copper or aluminum are pretty good sump plug washers. i think most if not all toyota's use the fiber ones and they work really well. you could drill out the plates adapter holes and re-tap to right thread size/pitch or put in a helicoil.
the last cop that pulled me over for a "random" breath test and look under the hood said as long as the pod is fully enclosed its not a defect. i only have some shitty ally cover i made over mine and i didn't get done. as for EPA i'd say you would need the stocko air box, i have mine in the shed
received and installed mine. they're bright lil fckrs lol. i had to solder a bit of copper wire on to the globes wire cause they were flickering when moved. work perfect now. Thank you.
