NGK Iridium IX
Ordered these plugs for my 18 ram 1500 5.7l. Installed these plugs at 100k miles. Definitely see a better throttle response and truck idles better than before. Driving feels better and not sluggish as the old plugs. Definitely worth the money!

Great deal, better than I could find anywhere else.
Plugs are exactly as listed. Changed my plugs on my 2018 Ram Hemi. Fit was perfect, performance improvement was about a 7% increase in MPG, but expected that to happen as I changed my plugs at 82,000 miles. Delivered quickly as I ordered a day prior to wanting to change them. Arrived as expected, no issues or problems.

Confirmed fitment for 2014 RAM 1500
Great product - nice fit and lasts a genuine 100,000 miles… which for a RAM 1500 owner is a joyous feature (as changing all 16 can be a nightmare that you wouldn’t want to be doing any more frequently).

Great price on great spark plugs.
Iridium plugs recommended for ram 5.7 l motor. 2019 ram bighorn needs 16 plugs. They were all pre gapped perfectly.

Not gapped but good product
They came not gapped so I had to do that myself but overall definitely happy with it. And will buy again. Bought it for my 2014 Ram 1500 5.7 Hemi.

Great Upgrade and Excellent Product
My engine was starting to have a sluggish throttle response, poor acceleration, and gas mileage was sucking worse than normal on a 5.7 Hemi. These plugs were an upgrade from the garbage stock plugs the manufacturer originally installed. They were all gapped perfectly and needed no adjusting. They were individually packaged with protective plastic covers around the threads and electrodes to ensure they were not damaged. They immediately boosted performance, including better throttle response and smoother engine idle. For full disclosure, I also replaced the stock ignition coils with NGK coils. Hopefully, the plugs last and don't have any issues.

Just what I needed.
Plugs were pre-gapped and exactly as described. Cheaper than the local auto parts chain store and MUCH cheaper than the dealer.
