## Questions & Answers

**Q: Will it fit a 2003 Suzuki Burgman 400?**
A: I have same unit.  It fits fine. Don’t forget to unscrew little cap on top of spark plug. WIRE ONLY FITS WHEN YOU UNSCREW THIS CAP AND THROW THAT AWAY. I love it when a girl swallows all the stuff.

**Q: how many come in the box or is it 5$ a piece?**
A: 5 per piece

**Q: E3 website, autozone, and advance auto parts tell me the e3.38 is the correct plug for a 2004 yamaha r6. why does amazon say it's not?**
A: Go on E3’s website, you can check your original plug with their replacement. That’s what I did to get the correct one.

**Q: Will this spark plug work on my Tohatsu 50hp outboard motor. It's fully blue printed and i've been racing inflatble boats?**
A: I put these plugs in my Victory motorcycle, and almost immediately replaced them. It ran considerably worse with them, which was a bit shocking.

I can't recommend them at all.
