Rated 4 out of 5 by from GOOD PLUGS These NGK spark plugs are factory recommended for my Hyundai Accent. I haven't noticed any difference in mileage (in fact, mileage has slightly decreased, but that's probably because computer hasn't adjusted to the new spark plugs yet). I took the old NGK Iridium plugs out of my car at 68,000 miles and they still looked pretty good. Car peppier and smoother with new spark plugs of course. With such an expensive part like an engine, I stick to factory-recommended plugs.

Rated 4 out of 5 by from FACTORY SPARK PLUGS These are factory NGK spark plugs for my 2009 Hyundai Elantra. Engines are expensive, so I like to stick with factory whenever I can. The model is slightly different than factory, and mileage went slightly down (almost not noticeable), but the engine is much smoother and peppier now. Good for another 50,000 or 60,000 miles now.
