This is a really nice part! BD ships it with a stud kit, all of the hardware you need and 1/8NPT plugs for the AUX injection ports. This intake horn has a HUGE plenum volume and the casting is very good quality. Concidering this is one of the lower priced intakes on the market I would say that its the best value for the money. Low RPM response is much improved and high RPM torque is great. Buy it from BC diesel, they have the best price in canada.
