Well, this past weekend my brother and I installed the full-length Injen CAI on my LS3. The instructions were very straightforward and I feel pretty confident I could install a CAI by myself in the future.
As for performance, this thing is a beast! The acceleration feels smooth and consistent, and the power increase is highly noticeable, especially in 4th and 5th. Give it a little gas, and you can hear the intake taking a huge breath of air!
Sadly I don't have official numbers, but I am completely satisfied (even without a dyno tune.) Injen FTW!!!
1. Loosening and removing the front-left tire.
2. Tire is off. Remove the wheel-well guard (not pictured.)
3. Removing the factory air box.
4. Inside the air box after the filter is removed.
5. Stock intake removed.
6. Stock Windshield Wiper Fluid Reservoir removed.
7. Injen Windshield Wiper Fluid Reservoir installed. This step was very simple and only took about 10 minutes.
8. Closeup of the intake clamp on the engine.
9. Intake tube installed and clamped on.
10. Air filter installed and clamped.
11. Install complete with engine cover back on.
I forgot to make a "before" video of what it sounds like stock, but I'll be making an "after" video later.
