Review on 🔥 Enhance Performance with Denso 3444 Spark Plug for Optimal Ignition by Hugo Caywood

I bought these iridium spark plugs for my 2011 Prius, these are an exact replacement, much cheaper than the dealer asked for, I can count on them for the next 100,000 miles, my original set lasts over 103,000 miles - still runs fine, once the new kit installed the car is faster and much better, the powerband merges with the highway entrance so the iridium plugs REALLY degrade performance and fuel economy. I saved a few bucks by changing the spark plugs myself, it was a fist and labor intensive disassembly of the chassis parts to get access to the coils/spark plugs, takes a 14mm deep socket and a long extension to get the getting old spark plugs out, almost 2 hours start to finish in my garage, I search youtube for a how to video. You will need a torque wrench to get the correct 15 ft-lbs of torque. So.amazon rocks with free shipping and the best prices!
