Review on Spectre Performance 764 Profile Plenum by Corey Bigglesworth

Do not purchase this product if you have a 4 cylinder holly with vacuum secondary pumps. I did a lot of research on this before buying it and no one mentioned that it doesn't clean the secondary membrane. I am angry! I had to cut the manual choke wire bracket off the carb and remove the choke lever and still had to dent the bottom of the airbox with a hammer to install it.
