Best Air Filter and System???

I have a 2000 PSD. Great truck. Use it almost exclusively for towing heavy trailers. no problems except fuel quality which caused poor mileage and power. Anyway, I currently use a K&N Air Filter. But, I hear those are no good? poor filtration.
what filter to you recommend? and why?
thanks

 

some air filter options

i am running a airaid intake but there also are some other good options such as ford AIS intake you can finde one at www.powerstrokeshop.com click on special and then scrole down,
AFE stage II, or a do it yourself TYMAR intake.

 

I have the afe 1 with pro guard 7 filter media. I have received good tests back on my oil with it. Low Silicon. You might want to get a Pre Wrap for it though to keep the larger obstructions out of the pleats.

 

I use an AMSOIL Power Core Air Filter in my 2003 F350 with the 6.0L PSD. AMSOIL just came out with a new intake and filter for the 7.3L PSD:
AMSOIL 7.3L PowerStroke Air Induction System

 

Nice looking setup. What does it set you back?

 

AMSOIL policy prevents me from quoting prices online, but I dropped them to you in a PM.

 

that AMSOIL intake looks alot like the ford AIS intake. i wonder what the price difronts would be.

 

It may be as AMSOIL makes this statement on the product page:
"The Donaldson air induction system is three times more efficient than the industry-leading cellulose media. The layered structure from PowerCore technology is totally non-metallic and allows for 99.95 percent efficiency. The highly efficient Donaldson PowerCore air filter is the only aftermarket induction system that is approved by Ford Motor Company."

I suspect that the filter element is probably different that what Ford is selling, but I really don't know.

As I mentioned above, I can't quote prices online, but if someone knows what the Ford AIS system costs, I can let you know if the AMSOIL system is over or under that price, and if anyone wants specific pricing info, they can drop me a PM.

 

the ford AIS runs around $290.00. but it is on sale for $198.19 on the web address in my prev. post.

 

Those prices are slightly under the AMSOIL retail and wholesale prices respectively. However, the AMSOIL wholesale price isn't a sale and should remain fairly constant all year.

 

I've heard that the Ford AIS filter is capable of holding up to 3 pounds of dirt before a noticing a decrease in airflow. Ford is also denying warranty claims if poor air filtration is found to be the cause of turbo or engine failure. If I had to do it all over again, I'd put the AIS in my truck.

 

This is a Donaldson filter system made by Donaldson. Ford is also selling the same thing. This is a very good filter. This is what I have been useing for a year and half now.
