Reliable Bosch Spark Plugs
High-quality spark plugs that fit perfectly and work as expected. Engine runs smoother and starts easily. Durable and dependable — Bosch never disappoints. Great value for maintenance or replacement!

Solid, reliable park plugs
I got these for my 2002 GS430 and boy do they help get all the power out of my engine. I have an exhaust leak and trans leak that leads to a laggy bogged down performance, but by swapping out with these plugs yearly I can keep the power more responsive. I tried other plugs, but these seem to do the best for me in my case. Installation was straight forward and these tightened in place great with a little bit of antiseize.

Good performance and better gas mileage.
The plugs I received were made in Germany. The plugs are almost half the cost of Denso and they perform just as well. I would recommend these plugs.

Use spark plugs? C’mon Amazon
Bought these for my 2003 Thunderbird. All of them were used spark plugs. Useless waste of time. Now I have to return them and go through the pain of re-installing the coil covers and repeating the process all over again.

Compatibility of products as mentioned.
Details of product’s compatibility specially in accessories & parts is very bad. As these products are only exchangeable it’s a loss of the client.But somehow when I have expressed my issues either the product has been changed or I have been refunded.
