DAY & NIGHT DIFFERENCE!! 09' Dodge Charger 5.7 Hemi V8
Amazing!!! These are great spark plugs!! Was having misfires and bad idle surge. Coil packs tested good so Decided to start with the cheapest part of the ignition system. Replaced all 16 spark plugs with these copper ones and oh my what a difference!! There's a steady idle now, rumbles nicely with the big cam and has no hesitation on take off and acceleration now. Went with Copper Spark Plugs because copper is a better conductor and will spark hotter then any other kind of plug. Copper may not last long but they are the way to go for performance, not those junk platinum ones. These will be the only plugs I buy from now on! BUY THEM!

Like night and day after install 5.7 hemi
Put these in my 2011 ram 1500 5.7 hemi at 50k and wow what a difference. If your dog the same you will need 16, plus some anti seize, some dielectric grease, a gapper, and i definitely recommend the magnetic socket. You are going to need to gap them all so grab a beer, ot takes a minute. I also too that opportunity to put the anti seize on the threads and put each one back in its box untill install. If you have a modern hemi stick with copper as the newer plugs can cause serious issues.

Decent economy plugs by a well known brand👍🏾
Decent set of plugs that won’t hurt your pocket. The best part is they’re manufactured by a respected brand. They’re name isn’t Champion for nothing 🫡

Good price, double check the gaps
Installed on 2011 Dodge Durango 5.7L. Pretty good price. Double check gaps on these because some of mine were off. I needed a 0.044 and some were only about 0.038. Otherwise great product, especially for the Hemi. It’s a picky motor about which spark plugs work the best.

Champion Plugs Installed in 5.7 Hemi
Installed these Champions (16) in my 2014 Jeep Grand Cherokee. I have 42K miles and had noticed my gas mileage dropping. Well that's because the plugs are supposed to be changed at 30K miles. This doesn't make sense to me because all newer vehicles go at least 75K miles- except this one. The change was easy and my Hemi runs smoothly. Fuel economy improved 2 MPG hwy. The Amazon price is fantastic and Champions are the only plugs still made in the U.S.A. Recommended!

Five Stars
Fits good. Just installed on my 2011 dodge ram 1500. What a difference after replacing old worn down plugs. Plugs ran smooth I but lost some power because I put these in the lower bank. I replaced the lower bank with Champion Iridium 9055 plugs and kept the Champion 446 Copper plus plugs in the upper bank. Truck runs great now

Every guy's favorite thing to replace in the truck
WOOOO!!!! spark Plugs. Every guy's favorite thing to replace in the truck! By a Dodge with a Hemi and you get to do 16 of them! These fit the truck, they make a hot spark and the truck runs good. what more can you say. just wish I didn't have to replace every 30k.

Deceiving
Don’t be fooled by the item description? Clearly states package of 4. Lie!! I ordered 4 and received 4 spark plugs! Literally. I have a 5.7 liter Hemi which requires 16 spark plugs. Judging by the description I ordered 4, which would be 4x4 equaling 16. Not true. Reached out to the seller and no response. Now I’m out 12 spark plugs and no tune up.
