## Questions & Answers

**Q: What is the flange OD to properly size a T-bolt clamp?**
A: A 3 inch clamp works fine.

**Q: Is the filter really pre oiled or should i buy the oil sepetately?**
A: I ordered 2 and mine were pre-oiled. Since i live in a desert, lots of dust, i applied 1 thin layer of oil just to be shure its lubricated properly, catches more dirt. I also wouldn't hesitate to buy the k@n cleaning kit with oil, as you gonna need it anyway.

**Q: Will this fit a seadoo rotax engine? It uses a 3 inch filter**
A: This filter will fit onto the 3" intake tube. However you may run into issues with filter clearance. Please reference the picture with all filter dimension and verify the filter will have proper clearance.

**Q: where  is the measurement where filter attaches ?**
A: The K&N RU-5111 Universal Clamp-On Air Filter has a flange inside diameter of 3 in or 76 mm.
