What air filter?

[EvansF250]

I have a cold air intake with a Spectre filter. Thought about switching to a K&N but heard stories about them dusting the turbo. Is their any other brands to consider? What are your guys thoughts and experiences.

Spectre's can implode.
Do the DIY intake. I use a Baldwin. Donaldson is the 'original.'

Welcome to guzzle's 6637 Filter Restriction Sensor Web Page

or

Ford AIS Severe Duty Intake System 98.5-03 7.3L Powerstroke FA-1759

Sad but the price of the AIS just keeps going up... I payed $190 for mine... The AIS will work fine up to 425 brake HP...

The 6637 is a very good filtering & Flowing Air Filter System for the 7.3L.

I just didn't want an open air element...

Just Say NO! To K&N on these trucks... They are for racing, but that's about it... They are not a good fit for Working Trucks...

Ahh yea, but,,, Everything except the AIS looks kinda cobbed-up to me The AIS is just So CLEAN looking, like it Belongs there.....

Out looks, out performs, and unfortunately out COSTS too!

ANYTHING but a K&N though...

I have the AIS and ended up cutting the extra hole to let it breathe through the inner fender. The plenum they supply is just too small.

DIY with the NAPA 6637. had to modify the plastic battery housing a little. took about 30 min. I noticed the power in the seat of my pants. Got 30,000 miles on this filter and still flowing like new.
