Genuine 4 pack NGK Laser Iridium 4589 Spark Plug

Review: . - Todo bien
Review: Great product - These plugs are a perfect fit for my 2007 Toyota Camry and very easy to install. I do recommend using a magnetic spark plug socket with an extension. I tried using a socket with the rubber piece inside, but it would not let go of the spark plug.
