Review: Reliable and efficient - This fits perfectly and fixed the misfiring in my old Toyota. These are a huge upgrade over the previous copper spark plugs that last only 30k miles. These are great quality Iridium plugs that can last over 100k miles and I put around 45k miles with these on for the past few years and they are still going strong. My engine has way more power now and pulls more compared to before with my old plugs. I got the horses restored. Review: Nice Spark!!! - These plugs are awesome for the price. They fit perfect and deliver the spark needed to keep my 02 Lancer OZ Rally fired up and moving. These ended up being a fraction of the price of cheaper or no name comparable ones available. I have had no issues with and would not expect any problems either.
