Review on 🔌 Denso 4702 IK20TT Iridium Twin Tip Spark Plug, 1-Pack by Scott Reid

Great Results. This was my first experience with this particular spark plug and I was keen to get a suitable replacement for the Bosch +4 that the car originally came with. Which I've never been a fan of, and I'm also unimpressed by the NGKs that most people use due to other car issues. Double check the game and of course always swap coils. I'm happy to say that my machine is running great. It feels a little smoother and my power and mileage are back where they should be. No problems with the scanner and all monitors are exactly where they should be. I wasn't expecting any problems so I'm really not surprised. I expect these Densos to last longer than the OEMs they replaced. I might change this depending on long term work. A little background, I'm an ASE double champion and they drove in a 1999 BMW 540i.
