Ecogard x111. Came off a 2001 Buick Lasabre with 10k on the oil and filter. Replaces it with a purolator PL1011 red can and Coastal 10w30 Synblend. Was surprised to see it had fiber end caps. Looks decently made and did the job. The adbv was very stiff but i think these engine have a internal adbv?
