## Questions & Answers

**Q: This is a replacement for my john deere snow blower - model 1330se.  is there a gap requirement on this plug specific to my application?**
A: Good Morning! There is no gap specifically for your application. The 3924 plug was engineered to perform at a specific gap setting. What this means is that if John Deere says that the 3924 will match up to your OEM application it means that your snow blower was designed, engineered, and built to run with a plug at that gap setting.  I hope you have a great weekend.

**Q: how many is there ? for 4.71? 4 or one piece ?**
A: Per single piece

**Q: Do these come calibrated already?**
A: If you mean spaced, as in the spacing of the electrode on the tip, maybe.  Different engines require different spacing based on the requirements as designed by the mfg.  Always check the specs and space accordingly.  You may find the spacing correct as delivered, but that would be a fluke.

**Q: How many spark plugs Do you get for$5.66**
A: They come in 4
