Market analysis
Why does the Infiniti QX80 intake manifold cost more?
A used Infiniti QX80 intake manifold carries a median asking price of $236, which is 0% higher than the Ram 3500 at $235. Supply also plays a role: Ram 3500 has 2,097 priced listings versus 337 for Infiniti QX80, and more listings generally mean more choices and more competitive pricing.
The Ram 3500 average ($394) runs 68% above its median ($235), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Only 69% of Infiniti QX80 intake manifold listings include a posted price (337 of 485 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The Ram 3500 intake manifold is interchangeable across 20 model years versus just 11 for the Infiniti QX80 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade B (good) condition, the Infiniti QX80 is 47% cheaper ($246 vs $461) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used intake manifold
- Inspect composite or metal manifolds for hairline heat cracks, blown runner gaskets, or oil soaking inside the plenum from bad PCV systems.
- Verify throttle body flange bolt pattern, MAP sensor mounting port, and vacuum port locations across model years and engine generations.
- Check variable intake runner flaps (IMTV or DISA valves) and actuator vacuum bladders or electric motors for proper movement without binding.
- Examine head mounting flanges for warping or deep gouges that prevent a vacuum-tight seal against the intake gaskets.
