Review on 🔥 Denso (4711) IXEH20TT Iridium TT Spark Plug: Enhanced Performance (Pack of 1) by Jimmy Bhat

Installed these spark plugs on my 2014 Mazda 6 with Skyactiv 2.5 engine at 74,000 miles. Denso is one of the brands I use for spark plugs as I have always had good service from them over the years. The candles appear to be of excellent quality and are well packaged with a plastic tube over the electrode area protecting the candle from damage in transit. With this motor, this is a breeze as it only requires a 14mm deep socket and magnetic pickup. Tool to remove the plug from the well if it is loose. Before installing, I smeared the threads with some anti-seize (probably not necessary, but it makes me feel more comfortable). I used a piece of fuel line on the connector to route the connector to the head and start the threading. Torqued to 13 pounds with a torque wrench, but can be adjusted using the "partial turn after hand tightening" method found online.
