Hey guys, I swapping over my new Ls1 intake to my L33 and the intake didn't come with the needed bolts and my old Truck intake bolts won't work. Does anyone know where I can pick up some of these bolts for cheap, I called the dealership and they qouted me $5 a bolt, which ends up being more than I paid for the intake. Anyone know the bolt thread and size needed?

Also, the three bolts that mount the throttle body to the intake are missing too! Sorry, I know I'm cheap, but I'm trying to keeping my spending as low as possible so that I can put the extra cash toward Mods. Thanks for any help.

 

I broke one of my bolts off in the intake and took one of the good bolts to ACE hardware and found what I needed. I would just go look around and check the threads to make sure they are good. The service manual says M6x1.0x21.8, 13.6 OD.

 

Thanks for the info. I'll try to source the from a parts store.

 

Ok, anyone else with anymore info. I picked up some of the bolts in the post above and they look to be a little short for the bolts that connect the throttle body to the intake. But I'm still a little clueless to the size of the bolts that connect the manifold to the heads.

 

ARP makes some nice chrome intake bolts if you want to splurge a little.

Might just have to go this route. Ok, does anyone have the size and thread specs on these bolts, so I can try to pick them up at Ace hardware or something? Sorry, I don't have a FSM.

 

Another option is the good ol' boneyard.

 

i think the intake bolts are m6 x 1.0 x 105, i found that fastenal can get 110 mm in this size for 0.90 a bolt, but they're special order. not positive, but i think that with a washer the 110 should be ok. i'm gonna try it out anyway.
