Market analysis
How much does a used Lexus NX300 throttle body cost?
Asking prices for a used Lexus NX300 throttle body are unusually spread out: the top listing asks about 4 times what the cheapest does, so which unit you pick matters more than the median. Condition matters: grade-A units (lowest mileage, best condition) carry roughly a 26% premium over grade-B stock, with grade-A medians at $126.
Model year matters too: 2018 units carry the lowest median at $126, while 2020 tops the table at $131. Parts from 2015–2021 are interchangeable, so if the 2018 fits your vehicle, it offers the best value across 7 compatible years.
Against comparable vehicles, the Lexus NX300 sits 5% above the Mercedes S Class ($120), 26% above the Mercedes GLE Class ($100), and 38% above the Mercedes E Class ($91) for the same part. The “similar vehicles” cards below open each comparison guide.
Buying a used throttle body: what to check
- Inspect bore and butterfly blade for carbon: Check the throttle plate for heavy carbon varnish or sticky shaft movement that causes rough engine idle.
- Verify electric actuator plug pins: Check electronic throttle actuator plug pins for corrosion, bent spades, or cracked plastic connector shrouds.
- Check butterfly shaft play and spring return: Wiggle the throttle shaft to check for worn bronze bushings or weak return springs on cable-operated units.
- Confirm vacuum nipples and coolant heating tubes: Check metal vacuum nipples and coolant heating passage tubes for corrosion, clogging, or breakage.
- Perform idle relearn procedure after install: Run an electronic throttle position calibration scan tool routine to clear high-idle fault codes.
