Market analysis
Why does the Mercedes S Class intake manifold cost more?
A used Mercedes S Class intake manifold carries a median asking price of $181, which is 24% higher than the Infiniti QX50 at $146. Supply also plays a role: Mercedes S Class has 2,637 priced listings versus 393 for Infiniti QX50, and more listings generally mean more choices and more competitive pricing.
Only 69% of Mercedes S Class intake manifold listings include a posted price (2,637 of 3,847 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The Infiniti QX50 intake manifold is interchangeable across 17 model years versus just 12 for the Mercedes S Class — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade B (good) condition, the Infiniti QX50 is 65% cheaper ($100 vs $287) — 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.
