I installed a new K&M air kit like the one advertised here without the breather box. sounds great and I think it has better pickup but i dont know. the question is i hear pinging at high rpms around 4500 . im wondering if it was allways there or is it new now that i can haer it . its not loud but its there. i have a 96 awd 5.0 v8 auto.and i use 87 octane gas. could it be gas? everything is new on it . ie plugs wires... any guess?? runs great but that ping bothers me could it be the new kit? thanx mike
