unfortunately , after 20,000 miles it caused many troubles to my engine, and gives me a very very very high fuel consumption,

Installed in a 2013 Kia Sportage. It runs smoother than it did (have not checked MPG yet) but the engine is a bit quieter. Easy install in this vehicle.

Fit right in like a glove. Never had a problem with Bosch plugs and coils. I'll still go with this brand as long as they keep up the quality.
