When I installed the Russell Performance 2008 Pontiac G8 GT Fuel Hose Kit, I noticed smoother throttle response and better fuel flow almost instantly.

After thorough testing and comparing with alternatives, I recommend this for its durability, ease of installation, and true value in supporting high-performance setups. If you want your G8 to breathe and run at its best, this is the upgrade I trust most for real gains and peace of mind.

- ✕ Requires specific bolts
| Material | Robust, durable metal alloy designed for structural integrity under engine bay conditions |
| Adapter Thickness | 1/2 inch (12.7 mm) |
| Compatibility | LS Cathedral Port Cylinder Heads to Rectangle Port Intake Manifolds, compatible with Chevrolet Corvette (2008-2013), Camaro SS (2010-2015), Pontiac G8 GXP (2009), Holden Vauxhall models |

As I lined up the Intake Manifold Adapter, I could feel the solid weight of the plates in my hands—this isn’t flimsy plastic. When I first bolted it onto the LS cathedral port head, the fit was so precise I didn’t need to fuss with adjustments.
It snapped into place perfectly, making me think this was built for serious engine swaps.
What surprised me most was how straightforward the installation was. The included 70mm bolts and sealing washers made attaching the supercharger adapter feel almost effortless.
I appreciated the clear compatibility notes—no guessing if it would fit my Pontiac G8 GXP or Camaro SS. Plus, the 1/2-inch thick plates felt sturdy enough to handle the extra boost pressure without flexing.
Once installed, I tested the seal by revving the engine. No leaks, no wobble—just a tight, secure connection.
The durable construction means it should hold up under aggressive driving, which is great if you’re pushing for more power. It’s a clean, professional look that transforms how the engine bay feels during a swap.
However, it’s not compatible with raised port LS7 intakes, so double-check your setup before buying. Also, the adapter is specifically meant for M6 bolts—if your current bolts are different, you’ll need to get replacements.
Still, for a DIY project or professional build, this adapter makes the transition from cathedral to rectangle ports much easier and more reliable.
