after reading about HD intakes, i decided to change the piping on mine. first off what i had was a Ractive heat shield filter on the MAF, then a 4" to 3" adapter then some 4" aliminum dryer hose going down to the hole in the splash guard and angled forward. this system was better than stock and sounded great.
i wanted less heat transfer so i went ahead and made a 3" ABS system. from the 4 to 3 adapter i have a 90* bend then 7" of pipe and then a 45* bend angling the end to scoop up some air. everything fit great and looks nicely. both systems have wire mesh over the intake hole to keep out leaves and stuff as i did collect some before putting the mesh on.
first thing i notice while driving is that the intake is WAY quieter. i used to hear it over the exhaust until about 4k, now all i hear is the exhaust. i didn't notice any increase or decrease, which dissapointed me. i was hoping for colder air from less heat transfer, air coming in faster as the piping decreased from 4" to 3", and the ABS is smooth inside while the dryer hose was ribbed for her pleasure.
oh well, i'm gonna drive with it like this for a while and see how i like it. i can always change it back.
