Civic SI & 1.5t FK8td high pressure line upgrade





      We have taken the same great treatment that out Fk8 high pressure line upgrade and added it to the civic Si high pressure line. This line is proven to add up to 10% more fuel on a stock Si fuel pump. It will also be standard on our New Si fuel system.
