Review on ⚡️ Enhance Engine Performance with Motorcraft SP-500 Spark Plug by Kenneth Broszko

These are genuine Motorcraft Platinum circuit boards. They work great in my 2005 4.0L V6 Explorer. Some motors require the SP-400 and I believe the SP-500 connector is the same just platinum. My old spark plugs were worn out and had a very large gap, so installing them caused me a lot of power loss and eliminated the rough idle. Use anti-seize and dielectric grease for smooth operation. You must install them yourself before the specified interval. Be very careful when splitting platinum connectors, make sure your splitting tool is round and has a hole ($1 at any parts store) that will allow you to pry off the ground electrode without touching the platinum tab underneath. The platinum center electrode is very thin and brittle and will break if a force is applied to it.
