Worth going for the Napa Platinum since it's on sale this month. But out of the cheap filters, I'd easily take a Supertech over a Purolator; the ST is made by Wix now.

It's on sale this month for $7.50, making it cheaper than both Gold and Ultra
Between Purolator and Supertech, I would run the Supertech as well. Purolator seems to lack quality control. I don't trust them. I like Wix and ACDelco for my 5.3, but anything goes on my other engine. Even a Purolator if the price is right. I have a NAPA silver for the 2.2 next OC. On sale for $2.50 last month.
