Quality versus price
Excellent quality and durability. Certainly a bargain price under a name brand. I would highly recommend!

They work
I've gone 2,000 miles after installing these and the car still runs. I'm not a professional and just looked at several videos on how to change spark plugs. I did it and everything is fine.

Spark plugs.
My car just rolled past 200,000 miles so I wanted to replace the spark plugs before they failed. They came pre-gapped (which I checked) and they are a great value for the money. These also have the fit, quality, and performance I'm looking for.

Muy Buen producto
Todo bien aunque aconsejan a cuanto deben ir calibradas es mejor basarse en el manual de propietario ya que en mi fiesta iban más cerradas por el tipo de motor pero el producto es muy bueno

Resolved 2011 Ford Fiesta misfire & rough idle, & crazy fuel trims
I had 2 issues, throttle position sensor was giving erroneous readings and car was Surging and very rough idle. Spark plugs were changed and that cleared up the rough idle as well as cleaned up the fuel trims, see before and after pics as well as Before video. Throttle body was changed and then the surging stopped (I had a continuous poor throttle position sensor and the car would frequently go into limp mode with a wrench symbol on dash, I was able to temporarily fix issue with OBDii code reader and tapping pedal a few times during startup), I found my throttle body for $90 on Amazon! Car is 200% better and no more Surging or Fuel Trim issues, see before video of crazy fuel trim values and pic After of good fuel trims. Sorry pics/video isn't better quality. Thanks Amazon & Enjoy, my fellow Amazonian Peeps!
