Today I installed a reptile ported tb on my gt and after takeing the old one off I found out the helix tb spacer's gasket[that i put on a year and half ago] was about to give again. I know most people think spacers are not worth anything but I did fell a diffence in respouse and a little power just few horses. Need something that I can trust not to leak I dont need to change the plugs out again because this isnt the first time this has happen.
