Can anyone tell me which is a better mod. Pros, cons? Do they produce close to the same HP?

 

They are about the same. The ram air helps when you are on the highway passing somone. They say the faster you go the more air you get.

JB,Hey I dont know about hp dif.,but Fast toys PRO:Good performance gains,esspecially w/ the lid,high flow filter.That freeway stuff mentioned.And better throttle responce@ takeoff,all round actually.
Con:The duct is installed in air path to radiator,so temps rise 10 to 15 degrees,I corrected this w/ the 160 thermo.
