I did a search but it was all about how bad Bosch plugs were. I have NGK plugs but I was wondering if Bosch spark plug Wires are fine? They were half the price of NGK ones I think and I'm just trying to pass emissions so replacing the wires seems to be a must for me. Also got the Bosch O2 sensor.

 

get the NGK....you get what you pay for !!!

 

Also i perfer OEM o2 sensor too. i think the OEM o2 sensor is made by NGK but im not sure. Also i heard horror story about bosch fuel pump too.

 

Wires are wires. You'll see no improvement in performance if you spend double the amount on wires. Aftermarket O2 sensor fine, unless you want to spend $125 on a Mazda unit. Factory recommended NGK plugs are fine.
