Working great, but mechanic said one spark plug had damaged threads, so it was unusable. The packaging was very good. Boxed in open cell foam, I don’t think the plug was damaged during shipment.

Everything came as expected fast shipping

I like that it was the right product for my car. I've Nissan cube, thanks so much.

I’d stay away from these. I made sure they were compatible with my car. But when I installed these, the engine started misfiring and I went to a local car parts dealer and got new spark plugs and coils. That fixed the problem. I don’t recommend using these.

This Marsram kit includes 4 high energy coils and 4 high tech spark plugs. It is used within the automotive industry to give an engine better performance and increase fuel mileage. It gives the engine a hotter spark and allows you to use a wider gap on your spark plugs. The wider gap produces a better spark that helps to burn the air/fuel mixture in the combustion chamber of the head more completely. All this amounts to a cleaner burn and decreased emissions coming out of the exhaust. You will get better gas mileage and help save the planet by reducing pollution that is having harmful effects on our planets Ozone.
