Lasted 100K Miles and probably would of gone more but decided to change them out and replace with the same plugs. Excellent plugs, no miss fires or trouble in those 100K miles. Hoping to go another 100K with the new ones. (2010 Kia Soul 2.0L , Gapped @ .041)

Arrived in good condition, easy to install. They are performing well in my 2010 Sebring, 2.4L engine. After 6 months of driving, I've had no issues.

They can't very fast, exactly what was ordered. The spark plugs worked perfectly in the vehicle. Absolutely improved the performance and fuel economy. I have used in 2006 Honda pilot and 2006 Honda civic.

My 2005 Suzuki Forenza sedan was starting rough, although there was no check engine light for a misfire. Its always a good idea to start with basics. The spark plugs were covered in oil, so that meant the spark plugs and valve cover gasket needed replacing. I always stick to Iridium spark plugs as they last longer. This was my first time buying spark plugs from Amazon and just to be safe I made sure the information matched with auto part stores. It was also a little bit cheaper in price. The spark plugs were indeed the problem as it started a little bit better, although I still have to do the valve cover gasket. Never let this go for too long or it could do damage.5 Stars
