🔌 Champion Copper Plus 439 Spark Plug: High-Performance Pack of 4 Review

Good product, pre-gap, easy to install. Dakota 2006 4.7L Time will tell how durable they are, they have only been used for a few months. So far, so good.

About a month ago I installed eight of these in my 2000 Jeep Grand Cherokee Laredo 4.7L. Works perfectly. I'm glad I bought them. The delivery was quick too.

orgers mentioned it and it's still wrong. The original ad says "4 boxes". I need 8 plugs. So I ordered 2 boxes. Instead of 8 ports I got 2 ports. Please correct your ad. I now had to buy 6 extra plugs. So make sure you order plugs and not 4 in a box!

Bought these for my 2004 Dodge Ram 1500 4.7 V8 that uses the same plugs. The truck gave me the cylinder misfire code, and it was tuning time anyway. I decided to change the spark plugs along with the ignition coils, so I bought these. They came with a .040" gap (spec for this engine) and I checked with a gap tool. In the picture you can see one of the old spark plugs (original for the engine) on the left and the new one on the right. So far the truck works without it Codes flawless and even…

I don't know what the first picture in the ad has to do with anything (attached), decided not to order it, because I wasn't sure the picture or description was wrong. Don't pay attention to the picture. These are the correct plugs for the stock 4.7L Grand Cherokee engine and the price was cheaper than I could buy locally. If you have a 4.7 liter HO engine, this is NOT the correct connector. The high output version requires the following: https://smile.amazon.com/gp/product/B002VVKHKE/ref=ppx_yo_…

I bought these for scheduled maintenance in my 2004 Dodge 4.7l. These motors really do prefer copper connectors and so should you. Don't believe the ads for insanely expensive candles. Other metals last longer than copper but generate more heat and less power. Especially with these connectors, Champion seems to be the standard among copper connectors. I never trust pre-gap plugs, but after testing they all came to an average gap of 0.042. None of them failed. After a few hundred kilometers it…

Bought these for my 2001 Dakota 4.7L as they are recommended by Dodge. Why use spark plugs other than those specified by the manufacturer for this engine? Done, use the recommended forks! I took this truck used, the previous owner changed the oil but didn't change the spark plugs. Along with the candles, it also replaces the KS, and it purrs like a kitten idling with very good acceleration on the highway. Check the gaps, one of the plugs has not closed properly and use a torque wrench to make…

They arrived well packaged and in their original boxes. I replaced my old spark plugs with a 2nd generation Durango with a 4.7 liter V8. I checked them all before installing. Even though they are pre-approved, some of mine weren't up to spec. So do yourself a favor and prepare the gap and adjust accordingly. For installation I have included a picture using dielectric grease and copper based anti-seize grease. I only apply a minimal amount of anti-seize to some of the center threads on the…
