    Yep, the 4L in the Tacoma is the last truck engine to use copper plugs. All the V8's and 2010 4L ( 4runner, FJ) use OEM Iridium for long life (100K life).

    Around $26,000 worth of unleaded in the fuel tank.
    Iridium or platinum on plugs won't increase performance, but will increase the service life of the plug.
