Gee you mean that extra HP from the K&N isn't enough?

Just my not-so-humble opinion, but I'd stay away from any sort of oil
impregnated air filter. They are notorious for providing less filtration
than standard paper and have a history of contaminating sensors on your
motor with oil mist. No thanks.

I don't know that you're going to do much better on fuel economy with
expensive add-ons and be able to recoup the cost through fuel savings.
Personally, I think you should stick with some of the absolute basics, like
a good synthetic oil regularly changed, fresh air and fuel filters, and even
a secondary fuel filter that screens particles down to 2 microns so the fuel
is as clean as it can be by the time it hits your injection pump and
injectors. That's all I've done to my '04 Silverado with the Duramax and
Allison, and my mileage check just this morning at the pump was 18.8mpg in
mostly city driving.

In addition, conservative driving habits will have a much more positive
affect on your overall mileage than almost anything else.

Cheers - Jonathan

Jonathan,

Could you provide some background references for your comments on oil
impregnated filters? I'd like to look into that.

You can search this and many other automotive newsgroups for dicussion
threads about these type of filters (mostly K&N because they are the most
popular). What it boils down to is a direct comparison of the
specifications from the manufacturers. K&N (and others) flow better -
mostly at the high end of the flow rate - but have a lower filtering
effeciency (total amount and size of particulate matter). The truth is an
ordinary paper filter still flows much more air than your vehicle will need
99% of the time and have a higher degree of filtering.

I have also read that both GM and Ford have put out bulletins limiting the
warranty on vehicles with an oil impregnated air filter installed due to the
high incidence of sensor failure from the oil mist. I don't know which - if
any - sensors would be affected on a Duramax diesel because the notice came
out for the gas motors, but that's more than enough for me. Maybe one of
the GM techs who prowl around this group can fill you in with some specifics
on this.

Cheers - Jonathan

Thanks, Jonathan. I appreciate the info and will check it out.

Hello Robert,

My 2 cents worth... You may find just as many K&N owners who will still keep
using their products as there are detractors for such oiled non-paper
filters. High quality paper filters do a better job of filtering the finer
particles (I find a thin coating of very fine black dust on the MAF screen
of our '98 6.5TD Tahoe, and also on the inner section of air filter pan of
our '86 6.2NA Sub).

I choose to continue using the product, especially on our Tahoe, because of
the reusability feature: the design of the air intake system in the Tahoe
draws so much crap into the inner fender, the air filter gets clogged
quickly with leaves, bugs, dirt and airborne hitchhikers (e.g., dandelions).
Those drum air filters run $17-$19 and have to be replaced at each oil
change even though I rotate them to expose a clean section to the "sweet
spot."

I've tried wrapping the K&N filter with about 10 feet of surgical gauze
sprayed with K&N filter oil to see if the deposit of fine black dust is
decreased but the results are not conclusive. I was going to try wrapping a
paper filter the same way but "Doc" said the oil, if it soaks the paper,
will decrease the air flow of the filter -- may still go ahead and try it,
though.

How much damage the fine dust particulates will cause is still up for
debate. I'm more concerned with the quality of the diesel fuel the engine
ingests.

Good luck! Franko...

I have 40,000 k on my 2004 3500 Dually,4x4,LT,LWB,Crew-Cab.
I haul campers all over the country. I can tell you for a fact a Duramax
does not need anything. I am going to run a 5 inch exaust because
several of the guys running them on their Chevy's,Dodges and Fords say
they have an increase in torque power and fuel mileage. I did talk to a
guy who has the same truck as mine and he added a 70-75 hp chip. he said
he wished he would have saved his bucks. I also have the K&N. Most of
these guys also run Lucas oil everywhere they can on their trucks. They
are all very impressed with this product. I know 2 guys that have been
using it since day one and both trucks have over 300,000. No Engine
problems to mention. One was a 1999 7.3 liter Ford Powerstroke and the
other is a 2001 Duramax... The air filter and exast is all I am doing to
mine....

Have a Great One !
Bob
