Subscribing and wondering out loud . . .

1) Intake tube fitment?
2) Is this a pure bolt-on mod on an '08?
3) Has anyone done a dyno test back-to-back with the 87MM and 90MM TBs to prove a HP increase?

+2 on MIT fitment, I have read somewhere (I am still looking for the link), that the 90mm is around 7-10 hp upgrade over the 87mm, not sure if I believe that yet......

Outside diameter is same as stock,fits nice and snug just like the stock one did.

very cheap mod! Even though it might not show gains on the rollers, it makes drivability so much better! No hesitation, very smooth acceleration, helps from having to push on pedal so hard(requires less pedal travel to accelerate compared to 87mm) Makes me wonder how a stage 2ported TB would work.

2) Is this a pure bolt-on mod on an '08? - I believe so on all NNBS not sure why it would fit mine and not yours.
3) Has anyone done a dyno test back-to-back with the 87MM and 90MM TBs to prove a HP increase?
- No idea

No fitment issues. I'm sure the upgraded TB is prolly the equivalent to a UDP. Im sure those gains were on a FBO truck.
