Great spark plug!
I have run several different types of spark plugs in all types of vehicles and trucks (350Z modified for racing, Nissan pickup, Corolla, etc.). I replaced the OEM Toyota plugs in my Tacoma 6 cylender truck with these and the vehicle runs great. I took a long haul trip camping with a full load the they ran smooth and did not act up at higher temperatures. Great replacement plug - a bit more in cost but woth the few extra bucks. Pre-gapped and ready to install. Recommend using anti-seize for the threads to ensure easy removal and prevent damage in future. Shipped and packed well.

Good sparkplug
Car ran smoother after install. Also changed out coils at the same time.

Great plug - good performance, gas mileage - just be careful gapping
Plug works great in our turbocharged volvo. Good gas mileage, good performance. Can't speak to durability yet - but no reason not to expect good things. Performance is great - and we were able to take a slightly longer gap with and have it still work great. One thing - you have to have the right tool to gap this (without bothering the electrode) and even then exercise caution - because fairly minimal disruption can destroy it. Given the sensitivity, I'd really prefer if they sold these pre-gapped, like Bosch did with the +4 platinum plugs.

One starr off for packaging
They are spark plugs. You may need to carefully regap them to the appropriate size. They look to be high quality and are a reasonable price. One star off due to the packaging by Amazon. Several of the plugs had come out of their individual boxes and were rattling around in the main packing box. Fortunately, they appeared to be fine and un-bent.

Best deal on the web and spark plugs are working great. I'm a real person, no robot!
My 2008 Lexus ES 350 now sounds amazing by purring like a kitty! The price for these at Amazon is such a good deal. NGK Iridium are the best for Japanese Luxury brands in my opinion. My car is running is much better!

Best in the business
There is no need to write a long essay about these spark plugs. They are the BEST in the business, and that's that. Once you put them in your car, it will feel like your car just became supercharged, since you've never had the full power intended - with crappier spark plugs. This unleashes the car's potential. I have them on my BMW x5 and for the first time - at 70,000 miles - I feel like I have a new car....

Just have the right tools to replace these plugs
3 back Plugs and 3 front replaced with new coils.Ater 3 hours of sweat, wine and blood, I saved 600 hundred dollars buying parts on Amazon not including the 500 in labor saved because I did this myself. 1100 saved!The old plugs were 9 years old, real dirty and burned.A big difference in performance and runs alot smoother. I like these NGK Definitely will buy again!

Wish they came in a set of 8
I bought these to replace the same ones I installed in a toyota with a 5.7 V8. I put 87,000 miles on the last set and they probably could have gone much longer--although wear depends on a lot of other things such as maintenance and driving style. The big V8 purrs. I read that other toyota 5.7s can clatter and sound like a diesel, but after that first change to NGK 6619 plugs and Royal Purple 5w-20, mine sounds great.
