It looks like Wix #51045 is the largest/tallest filter for our trucks. 4.8" vs. K&N's 4.5". Whether than translates to better filtering or more filtering media, one can only cut it open and test it. I'm sure all 3 are good filters, but I want to see what everyone was using.

I saved this from another site. I cannot attest to the accuracy of the information or the knowledge of the person who provided it...

The 07 Classics as well as the NBS 07 Silverados( all V8 engines = 4.8L, 5.3L, and 6.0L )all take that new filter. It is not the same as the earlier filters and will not fit as you discovered. While the overall size is the same the new filter uses metric threads( 22X1.5 MM ). The old ones used SAE threads( 13/16-16 ). Many parts stores do not even have the application listings yet or if they do show it they don't stock them yet. Filter was 1st used in 06 on the Z06 Vette( possibly others? )and is now used on most 07 vehiles
The previous filters were the long PF61( 02 and earlier )and the short PF46( 03-06 )for the Silverado V8's. The PF46 is the same basic filter as the PF61 just shorter( approx 3.5" tall )with a higher burst rating and slightly better filtration rate. The PF46 filter runs through 06 for the V8 Silverados. The PF46 and PF61 are interchangeable room permitting.
The new filter used starting wiith 07 Classics on the V8 trucks is a PF48. It is the same approx size as the PF46. I do not know if there is a long version of this filter? I do not believe there is though as this filter is used everywhere including the Vette. There just is no new long filter that I know of that has the proper spec's and metric thread?
Car mfg's are trying to stream line and make fewer filters so this one is being used a LOT. They are dropping the PF46 because they now have this new one( PF48 - of course why not just keep using the PF46 as it is the exact same size ). You would have to check stats( ie; thread, seal diameter, burst pressure, etc... )and see if you could find a long one. All the 07 V8 "gas" Silverado's( 1/2 tons & HD's and 4.8L/5.3L/6.0L )take this filter.
Here is a list of the part #'s for the new filter that I can find( FYI - not all mfg's even have it yet ). Obviously it is not all of them. Just the ones I know of at this time...

AC - PF48
K&N - HP-1017
Mobil1 - M1-113*
Wix - 57060
Napa Gold - 7060( relabeled Wix )
Baldwin - B160
Hastings - LF613
Purolator Premium Plus - L12222
Purolator Pure One - PL12222
Fram - PH10060**
STP - S10060**
Champ - PH48
SuperTech(Wal-Mart) - ST10060**
Penzoil - PZ167**
Carquest - 84060

* - the Mobil 1 site does not show a filter for this application/equivelant to PF48. I found this filter being shown by application on another site and when entered at various filter sites it does cross to the PF48 filter line for that mfg.

Wix has been supplying us (CARQUEST) since the mid 80s or even before. They build an excellent product and supply us with both our Premium (Blue Line) as well as our Economy (Red Line).

I have been in the auto parts industry for 29 years and have sold AC Delco, Hastings and Wix, all good filters. In all the training classes and seminars I have been associated with, it comes down to this. Filtering vs flow. A filter can be made to filter out almost anything including the oil that is supposed to be passing through it. There is a fine line to making a filter that flows as the OE specifies and also catches the dirt. You will also see that some filters do well when first installed but they have not dirt holding capacity and they do not test well after a few thousand miles.

I have nothing against K & N, Mobil or others (well except Fram) but I believe that Wix does a great job in building a filter that flows as required but still traps the dirt. Even their economy line filter is a great filter and uses the same quality construction as the premium filter but the filter media is not the same. My only comment on AC Delco is that they do not actually mfg their filters but contract them out. The actual mfg can change from year to year as the contracts change. However, these mfgs have to meet AC's specs and I have seen many filters cut open and the AC's always appear to be of good quality.

I will add, all filters with the exception of the newer extended drain filters are done for after 5K to 6K miles. If you are running extended drain intervals, you need to be changing the filter at least by 6K.

You get what you pay for....Have owned & maintained commercial vehicles and have seen "Brand F" come apart on some smaller vehicles. With $15K+ tied up in an engine, cheap filters don't pay. Will only use WIX or Hastings (Carquest or NAPA). One should have the same attitude with a $30K truck.

I recently changed to Wix, sounds like a good product. I will have to admit that fram sure is/was tempting at the Walmart especially the ones with the "bed-liner" material applied for extra grip. I guess they have a patent on that or something, I wish other make would do it as well.

Fleetgaurd as well as Baldwin are both offer very high quality products. The problem is they are not readily available to most people unless they are willing to locate a Heavy Duty Truck supplier. We run into them all the time in fleets and nobody can take anything away from their quality.

Working in the marine industry, we use Wix oil filters and never had a problem. Since I have had the truck, it has only seen one filter: Wix.

I was buying the K&N Oil Filter until I actually learned more about it. If you read the box the k&n oil filter only catches about 90% of impurities. Now I know thats nothing to worry you about much because they are made for racing but when it comes down to protecting your engine I want a filter that protects my engine more than any other brand.. I think Mobil 1 is like 92-95% Efficient I really cant remember what it was exactly but it was suprisingly better than k&n and like $4 dollars cheaper at least from Auto zone....
