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.

Placed order after checking fit but when installing discovered these are not mechanically the same as original and don’t fit the car.
