So I'm *finally* getting towards the end of my cam swap.... Can anyone tell me what the black metal brackets do at the rear of the intake manifold? They really don't seem necessary and I'm tempted to leave them off the car.
I removed the engine cover, an if the brackets your talking about are the ones I see looking somewhat like a letter L laid out flat with a turned up section dead behind the fuel rails and both having a turn down finger behind the manifold, they sort of look useless to me also. Maybe they are there to prevent any possible rearward moving of the fuel rails (if that's possible). If its those brackets, I guess its a "take your best guess " on what to do with them.
I took these two brackets off as well as the little silver bracket at the front of the intake on the drivers side. I have searched and searched and still have not found a for sure reason the factory installed any of these or what they are for. Does anyone know for sure?
The brackets at the back of the fuel rails are there to prevent the rails from popping out in front end impacts and reduce the likelihood of a fire. The smaller silver bracket is to ground the fuel rail. All the other connections and bolts are into plastic. To prevent static build up and keep everything grounded, the silver bracket connect from one of the fuel rail mounting bolts which only connect to plastic to one of the intake manifold mounting bolts which bolt into the block.
