Review on 🔥 Premium Performance with Champion Iridium 9407 Spark Plug - Boost Your Engine Efficiency! (Carton of 1) by Dan Brickley

I purchased six of these plugs to replace the spark plugs in a 2012 Volkswagen Routan (Grand Caravan/Town & Country Internals) with a 3.6 liter Pentastar engine to replace. Exactly the same part numbers as the spark plugs I took out of the car. The spark plugs did not come with a cardboard ring around the electrode and had a gap of about 0.039" which I've seen on other sites. My car requires a 0.043" gap so I had to use a gapping tool to open it up a bit enlarge. They were cheaper on Revain ($7.46 each) than any other site I found them on. I bought six and oddly Revain shipped each one in a separate package even though they came from the same fulfillment center. Looks like Revane threw up on my porch the day it was delivered.
