## Questions & Answers

A: I would say no. It fits the c15 a bigger engine that’s in tractor trailers. Try to get number off current filter

**Q: Not a question. Same thread but too wide for Powerstroke without pan modification. (?)**
A: Correct.  This filter is not meant for a Powerstroke.

**Q: What are the best oil, pre and secondary fuel filters for a 1999 cat 3126, 7.2l in a fl-70 freightliner?**
A: Amzoil has one of the best oil filters and oil filtration systems out there. They remove particles down to 3 microns

**Q: is it good?**
A: Yes, very. Caterpillar makes their own filters and they are very good. I highly recommend them.
