Modify plenum?????

[jk kelly]

What do you do to modify the plenum and why?

Port it out for better air flow.

Port match the opening to the throttle body, cut out the square egr tower inside and also the lower intake needs to have the square egr tower milled out of it also. Like Raf said this is done to improve air flow and help get more air to the two front cylinders. What is your current setup on your car, there is alot that can be done if it is stock.

yup... Port it to the TB an cut the egr tab off then add a RJC POWER PLATE

Weld a piece into the back of it to function just like a power plate. Without the powerplate restriction
