Huge difference!
I bought a Pontiac Vibe 2005 recently. I have been having issues with a rough idel and un-burned gas smell in my exhaust. I bought these spark plugs and they fit perfectly. Great value for the money. You can see my old plugs. I don't know how many miles are on them. I just hit 250,000 miles on my vibe. It purs like a kitten now!

Good value, will not last as long as the platinum.
These lasted about 70,000 miles in our Chrysler crossfire. The gap was .40 when installed in 2019 and greater than .70 when removed in 2025. Because it is a Mercedes m112 engine, it requires 2 plugs for each cylinder. I will use the platinum in the future over iridium because they last longer. I did have two of the factory NGK plugs and they read a gap of about .44.

Great quality from a great brand. These I have used many times and never an issue. They come properly sized and they have proven to be long lasting at a very good price point

Changed spark plugs on 2008 Mazda3 1.6 with this set of 4 spark plugs. Works very well and no more stuttering engine during idle. Highly recommended!

NGK (5464-4PK) Iridium IX Spark Plug. I installed these spark plugs in my old 2007 model Santro Xing XO car on October 20, 2025. I waited this long to give my review after using them for the past two months. The main things I noticed are that my car's pickup has improved significantly, feeling like a new car again. The car's mileage has also increased to 15 kilometers per liter. According to NGK, these spark plugs don't need to be replaced for up to 50,000 kilometers. Another important thing I noticed is that the CO levels in the car's emissions have decreased. This means it's not only good for the environment but also increases my car engine's lifespan. I also understand that this provides a solution to the problems faced by older cars due to E20 petrol. Although the price is a bit high, considering the long-term benefits, I think paying this price is justified. Therefore, this investment is necessary to improve car performance.
