TRD spark plugs cord

[Maximun]

When using trd's cable what are the engine improvements?

they are a slightly thicker lead over standard and give and improvment over standard....however if there is any proof im not sure, as most people have changed the standard ones that have done like 80k for a new set, so you should notice a slight change.

slightly better spark due to less resistance in the cable (more thick) so current will be delivered slightly better & stronger to the plug! Its a vry minimal difference to notice by itself but gd to upgrade the leads when power is increased!
