## Questions & Answers

**Q: What is the BMW part number and it is available to order at a dealership?**
A: It's "licensed" but not produced by BMW... a dealer would only have it if they purchased from an outside source. Made in China, BTW.

**Q: Beautiful kit.  but the wire that activates the piston lights is about two inches too short.  is there a remedy for this?**
A: Try different routings - I found one that just barely made it - plug the wire in first, then mount the motor on the base.  Alternately, cut the wire, solder in an extension as needed.

**Q: Is it pretty cool, It looks so badass ?**
A: Extremely cool. I have a collection of model engine kits and this one fits right in.

**Q: Box size**
A: The box dimensions are 21x14x7 inches. Cheers!
Kory
