I just got my dual pop charger in on last friday. It does'nt seem like it is worth it for what you get but, do we have a choice? I has potential, but just doesn't seem worth it. Thge kit consits of: another filter and mounting plate(K&N) two alum elbows, 4 blue hose adapters, ten clamps two fittings, and 6 ft of black hose the latter two can be purchased at local hardware store. For 550.00 and the chip is another 100.00 w/250.00 core. Supposed o make considerable difference above 450hp I guess I will see here as soon as I get my engine back together and running again.
