,let me say this the K&N is "cleanable" BUT I will just buy another when it is time ,rather than cleaning and re-oiling this one...LOTS of problems can occur from over oiling them and it is real easy to do ,I guess

The OEM is $15...K&N was $70
OEM lasted 500 miles, K&N still fine @ 21,000

just my .02

 

What is a air box mod?

 

My stock took 20k miles to pull the filter minder spring over, and Fram filter took about 2k miles. Now I'm trying a Napa Gold(Wix). The problem with the Fram is that the paper creases all suck together, and then the air can't pass between them, the Wix filter has bumps between the creases so the air can flow between the folds , it's amazing what a few more bucks can buy.
