Engine/Transmission (1998.5 - 2002) air filters

[Kissfan113]

ok guys, looking at air filters for my truck, i really can't afford the afe stage 2 kit i want, i want to do away with the factory hose though. I have been thinking of a K&N Fipk GenII kit they sell for the cummins trucks. Suggestions anyone, workin on a tight budget waiting on enough for a comp box

I know this isn't exactly what you were asking for, but I have had great success with my BHAF.

Ditto there. $35 and you are done.

 

[Kissfan113]

really kinda looking for something a little different, with a reusable filter, I knew about the BHAFs but figured that the cost in the long run would build up, i also like everything to come in a kit when it comes to air filters too.

Not to say that what you are looking for is a good or bad decision. Just offering some info.



I think that there are some additional costs associated with the cleaning and reoiling of the gauze type filters. And if you factor in your time as money, well, you get the point.



Also, I know that others will not agree, and that's ok, but a paper element will outperform an oiled element everday for filtration. I know, I know, test data, this, test data that. . Well, all that data is taken when the filter is new. Paper included. But, after time, cleaning, reoiling, cleaning, ect, the gauze will become less dense and allow larger passages of space to form. The only way you get back filtering effenciency is to get it dirty. This in turn negates the whole reason of the thing in the first place.



I can say that all of my race bikes had oil type filters. Specifically Uni filters. Why? because they outperformed K&N and others every day. When I got a sponsorship and got new filters to just throw away (ie. not clean) I went to the K&N. Why? because they do flow better, but I had to tear the bike down on a more regular basis to maintain the level of performance I required.



So, do what you feel is best for you, I just want to share my experiences with you. And for factual data? Well, most of it was done by my engine builder looking for a way to stretch out maintenance. Truth is, out in the desert, you are gonna be hard on parts. I am not at that level towing my boat to the river. If I had a purpose built race truck, I would run a less restrictive element or maybe some wire over the inlet. (Just to keep kids out of the engine).

Both myself and my Dad run BHAF's on our trucks. He installed a filter minider in his to see how long it would take a BHAF to get dirty. He drove over 35K before the filter minder moved. This included two trips to Mexico (AK to Cancun and AK to Cabo) and lots of regular driving in Alaska (very dusty). Depending on how far you drive each year, you may have to replace a BHAF once a year.



As for a kit, yes it is all in the box. Take the filter out of the box. Rip your old filter housing out of truck. Put little black rubber feet from stock box on the studs sticking up. Stuff BHAF into stock hose and tighten clamp. Done.



Best $45 I ever spent (its more expensive here in AK due to shipping)

Kissfan113,



Take a look at our site for the AFE Pro Guard 7 intake, we are having a special sale and the price is veeeeery attractive. Plus the PG7 beats any washable filter out there for stopping dirt, in fact it's just a tick short of paper filter dirt stopping ability. Call us if you have a hard time finding it on the site or have any questions etc. Plus later you can add the Torque Tube and have a mostly Stage II system!

The stock box realy isn't bad provided you force ONLY cold air in it with a scoop and aluminum tape the big hole in the channel in front of the battery. I settled on a AC replacement for $25 bucks from www.rockauto.com since from tests that Iv read show the GM filter media superior in filtering to ALL the aftermarket foams. Compression is the holy grail of diesel health so I don't play around with all the hi flow stuff that was primarily designed to flow air for those spark plug units. heres the most difinitve test on the web sorry some of it fails to come up, and my air scoop link. With the MAD ECM boost responce is instantainious. I also screwed the fender tube tight in the air box with some self tapers. http://home.usadatanet.net/~jbplock/ISO5011/SPICER.htm http://www.dieseltruckresource.com/pics/showphoto.php/photo/10354/password//sort/1/cat/500/page/1

Has anyone used the AFE pro guard 7 stage 2 or the K&N intake system. I use the BHAF and it does fine. It looks like the AFE pro guard 7 state 2 may bring in cooler air due to it fitting in a "box. "

Thanks,

Greg

The Wix equivalent of the BHAF is the 42790 - we have them...

kevin stay away from the k&n FIPK systems... ... BHAF or a afe stage 1 kit would be your best bet. the only difference between the afe stage 1 and 2 kits is the turbo inlet hose... . and price... . the second part was the deciding factor in me getting a stage one afe intake. just my . 02 cents

After talking to enough people, I've decided to stay with the factory setup. If you get the truth out of most of us, it seems that these aftermarket filter kits just don't make enough difference to warrant the cost.

Thats a claim I don't hear very often. I do agree that the stock box is great for stock power and perhaps 50 additional HP. The BHAF can take a few more ponies and is a good alternative to the oiled filters for those that prefer that route.



However, my Scotty Air intake will reduce the harmful exhaust gas temperatures by 50-100F compared to a stock air box on a stock truck.

It is a two layer foam filter like that which is used in the BAJA. It will reduce exhaust gas temperatures better then any other intake out there. Its been proven on these trucks since 1997. Other companies saw this as a good market and created their own intakes to compete. This is whats great for the consumer... choices.



One also has to keep in mind that our next limitation to cooler exhaust gas temps is the turbo when adding power.



I felt the need to post this as I want to make sure people are aware of an option that could very well save you some damage from heat.



With oil analysis' coming in from all areas of North America with the highest reading of silicon at 7PPM [dirt], the UNI dual stage filter is doing a fantastic job at filtering.



Food for thought.

Scotty,

I agree about the turbo. My understanding, is that it is the biggest restriction in these trucks. As far as the aftermarket air filters go, I'll stick with stock, till I see something that's a considerable improvement, and does not increase cab noise.
