NGK Spark Plugs (USA),Inc. IZFR6K11 Spark Plugs Izfr6K11 4Pack

This is a direct replacement for my 2004 Acura TSX. The fit and finish exactly matches the original spark plugs. My car has 96k miles so the owner's manual called for new plugs. Besides, the center electrodes showed signs of mild pitting and wear. That is expected after 12 years of daily commuting. The removal and replacement took 30-40 minutes. Gaps were identical to factory specs and I did not need to make adjustments. The 2.4liter Acura/Honda heads are aluminum so I do not recommend working on a hot engine as you may strip the threads. An extension rod is needed to reach down into the valve covers. My car starts a tad more quickly and idle is stable. I have not noticed a considerable gain in horsepower or fuel mileage but I suspect that this is because of the quality fuel and regular oil changes - my engine is in excellent condition with good power and no oil consumption. My old plugs looked worn but came out very clean. No oil and almost no carbon build up. As an FYI, Denso makes a comparable product but NGK is recommended by the manufacturer and since the original set worked for so well for so many years, I see no reason to change brands. It is a solid choice for routine maintenance and doing it yourself will save you a bundle. Thank you NGK.

Several recent reviews are stating that these plugs are FAKES, but they don't give any specifics on what makes them "fake". I purchased mine via "sold by Overstock Direct" and "shipped by Amazon". I can confirm via the many YouTube videos on how to spot "fake NGK plugs", that the ones shipped to me are authentic NGK. For example, the plugs I got have the production white powder on the plugs, light blue lettering on the plugs, plastic cap to protect the plug and base threads, box is white and see-through, orange hazard symbol on box, colors on box are correct, etc.) Possibly not all sellers are shipping authentic plugs, but don't say ALL PLUGS ARE FAKE...give details so potential buyers can make informed decisions. Lastly, NGK does not recommend using any kind of anti-seize on the threads. These plugs are for a 2006 CR-V, and are OEM plugs for this vehicle. Highly recommended and great price.

These were exactly as described, OEM NGK for 2008 Honda CRV LX coming up to the 200k miles mark and needing new plugs. These were in pristine condition, included the spark plug screw thread and gap protector sleeve. I double checked the gapping just to confirm if they were 0.044”, which they were. Remember to put anti seize on the threads to facilitate removal on the next 100k miles. My old plugs which were also NGK same part number looked pretty work and had some burnt parts near the crush washer of each plug. I guess that’s a sign of high temp burning the aluminum crush washers. I may consider replacing spark plugs at 50k miles next time just to be safe.

Needed these for a 2007 Honda CR-V. Much cheaper than anything you can buy from the dealership, and these are OEM replacements. Gapped correctly right out of the box. All you have to do is plug em in and you're off. Engine starts and runs smoother now with these plugs. They're not super well packed, but there is a thick plastic sleeve deal on the electrode side of the plug to protect it in shipment.Will definitely buy again when/if needed.

Quality NGK spark plugs, box came wrapped in black privacy film. Product lot number stamped on side of plug as well as NGK website labeled under the country of origin, Japan. See through plastic thread protection on each plug. The counterfeit plugs that are making the rounds do not have correct lot numbers. Plenty of real vs fake videos on youtube showing how to tell the difference.

The usual NGK high quality. Be careful of the gap - in my case, one sparkplug of four wasat a much smaller gap of .040. Be very careful when adjusting the gap (use the proper tool)and do not contact the center electrode. Work fine in the engine. Smooth running restoredafter over 60,000 miles on the previous pair.

Replaced the original ngk 6994 in my 2006 Acura TSX after 17 years and 143k miles. To their credit, the car still started and ran fine lol. These things are built to last. And these are the real ones with a stamped number and all the other signs of being legit.

I replaced my old NEG plugs that had 10050 k on them, my 2007 CRV has pep again just like out of the show room
