## Questions & Answers

**Q: What is the correct torque on these?**
A: Sorry I don't know,  but like with any spark plug,  just snug them down.   They aren't going anywhere

**Q: Are these plugs pre gaped?**
A: You must always check the gap on spark plug replacements against recommended gap for that specific plug. Even plugs that are pre-gapped can have discrepancies due to shipping and handling. 
- worked at a auto parts store for years

**Q: Will this fit perfect in my 2012 c250 coupe?**
A: Not sure but it fit perfectly in my s550 benz.

**Q: Do i have to game these? what to gap with? and what size socket is required?**
A: You do not have to gap them.  It is a 5/8 deep socket.

These pre-gapped plugs are great for your engine. It took me 1 hour to replace all my old plugs with these new ones in a V-8 Mercedes 550 engine. EASY. The NKG plugs are running smoothly and sometimes, as with these, small things can make a big difference. I had previously installed Bosch, but after 50,000 miles I felt they needed to be changed because I was seeing degradation in my fuel mileage. I will come back and update this review in 5,000 miles to tell you if and when my mileage has improved. I can already see a upgrade in engine performance just going about 10 miles.
