spark plugs
my car when under load as in 60 mph 5th or 6th gear is very sluggish. have downshift to get it to wanna go. my dad has a Camaro yes I know booooooo but anyways he was told in his to put in the zr1 factory plug and it would be huge help. so we did this and yes tremendous difference. his car was acting the exact same way my 13 5.0 isw. did know if anyone knew of a plug that would fix this issue like it did for my car. ive considered trying the zr1 plug in my car but unsure of the idea. any help??
