C6 Corvette Base LS3 aFe POWER 92mm Throttle Body (2009–2013)
The aFe POWER 92mm throttle body, part 46-39117, gives your 2009–2013 C6 Corvette Base with the 6.2L LS3 a larger opening than the factory 90mm unit. It replaces the complete throttle body at the original mounting location and connects to the factory electronics. For a Base coupe or convertible owner looking for a bolt-on intake upgrade, this cast-aluminum unit brings a larger bore without requiring an engine tune or a change to the factory mounting points.
With this bolt-on LS3 upgrade, you can increase throttle-body bore size without planning a complete intake-system change. The 46-39117 retains the factory mounting points and electrical connection, and your existing intake tube goes back in place after the swap. That keeps the work focused on the throttle body, with no wiring adaptation or engine tune required for this part. Its cast-aluminum housing carries a 92mm bore in place of the original 90mm opening.
