I see the part number for the intake manifold, who has the part # for the C7 intake cover?

[typhoon186]

Here you go. good source or pace performance

 

http://www.gmwholesaledirect.com/oe-gm/12628371 or http://www.newgmparts.com/oe-gm/12628371

 

you will need the lower insulator part 12628371.

 

The intake manifold

 

Intake manifold bolts (10 of them). The truck bolts are not long enough.

 

upper insulator 12646904

 

cover 12643576

 

fuel rail covers are optional. if you do get those, you also need the four stud bolts for the cover 11609688. If not, you can use 10mm bolts

Thanks alot!

_{And the extra idler pulley and longer belt. Add a couple large flat washers behind the pulley to space it even with the belt and us the stock alternator bolt with this pulley.}

 

_{you will have to splice 2 wires to move the connector for the fuel vapor purge canister to the passenger side of the inlet to the intake and extend the hose going to the canister. Not hard to do.}

 

_{That should cover it. Have fun!}

Any update guys?

[racerkvn]

I'd love to hear the results as well. I have my C7 intake sitting in the garage... just waiting another couple months before I do it to get a full year under the belt.

Do you have the part number for these? I can't find it.

[typhoon186]

No I don't but they should be available on the C7 parts diagram or through you local GM dealer.

[bigsapper]

OK. Also, can you elaborate on the mods to the wiring & purge canister? Also, do you have a part number for the plug for that back of the manifold?

Got lucky, the intake I bought of ebay came with the bolts. FYI, no diagram I can find on the internet shows the part or the PN.

 

Any help on the plug for the back?

Have you installed the LT-1 intake yet, Tuned?

No I'm still trying to piece everything together. I'm certain when I get done, I'll document this in detail with all the necessary part numbers. And then don't share it. :S

[bigsapper]

BTW, Jason @ Grabiak has been extraordinarily helpful in running down all the part numbers.

Does anyone know the torques for the 10 intake manifoldmain bolts.
