i have an intake for sale, no longer needed as the itb project went well. i have no idea what the original application was, but it worked perfectly in my 85 si. the filter rested on the passenger wheel arch, and i had no problems despite it not being securely mounted. the pipe has a 2.5" od, and both clamps on the pipe are turbo type t bolt clamps. i did not have the proper sized clamp for the throttle body, but the worm drive clamp on that side never gave me any issues. the silicone reducer fits nice and snug to the throttle body, and although the filter is still usable, it would probably need replacing sometime in the near future. you will have to get a little creative if you have a stock battery, but the lithium battery i used also dropped almost all of the weight of the lead acid battery.
i am no longer going to need this intake, and i would like to know that it is going to be used rather than sit in storage forever. i have no idea what it is worth, so please feel free to make a reasonable offer. i am not looking to get rich selling a used intake, i just want to make it worth my time.
