iridium spark plugs, I've been told are THE BOMB...but could never afford them personally~
the ignition system on these trucks is overkill already. Free up the intake and exhaust and get a good tune, electric fans, wieght reduction. Or forced induction (low psi of course if your not building the motor). But still 40hp is asking alot unless you go supercharged
