Review on 🔌 NGK (7783) RC-TE65 Spark Plug Wire Set - Premium Performance and Reliable Ignition by Dustin Keller

I've had the infamous P0420 on my Avalon 98 for years. I've tried so many things, repaired the exhaust port, replaced the O2 sensor twice, replaced the valve cover, spark plugs (iridium), cleaned with sea foam . Nothing works. Then I saw this as an app suggestion after I bought a spark plug and thought I might give it a try. With the price, you lose an hour or two for a replacement. I did that and the gas tank went through with no problems. The sensor rotates normally, it is ready for testing, there are no codes, gas mileage improves from 100 to 130 km per half tank. Couldn't be happier! I figured I might have to live with P0420 for the rest of my car life. It's not true anymore.
