2015 RB Accent-not so stock šŸ¤«
1,052 Posts
Anybody using anything other than Iridium plugs on their Accents?
As an old/ new school tuner builder I've thought about using the Champion 445 copper plugs instead of iridium.
Cooper is the better conductor and I do plan on changing plugs when I change oil which is every 10k miles.
Any opinions?
