I'm running Lazer iridium in a 3.6 grand Cherokee overland and I bought ruthenium ngk plugs for my 2011 cr-v, which are supposed to last longer than other types of ngk plugs.

I bought the recommended Denso Iridium from a local parts store I trust (and get a discount at ), so I guess the Iridium LKR7DIX-11S would be fine. However, the IZFR611 you mention is listed as a Laser Iridium and is one heat range hotter. Who knows?

Thanks for your reply. You mentioned that the Laser Iridium is one heat range hotter, what's the implication of that? Does that mean that it should last longer?

Also when you replaced your original plug, was it Denso SKJ20DR-M11 installed by Honda? Thanks!

Found this article written by a mechanic in Japan: Denso vs NGK – Which Spark Plug Is the Better Choice? (carfromjapan.com)

I found this diagram from RockAuto (never purchased anything from them before)..

More Information for NGK 93175

It seems that the Ruthenlum HX is the best? Thoughts?

- No, it just burns slightly hotter, so good if you just make short trips or if your engine is burning a bit of oil.

Also when you replaced your original plug, was it Denso SKJ20DR-M11 installed by Honda? Thanks!

- Sorry, not sure. They were original fitment from 2009, no reason to keep them.

Looks like you are correct. Are they expensive? I paid around 30 CAD each for the Densos.

These are rock auto usa screen shots for 2011 honda cr-v spark plugs, ruthenium almost a dollar cheaper than Lazer iridium.

I emailed NGK tech support about the "BEST" NGK plug for 3rd Gen V (especially for 2011), and this is the answer that I received:

"Thank you for your inquiry. ILZKR7B-11S is the actual OE plug, which is the best option for your vehicle for performance and service interval."

Just a quick FYI. Also, this article might offer some good info too. According to this article,
"Ruthenium is less expensive than Iridium, making it a more affordable option for some drivers.
However, Iridium is more corrosion-resistant than Ruthenium and has a higher melting point, making it a better choice for applications that require a high degree of heat resistance."

Many posts say Honda's use NGK or Denso plugs. Which specifically comes in the 2010 CRV? Has anyone tried the NGK Ruthenium plugs? I do not want to pull the plugs until I have the replacements on hand. Thanks

I installed ruthenium plugs in my 2013 CRV (179K miles) and so far, the car seems to be running very smooth.

Ruthenium or Lazer Iridium from NGK, Lazer Iridium being the higher tier plug, both good for 100,000+ miles, can be bought from Rock Auto.
