Market analysis
Why does the Lexus NX300 throttle body cost more?
A used Lexus NX300 throttle body carries a median asking price of $126, which is 5% higher than the Mercedes S Class at $120. Supply also plays a role: Mercedes S Class has 2,707 priced listings versus 128 for Lexus NX300, and more listings generally mean more choices and more competitive pricing.
The Mercedes S Class average ($147) runs 23% above its median ($120), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 8 model years for the Mercedes S Class (2015–2022) but only 4 for the Lexus NX300 (2018–2021), so the Mercedes S Class data reflects a broader range of generations.
Only 67% of Lexus NX300 throttle body listings include a posted price (128 of 191 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The Mercedes S Class throttle body is interchangeable across 22 model years versus just 7 for the Lexus NX300 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
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.
