## Description

Laser Iridium spark plugs provide superior ignitability and long service life. Smallest tip diameter available Iridium / Platinum surfaces ensure slow wear rate providing stable idle, superior anti corrosion, improved fuel efficiency and lower emissions. Laser welded Iridium center electrode tip ensures high durability and greater spark. Platinum disc welded to backside of ground electrode provides long life. Longer insulator nose prevents carbonization, Corrugated ribs on insulator prevents flashover, and the triple gasket seal eliminates combustion gas leakage. Faster starts and quicker acceleration. Better fuel economy and lower emissions, Trivalent Metal Plating for superior anti-corrosion and anti-seizing.

Review: Genuine NGK Part - They are genuine NGK spark plugs. I verified this by contacting customer support on the NGK website. They were very responsive and polite. The product arrived at my door in a soft envelope, so the individual boxes that each spark plug comes in were a bit squished. No apparent damage to the plugs and the firing end is protected with a stiff cardboard ring. NGK did comment in the email reply "Please do not use anti-seize or lubricant on NGK spark plugs and torque them to specifications." I believe this is due to the nickle plating on the threads.
Review: Just installed. Seem like good quality - Just installed them today. Car is running better. Not sure about Longevity yet but from what I’ve read NGK are good ones. Only thing that upset me was how they were shipped. They were shipped individually in a box with 5qts of oil and a heavy oil filter. When I opened the box 3 of the 6 spark plugs were out of their individual boxes rolling around free.

## 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.
