## Questions & Answers

**Q: I have a 2002 Toyota camry 4cylender what is best spark plugs should I use**
A: This spark plug I thought would be great for my 2004 toyota RAV4 and I have no reason to think otherwise after 1,000's of miles and about 2 years of use.

**Q: My car calls for ifr6a11, but these are ifr6t11. does that one letter matter? it says here that they fit my car.**
A: As best I can tell from the NGK site, the IFR6T11 is the new number for the same plug. NGK says it does fit my 2006 Camry 4 cylinder.  However, there is a SIFR6A11 in the NGK site at a much higher cost.  A warning comes up that it does NOT fit my vehicle.

**Q: Is this just a single spark plug ? or a set of 4 spark plugs?**
A: Come in single one , I bought 8 for my sequoie

**Q: Do i need to use anti-seize on these spark plugs?**
A: From what I read, you should always use anti-seize. I did and the little bit of money that it cost gives me a better piece of mind.
