Market analysis
Why does the Mercedes E Class throttle body cost more?
A used Mercedes E Class throttle body carries a median asking price of $91, which is 25% higher than the Kia Optima at $73. Supply also plays a role: Mercedes E Class has 1,979 priced listings versus 757 for Kia Optima, and more listings generally mean more choices and more competitive pricing.
The Mercedes E Class average ($126) runs 38% above its median ($91), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 9 model years for the Mercedes E Class (2015–2023) but only 6 for the Kia Optima (2015–2020), so the Mercedes E Class data reflects a broader range of generations.
Only 63% of Kia Optima throttle body listings include a posted price (757 of 1,206 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
At Grade A (excellent) condition, the Kia Optima is 25% cheaper ($75 vs $100) — the gap narrows compared to the overall median difference.
Buyer's checklist
What to check before buying a used throttle body
- Distinguish between electronic drive-by-wire throttle bodies and traditional cable-actuated units with Idle Air Control (IAC) valves.
- Check bore diameter and butterfly valve throat for heavy carbon build-up, shaft play, or scoring along the aluminum bore wall.
- Inspect electronic sensor housing cover and connector pins for moisture entry, cracks, or burnt circuit traces.
- Verify coolant heating bypass nipple locations and vacuum port configurations, which vary by vehicle region and emission spec.
