UPD V8 Biturbo Cold air boost kit
i was kind of surprised when i first drove the car and thought i hit some moisture spots on the street but its done it many times now on dry surfaces so while not a dyno test this intake kit (to me) seems to add some power and also the throttle feel (to me, again) seems more responsive. i've never dyno'd, but been relying on my dashcommad app for data on HP/torque/0-60 so will see what those read with the Filters in compared to my baseline stock but i definitely feel improvement above stock performance (will add that my stock filters were dirty so getting new clean filters had to help).
here are some pics...its a 30 min install unless you drop one of the aluminum barrel spacers in the engine bay and have to dig around to find it like i did (yes, dumb *** move...)
thanks to shardul for the great service and answering my questions and sending me the replacement barrel spacer which i never found

some pics.

Red rectangular spacer, with Green Filter #7171 and longer screws/barrel spacers
OEM filter - pretty dirty, airboxes had to be cleaned out also

driver side view
nice touch adding the aluminum spacer for the front small air box covers on each side so they are flush with the rest of the airbox
install complete, less the engine cover
all buttoned up... nice inexpensive mod if you are stock to get a noticeable little bump in power and performance

I can hear the sound slightly more with the radio and a/c off, otherwise no real change.
Shardul can you let me know what the size of the longer bolts are or parts #? I lost one while trying to align the spacer into the depths of the engine but saved the spacer.




Need some paper work that shows the increases... a video link would be even better because I could take a picture of a Lamborghini post it and whos to know the difference.
