  • NGK Spark plugs for 2010 Mazda 3i
The old NGK spark plugs that I replaced on my 2010 Mazda 3i still looked quite good compared to the new ones. This means that these spark plugs can last for more miles. They are inexpensive and easy to replace and perform well. These fit the 2010 Mazda3i and are recommended.
