this is the most high performance power lid on the market:
its the less dense ,outer layer from a POS toomey filter, flows plenty of air for all of you that are gona give me shit
and yes its filthy, but looks brand new after a few splashes of gas and a run under the hose
note the high quality zip ties and window screen for the front section:

yea its messy,drilled the top out years ago with a 1" hole drill bit as u can tell, before the +10hp powerlid conversion i recently did

precision cuts on the metal brackets to hold the foam in place

window screen, high class
eat your heart out k&n -
