The Extra Guard still uses cardboard endcaps, a nitrile ADBV, and a cheap canister. They've improved the filter media, I believe, but the construction is still far below industry standard.
As I said earlier, their other lines are better.
To the best of my knowledge, the Delco filters on the market now are Champion E-Cores. They're better than the orange can of death, but not up to the level of Wix/Purolator IMO.
