Rise in EGT with new Amsoil Air filter????

[Challenger-II]

Can anyone explain why did I see an increase in my EGT when I went from a stock filter to an Amsoil air filter? It runs about 100 degrees higher when into the pedal. This is post turbo readings. I also noticed that it is much more reactive too. EGT's rise quicker and also fall quicker. WHY???

I love the amsoil filter

Is the filter overoiled?

 

[Challenger-II]

No... . it isnt over-oiled to my knowledge. Amsoil tech line said to use about 2 oz for the entire filter. I drizzled it on both sides in a zig- zag,criss-cross formation and then rubbed thoroughly. Even did the edge foam. I placed saran wrap over the filter and rolled it with a rolling pin to distribute. No visible puddling of any oil. It was oily to the touch of course.

the filter comes oiled right out of the wrapper



why did you feel the need to reoil? just tryin to help



Too much oil is a real nono

Did some reading on the Cummins site last night. In their FAQ section, the question is asked regarding using any air filter other then Dodge OEM. The answer was that Cummins recommends agains't using any air filter other than Dodge OEM. I guess my question as a newbie is what do you gain versus the risk of screwing up your engine by going to this filter?

Bob,



I bought the filter used from a fellow TDR member who only used it for a month. He washed and dryed it prior to shipping it to me. I pulled off my tube going from the filter into the turbo and it is bone dry. No oil residue, so it definately is not over-oiled.



My quess is that the slight rise in EGT has something to do with more air flow over stock. You can hear this thing sucking in a whole lot of air!!

 

[Big White Beast]

More air shouldn't raise EGT's

More right foot while testing the new filter probably would though.

The reason you see higher egt is because the filter is more restrictive than the one you took out.



I suggest you try a K&N filter you will see a drop in EGT and 1/2 lb. boost increase.

Ted... . are you saying the Amsoil filter is more restrictive than the stock oem filter??



I thought the Amsoil was right up there with the K&N as far as airflow??

 

[Bob Wagner]

Keep the Amsoil its flows twice as much as oem filter.



The Amsoil is twice the quality of the K&N

 

[lschultz]

Ted I think you are wrong on this one.

 

[Ted Jannetty]

I am Not wrong.

I am not giving an opinion either way.

I am stating a fact based on the information that was provided.

If your egt goes up after a filter change then it flows less air, Period.

 

[MCummings]

Just Say NO to POLITICALLY CORRECT!





Simple fact. .

Change air filter + EGT's rise = Filter not flowing as much as previous filter.

Thank You!!!

 

[lschultz]

I guess I was a little quick on making that comment without seeing the filter. Sorry Ted.

If you would like another Amsoil filter for free (you clean and reoil)



I have a couple in hand.



Shoot me an email (pay it forward)

Well this may not be the place but I have used both the K&N and the Amsoil filter in the stock filter housing. I came to the same conclusion with both filters, neither is up my standards. The Amsoil being the worst for fit and function. There is just something about 2 or 3 inches of oil soaked foam that well, when install in my 4K dollar 2 stroke dirt bike is ok but not in the Ram. I just didn’t feel confident about using this filter. The K&N was a better filter but still did not seal the factory housing as well as the OEM filter. I will stick with the OEM air filter from here on out, when it come time to change the fluids again I will consider the Amsoil lubrication products because there are among the best. This is just my opinion, that being said I am prepared to take the abuse for forming my own opinion, be it not the popular one.

The K & N air filter made to fit in the stock air box does not seal like it should. I'm running enough boost that I pulled apart the one I tried. I removed it and took it back to AutoZone.

I ran a K & N RE-0880 with foam pre-filter, after removing the stock air box. That one was definitely better.

The Amsoil filter that fits in the stock air box DOES NOT have a terrible fit. That is a common misunderstanding. The foam edge is over-sized for the express purpose of gaining a tight seal all around the lips of the box. The lid compresses the foam. It helps to remove the lid completely to position the filter.

I've seen the Amsoil filter off my truck outflow the paper filter that came with the truck, new. This was done on a display/test stand that anyone can make, and is available for dealers to purchase to use at trade shows & events. I tried two others I had in stock, the results were the same. I tried the same comparision with a customer's new Chevy truck. The Amsoil outflowed his stock filter. He bought it on the spot, and put together with his new Flowmaster exhaust, he has gained 2mpg, not unusual for a gasser.

Challenger-II , you might have a bad filter. Yours is the first I've heard of that raised the EGT's. There are other factors to consider, though, such as the weather. If i were you, I might want to try switching back and forth between the two filters, making several test runs in ONE DAY, on the SAME ROAD, at the same speed, etc. The results would interest all of us... .

 

[Challenger-II]

THANKS for your reply Briar... . you at least offer a reasonable reply. It's a shame that some of the others are too busy trashing each other to answer my original question.



I just dont understand how the OEM filter could outflow the Amsoil. I understand the concept that change in filter + rise in egt = less flow, but it doesnt make sense. My rise in EGT was only slight and as I have stated, the temps are much quicker to register on the gauge both rising and lowering. I do feel a slight performance benefit. Seems to spool up a bit better.

You're welcome, Challenger-II. Keep in mind I'm not a scientist, or an engineer, I'm only relaying my honest observations about what I've experimented with.

MoparDave, you should be okay with the OEM style paper filter. But many of us are running larger turbochargers, and we need to flow more air. Hence the need to find an alternative to the stock air box.

The oil on the Amsoil filter is part of what makes the difference. It has more "tack" than any other filter oil on the market, allowing it to trap a lot of dirt. And a dirty filter just becomes even more efficient, up to a point. Washing these filters too often & too soon is defeating one of the design purposes of the filter... .

I'd recommend no sooner than 20K miles to wash & re-oil, unless you live in a very dusty area, or drive dirt & gravel roads every day.

The filters come from the factory with too much oil on them. Paper towels will take care of that quite easily.
