Smog ports March 17, 2015, 12:34:51 AM Hi guys,Ya know those smog ports on the back of the cylinder heads? yes, I know trick flow makes block off inserts for this. But what I wanna know is, can you install those WITH the engine still in the car? Or is the firewall too close?Any help is appreciatedKyle Quote Selected

I've also heard a spark plug is the same thread, but i haven't verified that. Quote Selected
