I've put both Bosch Platimun plus 4s and Champion copper cores in the TE, no difference.

My friend the mechanic only uses platinum plugs these days, as they are all resistor plugs originally.

If you have idle problems, switch back to the coppers, but otherwise the platinums are fine, I use them in everything with no problems.

The only time you get trouble is if you have too high a resistance in the wires, ends, and plugs combined, and most replacement wire sets these days aren't resistor (or have the correct low resistance ends).
