Noticeable gains. A good buy no issues
No issues after over eight months of pretty hard driving(dead of winter to 90+ degree heat and 50-60% spirited driving when I do drive. I will tell you this it is IMPERATIVE that you let your hemi engine warm up always at least least a few minutes preferably at least five before driving especially if you're putting high performance parts like these and others on your engine. Use common sense make sure you use the dielectric grease to encourage a good spark and I also replaced the plugs with the Lazer iridiums and used anti seize on the plugs

Still going
I bought these in 2017, and even though they lost the decal stickers on em a short time after, heat, engine wash etc, they are still going strong, they have paid for themselves by now, I still use them even now with nitrous.

Went from 14 to 19 highway mileage
Love the power and mileage this has given my 5.7 Hemi. Smoother idle, less engine whine. I fell in love with my truck all over again. The yellow caps are great, gives the engine bay more depth and they’re eye catching. As for the install, you have to actually know what you’re doing. Tip: add a small dabble of dielectric grease in the end of the coil holes before installing.2006 Ram 1500 5.7 quadcab

You prob should have already bought these
07 grand cherokee5.7lInstalled at 105k miles. Drastic improvement. Lower engine whine, increased MPG, increased power. Felt like it took 40k+ miles off the motor.New plugs were done at 100k, but these coils were just as important. You can actually widen your gap once these coils are installed, but i didnt bother because i dont want the combustion running hotter.Would have given 6 stars if they came in green.

Not worth the money if it rust after 35k miles
After 35k miles I go to change my spark plugs and pull the coil off the rubber boots pulled off. So I go to put the boot back on and just so happen to look inside the hole where the spring goes and every screw that ignites the spark plug is rusted.

Recomended if you got the money
You can find cheaper but you wont find better.OEM is cheaper but these have solved many issues I was having. The extra percentage of spark is actually greater then 10%. It turns these solid copper plugs into a quality you would find in iridium plugs.

Made a noticeable difference in vehicle
I was amazed at how much of a difference these made. Mainly in the takeoff. It also seems like I am getting a little better gas mileage. I would purchase again. Have had installed for 2 months.
