I just orderd the filter #46637 from fleetfilter.com. It was $19.xx + s/h. Napa's filter is over $46.00. It's tempting to order 10 filters at that price. Easy looking mod and with the new exhaust coming, I'll make a day of it.

As much as we try to keep on track, these threads seem to take several turns in their journey to the archives.

When it starts as a Kwik Filter question and ends up as a recipe for chicken soup, then we're in trouble.
But I digress...
If fleetfilter is selling the wik for $20 and napa sells them for $46 online, what is the difference between the filters? The napa site called it a "gold" / industrial. Then below they had it as just gold. Both for $45+ each. fleet had the 46637 (on the home page) for $19.00.
Not to highjack the thread, I'm just wondering from those of you that know a lot more about all this than I do.

Thanks, JT. I thought maybe there was a difference in filters. I was a little nervous that I may have gotten the wrong thing.
Now I'll have to dig up a little chunk of 4" pipe.

With that said, there was some studies done a while back on the temperature differences for the 6637 filter and it was basically not much difference once you are underway.
IMO it's an optional job.

The only advantage I know of is it cuts down on the engine drone when you stick a box around the filter.

air filter mod
my truck came with the K&N filter. I've been reading posts about the 6637 mod (as well as others). I've seen one or two modifications for getting air to the filter. These were mods to the backside of the grill, like cutting away material to get almost a direct airflow to the filter. Do most people get air from whatever is in the engine compartment, or do they get it through the fender like mine?
Bought mine with a big hole right out through the fender well.

Most people have the front of the radiator crawl cut out, so yours is different. Also get the K&N off the truck fast, those filters have been known to dust the turbo, plus they don't flow as much air as the 6637.
