Below is photo of Mahle/Knecht oil filters from my Porsche 993. One on left is engine filter and one on right attaches to thermostat housing on oil tank. They seem to be well made. There have been on vehicle for 14 months but only 625 miles.
The OEM filters I purchased today at dealer are made in USA, I think they are Hastings; besides Porsche numbers one has LS 143 on it and the other has number LS 174. Are those numbers from manufacter?
