BOSCH Spark Plug reviews

Works perfectly with G4LA engine (2018 1.2L petrol i20), the engine vibration went away, there was a nasty resonance around 2300RPM. I was afraid at first as it goes 1mm deeper than the original spark plugs (Champion). Remains to be seen how long it will last, but with the 7 year Bosch warranty I'm not afraid. It is important to torque it correctly to 23NM and don't use any lubricant or anti-seize on the thread as per the manufacturers notes. Use dielectric grease on the plugs.

Replaced my NGK platinum 70k miles for these bosh ones. I could feel the difference in the first crack of the engine. Car came up alive, more responsive.

I have a Toyota Aygo AB10 2013 and swapped to this Bosch product. I seems like a good product and the engine runs ok with it.

yearly replacement for my car, not sure if I can feel difference but seem like starts better in cold days.

Europarts were selling one spark plug for £20 instead of a pack of spark plugs for a reasonable price

Bosch products are great quality. These provide a solid performance and are very reasonably priced.

amazing difference these plug's made!!! Instantly more Powerful burn and increased performance
