NapaGold Oil Filter vs Napa ProSelect Oil Filter Comparison
Napa ProSelect uses a coil spring rather than a leaf spring; a coil spring keeps better pressure against the end cap. The ends of the coil should be bent inwards to prevent damage to the can.
Napa ProSelect uses metal end caps rather than the fiberboard end caps.
The filter media inside the Napa ProSelect was glued to itself, rather than crimped with a metal bracket.
Napa ProSelect uses a phenolic resin which helps to bind the media and protect during high temperatures.
The center tube of the Napa ProSelect filter is a spot-welded, straight seam; other brands use a spiraled center tube for better flow.
The Napa ProSelect filter uses a rubber anti-drain back valve. The anti-drain back valve is used to prevent oil from draining back to the crankcase after shutdown. A silicone valve is less likely to break down during high heat than the nitrile rubber.
NOTES:
The Napa ProSelect has fewer pleats than the NapaGold – 51 to 58.
Proselect uses rubber anti drain backs vs gold with its silicone
proselct uses single weld centre tube vs gold with its single spiral .
Found this info. Maybe it will stop all the questions? Link not working but googling Napa pro select vs gold difference its the 1st link.
