I'd search for this, but the moderator disabled the search function. What s the PN for the NGK...... 6's i think. I have a chip, and a 2lb pulley to put in + my signature. Also. If im going to put in a nitrous system (she's a daily driver) do i need to change my plugs too? i dont want to foul the plugs really fast bc im not going to use the N2O alot... just for the occational beat down
