Iridium Ix Series Spark Plug, Sold Individually
Spark plugs came in good condition
Car part came in 1-3 business days which isn’t bad only down side is if you order multiple pieces they might come separately and you get charged shipping multiple times too but besides that everything was good

Ordered plugs and coil packs, both came very quickly and were in great condition, fit with no problem, and did exactly as advertised. I have been ordering parts for three different vehicles and am pleased with the parts and the service of everything ordered. Will continue to order from their company in the future.
