For those running a DIY 6637 intake, how often (roughly) are you having to replace the filter? At $40-50 a pop for the filter I don't want to have to be replacing it very often if I put one on. Do the filter socks extend the life of the filter quite a bit, where can I buy one of those and how much $?
Before you tell me to check fleetfilter.com I already did $40 after shipping to my door for 1 filter, I can buy one at the local Napa for $47.89 and not have to wait for it to get here. The PMS is hitting full force, I need to start somewhere!

 

Personally, I change mine every 15,000 - 20,000 miles.

I'm not really religious about the change intervales, so when I see that it starts looking grungy, it goes.

I know some here like to run more miles on their 6637, but I would rather have several small charges for air filters (have been about $30.00 a pop when ordering 3 at a time), than one big charge for a replacement turbo (or worse).

JMO,

So one filter a year (or longer) depending on how much you drive and conditions? Sounds good to me!

 

I disagree. When the turbo goes this is what I like to call "a justifiable upgrade."

 

I just changed my filter this time after it being in use for a year. When it looks bad replace it. No worries if you go over, its only going to hurt your mileage.

 

Also, if you're paying more than about $35-$37 for the filter, you're paying too much. They run right at $27 each plus about $9 shipping from www.fleetfilter.com, and it's even cheaper if you get at least two at a time. Their delivery is really fast and reliable, too. Here's a link.

Regarding the cover... the degree to which a cover can extend the filter's life will depend strictly on the type of dust and dirt the filter is exposed to. Super fine dust will pass through any cover moreso than will coarse sandy grit, leaves, bugs, or birds (don't laugh... I've already experienced the bird thing myself). Either way, a cover cannot help but help, as long as it doesn't create too much air flow restriction itself.

It's a balance of competing objectives, so to speak... the tighter the cover's weave/knit, the longer it will protect the filter but at the same time the more restrictive it will be to air flow. Personally, I've found that a dirty filter will hurt my mileage, even with a clean cover, and that a dirty cover will not hurt my mileage, even with a moderately dirty filter.

 

O.K. lets put this in perspective. A stock panel filter from autozone runs between $18 and $24 so lets just say you get one for $20. now if a fleetfilter.com 6637 runs about $35 (if you order two and save on the shipping) you are only talking a difference of $15 (over the stocker) for much better filtration, and more airflow. Change at a little longer interval than you would a stock panel (I run my 6637 about 25K when its just hiway driving) so at 50K miles you have changed 3 panels for $60, or 2 6637s for $70 the longer you stick with the 6637 the less it will be.

If you are driving in dusty areas then you should be using the AIS which is more expensive.

 

I could not believe the difference a "gray" (same as the metal webbing) filter made over a new one. I picked up three pounds of boost and could hear the turbo whistle as low as 1100 rpm.

 

I pay just under $28 for a 6637 at my local NAPA. I have to pay sales tax but no shipping.

 

My local Napa quoted me $47.89 for the 6637 (I live out in the sticks). I'll have to do more research on the AIS intake- the truck will probably spend most of its time in cleaner air, but camping/dirt bike trips and windy days will bring their share of dust.

 

Please tell us how many miles a year means for you. Inquiring minds want to know.

 

Oop's, Time to change my filter, and buy a cover from pete.

 

just my .02. i really think that the AIS makes that much difference in performance, i have run both and currently have the 6637 in one truck and AIS in the other. the truck with AIS has more pick-up than the 6637, but that is JMO.

 

Ohoh, you just gored a sacred cow Mike, better put your flame suit on.

Pretty soon you're going to have a title like mine in your signature if you keep this up.

 

hey clux i did say that i am running both, so i have nothing against the 6637. just trying to stay honest here
