    I have a '99 2UZ-FE with 170k miles. Driver's side ignition coils (1,3,5,7) and plugs were replaced OEM (Denso) about a year ago by the PO. The passenger's side cylinders (2,4,6,8) were replaced 6 months ago with non-OEM aftermarkets. Today I just had the 3rd of 4 non-OEM coils fail. I clearly...

The truck has about 140k on her now. Check...
