Post subject:	Air filtration.
of all the discussion ive read, through the sticky's to the wiki's..... I have somthing to possibly... eh hem... possibly add here. ill make it short and sweet, then duck for the flying veggies and lynch mob if anyone is angered by this somewhat hot topic.... Re-visting filtration...... Amsoil "DRY" lifetime filter and other brands w/ similar product 1) anyone have a bead on this thing yet? w/ respect to the Extra dust from having less filteration angle? lead in to the K&N.. Do the DRY lifetime filters out there perform better than K&N with respect to this? K&N: 1) Re-oiled filter premise: how much worse is it to have the oil on the K&N getting in my engine vs my CCV oil spewing all over my turbo and intercooler? Its a bit upstream so maybe i ruin my MAF sensor, then i get a free ORM no extra charge =p So if my engine was designed to live a long happy life sucking in CCV oil and Exhaust gasses w/ particulate carbon in it (which grind away at my engine parts), how much dmg could that K&N oil cause? 2) Extra dust from having less filtration? Ok Yes Peace! The darn thing cant filter well, thats the point, hehehe. But if i use a paper one for dusty times like off road ect, isnt that enough? Especially given the following thoughts: 2a) In controled conditions(all things being equal) Paper filtration, prevents dirt intake by like what 1000% er somthing? Ouch =) But lets look at a real world situation..... a well maintained K&N vs. how most people treat their paper air filter? 2b) again Engines running cronicly VERY dirty Paper filters live a long healthy life, in most cases, somthing else usualy goes first and the car becomes NON-cost effective to drive. So, could one make a rough comparison between a poorly maintained paper vs maintained K&N as roughly equal? If so i dont see the reall issue here. All that nonsense being stated.. In a totaly ideal world i would want this: 1) CCV not oiling up my intake 2) EGR tossed in a ditch and not putting diesel soot all over my intake and sensors and what not. 3) larger air box increasing flow to engine while perserving "PROPER" filtration. Anyone running the snorkle yet? does it help keep dust out? ok maybe thats better stated in another thread.... Disclaimer: im posing questions w/ a bit of logic and intuition as background, i am not intending to state firm belief one way or another, with any of these aftermarket filters.... but some of these things got me to thinking and i thought worth sharing for discussion. So please if your passionate about this in some way that offends you, im sorry. I am interested in increasing air flow to my engine, AND keeping PROPER FILTRATION, but only proper to the point where its not the short stick on the death of my auto in is golden year. =)

Post subject:	Air filtration reality
I have placed a "Filter Minder" on the clean side of my air box and after several full throttle accelerations to way over the legal speed limit I have not had any measurable restriction on the intake. The stock Mopar filter is showing typical dirt/oil loading at about 8,000 miles of use. I do not believe there is anything to be gained in this area. Exhaust side improvements are somewhat effective, but in a completely computer controlled air management and fuel system, you are unlikely to gain much there except slightly reduced turbo lag. Reduced or eliminated EGR will give you the most bang for your buck because you will not be displacing air (oxygen) with exhaust. A turbocharged diesel engine only responds to adding boost, fuel and advancing injection timing if you want significant performance. Reprogramming is the only real way to get there. Beyond that you can run a bigger turbo for more air to burn MORE fuel etc. I think I'll just ORM and chug along at 25.5MPG avg. Just my 2 cents.

As for the Amsoil EaA201 dry filter...It has a MUCH LARGER filtering surface area...almost double the number of pleats and the pleats are a bit longer...I did a count and measurement a while ago, but basically you double the surface area of filtration.

The combination of the AMSOIL replacement filter mentioned by Darby and the gasser airbox improves filter life and engine breathing.

o8k The carbon that you are refering to is NOT an abrasive. See! We do luck out sometines! LK

LK Disagree: Work in a transit authority with a large fleet of Detroit Diesel EGR "clean diesels" where we see a significant amount of upper engine scour from recirculated soot. This is trashing engines in the first 25% of expected life in most cases. This problem is significant enough that we are going to bid to repower the entire fleet with Cummins or CAT.

We had a thread on this before (I think that I might have started it....getting to old to remember): The generally accepted conclusions: 1) Oil filters are bad for the MAF. So don't. 2) OEM filters are actually pretty darn good in the filtering department 3) The Amsoil filter is the best way to get more air (less restriction) without losing filtration quality. 4) The gasser airbox mod helps keep water out (water ain't good) but no proof that it is better or worse for airflow 5) Nobody could figure out another, bigger airbox that would fit in there. 6) Yes, virgina, the EGR is evil. ORM or better is very important.
