Got a Lexus GS350 (or similar model) from around 2007-2015 with engine trouble? Could be the fuel injectors. This ACROPIX set gives you 6 brand new injector nozzles, ready to replace old, clogged, or leaking ones. They're direct-fit replacements for OEM numbers 23209-31030 and 23250-31030, so no mods needed. Specs: 2-pin design, silver tone with purple accents, DC 12V, same flow rate as original. Fits Lexus GS350, GS450h, GS460, IS F, IS350, LS460, and LS600h for specific years (check the list to be sure!). Important: Fuel injectors affect your engine's air/fuel mix, so after installing these, your car might need a tune-up or ECU adjustment. We highly recommend getting a pro mechanic to install them—they've got the tools and know-how. Also, check other engine components while you're at it. Comes as a 6-piece set. Keep your Lexus running smooth!
