best air intake for towing?

[ataboc]

Have an early '99 F350 PSD & I pull a heavy gooseneck horse trailer with a fair amount of hills where I live. Replacing stock air box and wanted to know what would be the best air intake that would give me some more hp but would still give some good filtration. Filtering is more important for me but I don't want to choke the engine either. Any help is greatly appreciated.

The Ford AIS is about the best filtering but flows somewhat better....

I agree. Or you could go with a DIY intake setup..run ya about 60 bucks or so

if your going after market intake the best one for the money is s&b intake ....contact raul from stealth automotive he is a site sponser here he will hook you up

Best filtering and flowing system is a Tymar or clone period.

I'd go Ford AIS. Nice little set-up, do the fender sleeve mod on it and it flows quite a bit of air over the stocker. Plus, it looks like a factory piece and is still quiet in the cab.

I did the DIY intake and man it whistles like crazy... but i like it. Feel like I gained a bit of power.

I did the ford ais on my late 99 like the looks better than stock and now optima batteries will fit without a problem powerstrokeshop.com had a great deal on them and replacement filters and were good to deal with. The filters are the drawback of the system costing up to $100.00 depending on where u buy.
