Does its Job Well!
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!

The Highest Quality Genuine Spark Plug
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.
