I tried searching but seems like its not finding anything... any supramania member/dealer have this for sale. I put in a jdm motor that only came with the rear block off plate and not the one on the side where the EGR goes. So I started the car after the swap and forgot to cover it with a EGR block off plate. A lot of noise comes out of there with the motor running.. would it cause it to run really sluggish as well?? EGR block off plate anyone?
