When my Y2K GMC with the 6.0 V8 was new, the recommended Delco oil filter was a PF-59. Sometime around 2005 or 2006, that model was discontinued and replaced with the PF-46, which was only about 2/3rds the length of the PF-59...at no reduction in price. I quit using the Delco filters and began using either K&N or Mobil 1.
I beleive i am correct in this but may not be, i dont claim to be a filter guru. But due to working in a parts store and a shop for breif periods as well as doing maintence on a good range of vehicles over the last 10 years...im pretty sure those filters your talking about cross over to the purolator 14459?
But did you expect price to change? That pf46 is ususlly the same price or within 10 cents of that big ford filter which is ph8a in fram for fl1 in motorcraft.
