Review on 🔥 Enhance Performance with Denso 3444 Spark Plug for Optimal Ignition by Will Schimmel

I bought these iridium spark plugs for my 2011 Prius. It's an exact replacement, much cheaper than the dealer wanted. I can count on it for the next 100,000 miles. After installing the new kit, the car picks up speed 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, it takes a 14mm deep socket and a long extension to get the old spark plugs out, almost 2 hours start to have in my garage I'm looking for a video with instructions on YouTube. 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!
