Review on 🔥 Denso 4503 Spark Plug: Unmatched Performance and Reliability by Loren Slama

I ordered this to fix my 2011 Dodge Caliber, car stuttered for a while while driving. Initially I assumed it was a transmission problem because the dealer I get my car oil change from for free said there was a transmission leak. After some research, I found out that old spark plugs are a common cause of stuttering. I ordered this and a spark plug boot for my ratchet and the job was done in less than ten minutes. Very easy to repair, connectors easily accessible and thanks to the spark plug connector with magnet I don't have to look for old connectors. The caliber now runs much better and absolutely stutter-free. Will update rating if product breaks unusually quickly.
