Buy Mustang parts Ltd, an original LS7 Intake Manifold paired with a low-mileage Throttle Body from a C6 Z06 is a core performance asset. The LS7’s induction system is unique due to its large-bore architecture, which was designed to feed the 427 cubic inch (7.0L) displacement of the most powerful naturally aspirated engine in Corvette history.

2. The “82mm” vs. “90mm” Clarification
There is often confusion in the luxury parts market regarding the LS7 throttle body size:
-
The Reality: The factory LS7 throttle body is 90mm.
-
The 82mm Reference: Smaller 82mm units are typically found on European luxury V8s (like Mercedes-AMG) or older GM truck LS variants.
-
Business Note: If you are listing this for Buy Mustang parts Ltd, always market it as the 90mm unit. Selling a 90mm LS7 throttle body to someone looking for an “82mm intake” upgrade is a common performance mod for smaller LS engines, but for the C6 Z06, 90mm is the factory standard.
3. Inventory Value & “Grade A” Status (2026)
With the C6 Z06 reaching modern classic status, OEM “take-off” parts are increasing in value:
-
Manifold + Throttle Body + Rails: $850 – $1,100 (Complete Assembly).
-
Throttle Body Only: $250 – $350.
-
Manifold Only: $500 – $750.
