Autolite Iridium XP Automotive Replacement Spark Plugs, XP6203 (4 Pack)

Great set of spark plugs

Fit my 2013 Hyundai Sonata 2.4L and seem to be working well. I noticed more power and quieter acceleration with these.

Good price

Put these in to replace some old spark plugs in a 2015 Optima that had 85k miles. Works with no issues.. my gas mileage seems to be slightly better though I may need to drive a little more to determine that. My engine seems to be a bit quieter when accelerating as well. Haven't noticed much difference in acceleration or anything like that. Smooth idle as well. Nothing else really to say

This is just what my 2015 Kia Rio needed.Perfect replacement, easy install, and little to no gaping needed
