## Questions & Answers

**Q: If I get this item Do I need fp3?**
A: If you have a good free flow exhaust and this k&n setup I recommend having one so you don't risk leaning out your bike. Otherwise if all you do is change the filter and housing then, no.

**Q: Does this affect riding leg position?**
A: Yes and no. My leg rests up against it while I ride vs the stock one. But you don’t even notice it. That’s on a 05 Electra glide.

**Q: Is there a rain sock for it?**
A: No K&N does not make a rain sock for this intake.

**Q: will this fit 05 electra glide?**
A: Yes for sure it will
