  • Perfect Bosch Aftermarket

They are exactly what I needed and now my car is running like a polished machine. The quality of the plugs are top notch. I have great throttle response and smooth acceleration at low rpms. The price is was more affordable the any part store. I would recommend these plugs to anyone.
