Celica Forums General Discussion Exterior spark plugs and wires

wut are the best spark plugs and wires for the gts

GTS already runs Denso iridium plugs, can't get much better than that...

As for wires, forget it, there aren't any, our cars use a COP (coil-on-plug) setup, which uses individual ignition coils connected directly to each spark plug (hence, no need for plug wires)

If you're looking for an ignition upgrade, install a ground wire kit.

Denso Iridiums sp?

As for spark plug wires, it is my understanding that you don't need to upgrade those or can't because we have individual coil packs instead of a distributor. Spark plug wires are for distributor applications only.

You can get a better battery like a optima red/yellow top.

what does the ground wire kit do exactly and for an upgraded starter what would you guys recomend
