It delivers much more than a 10x2.75". Going by K&N's formula:
10x2.75 = 518CFM (Max)
Gen-II = 848 CFM (Max) - It's a 6"x4"x9" (6" Round, 4" Smallest Diameter, 9"
Long)
Considering that the stock TB's (and modified as well) will never see 800+
CFM from the engine, the Gen-II is more than adequate.
If you think the Air intake temp is bad, check the temperature on the IAT
sensor...the average is 150+. Remove the rubber flap next to the radiator
(behind the grill next to the A/C lines) and you'll get some cooler air in
there.
