I have Bosch Iridiums, they work fine for me. I heard the NGK ones arent bad either but I would say just go with OEM. I tbh dont see much of a difference.

As mentioned, NGK or Denso... Either is fine... Mixed reports of other plugs... I'll never use anything but one of those two...

E3 "diamond fire" plugs are junk all your paying for is that they look cool they will inevitably cause misfires

Default Ok

So could that still be causing my issues with the car not wanting to run at idle? I have recently replaced all 3 ignition coils plug wires and put the E 3 plugs in. As well as new crank sensor and cam senor
