Reliable performance and a noticeable engine boost
I recently swapped my old plugs for this 4-pack of NGK Iridium IX ones, and the difference was clear right from the first start. The engine definitely feels like it’s idling smoother, and I’ve noticed a much more responsive "snap" when accelerating. NGK is usually my go-to for ignition parts, and these Iridium plugs live up to the reputation—they handle high heat incredibly well and provide a very consistent spark. If you’re looking for a simple way to restore some lost power or just want to keep your ignition system in top shape, these are worth every penny. Pros: Improved Ignition: Faster, more reliable starts and a smoother idle. High Durability: The Iridium tip is built to last much longer than standard copper or platinum plugs. Better Response: Noticeable improvement in throttle response and overall engine efficiency. Cons: Price: They are a bit more expensive than basic plugs, but the longevity and performance gains make them a much better long-term value.

Great plugs, fit my 19 Kia soul 2.0 and fixed my rough idle
Had new autolite iridium’s in my 19 Kia soul with 2.0. Should have known better. Bought these NGK’s and instantly got a better idle. Just buy the best and be done with it. Half the price of local part stores.
