Here is what i did to my 1989 RX-7 FC3S GTUs.
I cut out the front bumper in the center to allow more air to enter the center section behind the bumper.This is where the stock air pick up tube is on a 2nd generation RX-7.I used to have a Akimoto air filter on it but decided to go with a stock K & N drop in.
I did notice a difference and believe colder air is fed to the intake .This mod and might actualy lower intake pressure..
You can also do this to any Bumper on any car.Want to allow more air to enter the front.can help cool your radiator better ..Also this does reduce some weight!!lol
Also later on another post i will have pics of my front bumper supports taken off and a vent cut into the TURBO II bumper.I'll probably do it for my FMIC..so it will be larger than the one pictured here..
