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.

Nowhere does it say pre gapped. "Facepalm"** A: I received my NGK plugs with a .042 gap. My Toyota Corolla Owners manual say's .043 for a gap setting. Advance AutoParts.com has post for this plug a gap setting of .044. Since the settings were not correct and technically the plugs should have came with the correct gap Amazon made good on the purchase. So now I need to possibly reorder. Ebay has these plugs, 4 for 14.99. Maybe that's why. **Q: Do these plugs fit 2006 subaru legacy 2.5 i limited sohc...** A: Yes, these are the right plugs for your '06 Subaru Legacy 2.5i Limited. In fact, not only are they the right plugs, but they are also the left plugs, so get a set of them. **Q: What is the gap on these? Do they need to be adjusted depending in the car?** A: Gap is I believe 043" (1.1mm). I have a 1994 Mazda Miata, and I did not need to gap these. You should check the requirements for your vehicle though if it's different. Also, you don't need to use anti-seize on the threads. These plugs are great! **Q: Will this plug fit my toyota yaris 2010 hatchback?** A: According to the information provided, this is the correct spark plug. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Highest Quality Genuine Spark Plug *by T***A on 11 December 2025* NGK (5464-4PK) Iridium IX Spark Plug.
