Why don't we ever discuss air filters?

[huntergreen]

Don't need a blind study to know I love the sound while driving it. That's reason enough for me. Never mind the extra 15 hp they claim to have added on a dyno .

Looking at catch can now.

You can get a BT catch can from Moe's preformance, a vendor on the forum with a stellar reputation.

Gotcha. Well with the Legmaker they have you relocate that sensor. Wondered if that caused any problems for anyone.

That is just the air temperature sensor you have to relocate, which isn't too big of a deal.

I just made my own mid tube using about $50 in parts for a aluminum tube and 2 silicone couplers and hose clamps. No problem yet with it. Got the idea from someone else on the forum.

Wow... that is a lot of responses... to air filters.

I guess one advantage of having a six-banger under the hood is that I'd die of laughter if someone tried to tell me how I could increase the performance of my motor by bumping in specialized air intake rigging... I mean, you'd have to slap on a supercharger before you'd squeeze out more hp from that little thing...

This thread is not about air filters that increase power.

OEM Mopar ones for me

I agree its not about air filters that increase power but every air filter thread always turns into "I can feel the extra power that my K&N drop in filter gives me" thread at some point. Of course since Burla started the G-D thing we know his intentions are purely from a good maintenance perspective. I still firmly believe that users of non paper /reuseable filters will see higher silicon numbers in their UOA's which can't be good any way you look at it.

I'm looking for where they mentioned in a thread on a different forum.
Here are some side by side comparisons to a Fram and Wix air filter compared to the Mopar which is made in the USA(others made in China)View attachment 161017View attachment 161018

Be careful. A simple comparison based on the size or amount of filtration element cannot determine the flow characteristics because not all filtration papers are the same.

The filtration element (paper) is selected by engineers to meet a specific air flow rate and particle retention. The air flow pass rate is determined by the porosity factor of the filtration element. One cannot determine what the porosity of the filter paper is just by looking at it, or trying to compare physical size to another.

The standard automobile industry standard is to provide the necessary flow rate for a specific engine at 1-2 micron filtration with a 95% retention.

It should be of no surprise that filtration paper made to trap 1-2 micron size particles would be more expensive to manufacture than 5-6 or 10 microns, which can be found in less expensive air filters.

As for wet filters, the hype of increased air flow is usually offset by contaminated Mass Air Flow sensors and increased valve wear.

This... this right here. It rings a bell for me not because of anything automotive, but I think what does come to mind might explain some stuff anyway.

I live in the sticks. As part of living rural, among other things, I am my own water department. The well is 140' deep, and pumps a beautiful and constant 46gpm. Problem is, while it's perfectly potable as it is, the stuff has a lot of Iron Sulfide in it - harmless, but stinky, and leaves red iron stains all over everything.

So - I filter the water.

I have a wide variety in filter choices, but I'll save some time and cut ot the chase:

* The OEM filter (Pentek BB-20 Carbon) is 0.5 micron with a carbon filtration core, costs $60 each, and lasts 8-10 weeks on average.

* The cheaper $30 filter elements (usually made in China by folks like RonAqua and Tier1) range from 5-20 microns, and last only 2-4 weeks before the carbon is shot, the filter wears out, and the yucky sulfury scent returns to my faucets.

So what's the point? Well - you get what you pay for, yes, but going cheap is often more expensive in the end.

Now, back in the automotive world? Holy crap, y'all... unlike the overly-damp world of water filtration, OEM paper filters for the truck are often quite cheaper than the semi-exotic bullcr- err, I mean - products that they sell to allegedly increase performance (though a bit more than the cheapie paper stuff on the back shelf at the local WalMart/AutoZone/O'Reilly's).

Kind of a no-brainer here.

Used a K&N drop in for 180,000 miles in a 2003 5.7 . Never contaminated any sensor's. Not having a catch can sure did gum up the throttle body though.

I'm surprised it still ran with all that extra valve damage.

This is why. Good find by Corey (h395).

I am still on my factory air filter and I live on a gravel road, 8+ years later, and yes I check it every year. I'm likely gonna replace it soon just cause, but I have never been on board with all of these filter upgrades because the oem is so good. I'm not knocking those products, I'm just saying I aint fixing what aint broke, and I like the factory air box. discuss?

I agree Burla. I've just done my second oil change this morning.
I use 5w20 PUP and a Wix sp filter. Checked the OEM sai filter at 40km or 24k (USA) and looks brand new. As Burla said, why change what ain't broken!!

 

[Hemi395]

So I would pass on the ACDelco filter. I'd get the 6.4/EcoD filter, much taller pleats and very well made. PN 68190705AA

In the pics Left to right, 6.4/3.0 Mopar filter, 5.7 Mopar filter, 5.7 ACDelco filter

 

[Burla]

Wow, great work Corey. Don't settle, in this case you need Mopar Filters. The replacements will move around.

Now that you have been running this for a little bit... any increases in sound, mpg, throttle?

I just put the 6.4/3.0 filter in this afternoon so I can't really say much about mpg but there does seem to be slight increase in throttle response. Makes sense since this filter was designed to feed a turbo motor and the HD 6.4 Hemi. As for sound its pretty much the same as the 5.7 filter...

 

[TXCOMT]

Good stuff here; when my AEM Dryflow filter wears out, I'll be sure to get a Mopar 6.4...oh, wait.

Have you had to clean it yet?

Not yet...it was only mildly used when I bought it off a member here, but I'll probably do so soon. I'm due for a TB cleaning, so I'll handle 'em both at the same time. Mileage now is 41K.
