Overview
Not a bolt-on filter or tune, this is a replacement throttle body with a bore of 102mm sized for the Chevrolet LS3 6.2L engine. It is the part that meters air into the intake.
It suits an LS3 owner who wants a bigger bore than the factory throttle body. Beyond that the listing says almost nothing, so box contents, weight, material and sensor details are all unconfirmed.
Who it's for
An engine builder or LS3 owner working through intake upgrades will understand where this part goes. A buyer who wants to know what hardware, gasket or sensors come with it cannot learn that from the listing.
Pros and cons
- Large bore for the LS3
- Direct LS3 6.2L application
- Application stated for the LS3
- Material and finish not listed
- Box contents not listed
- Listed weight is a placeholder
Performance notes
A larger bore lets more air pass the throttle plate at wide open throttle, which matters once the rest of the intake and exhaust can use it. At part throttle the gain is small. The listing offers no flow figure.
