This is our ProBld EFI intake manifold. We are so proud of this piece! We started the design with a 3D printed piece, to verify fitment. Once we got all the fitment issues figured out, we sent it to get CNC machined.
These intakes are machined by a 5 axis (the good stuff, no machine lines) CNC machine, out of a solid pice of aluminum. It has a super smooth interior for perfect flow. It port matches all performance heads at 27.5mm intake size.
No big power robbing step down. No sharp edges. We used a silicone boot rather than a basic rubber boot for style and durability. We use a viton "x-ring" style o-ring for best sealing, and gas won’t deform the viton, as it’s a synthetic rubber. Not to mention, It’s anodized gold to match the other intake pieces we sell. It will accept a 33mm outer throttle body.
