I'll try to clarify this. Its not the coil spring in itself I would make the decision for, but the fact of whether or not they are using a higher cost component to make a superior product. If using the coil spring actually aleviates a real problem ( even if it is only a problem in 1% of applications or 1% of useful life ) then I would use Wix filters because they are spending the money to make a good product - AND - not trying to find ways to make an acceptable product at lower cost. Not an easy distinction for a lot of people to make, but for my purposes I want to buy products from companies that are dedicated to making good products and not dedicated to making more money on products that simply just work or work good enough to sell.
You mention KN, Mobil, royal purple and Bosch dp.. All filters I won't use. The most I have ever spent for an oil filter was $6 for a pure one. I have cut open a few Mobil 1, and I can't figure out why people pay $10 for an oil filter, there ain't nothing special about them, well maybe it has a thick can, but I don't see how that is a beneift. Which is kinda like my question, does the coil spring matter? Does it provide a real benefit?
In its simplest form it boils down to this, if Wix is going to spend the money for coil spring, then they will also spend the money for other little extras that make the filter a quality product. So I am trying to quantify if the coil spring makes it a quality product or if it is a marketing ploy at a minimal cost to - lets say - tv commercials, print ads, racing sponsorships, rebates, promotional products, etc....
Possibly WIX could spend a little extra on a 'quality' media....like PureOne and Bosch and Mobil 1....After all, 99.9% of the time the coil spring will never activate (if you change the filter at reasonable intervals)...but its the media that really counts in keeping your oil as clean as possible.
