It helps a lot but it is overpriced

K&N black hawk cold intake gave my sierra what it needed, guts & glory combine with magnaflow # 14288 's not loud just right for take offs and mid power both complement each other perfectly for my taste , you can feel the the smooth shifting and power when you press the gas . K&N instructions are very easy to follow would have taken me 30 minutes to finished but I lost the small screws from the maf senor when a gust of wind blew them and couldn't find them . Very satisfied customer!!
