Fuel mixture formation: throttle bodies, EGR and sensors

When the mixture is wrong, everything feels wrong: hesitation, high idle, poor economy and emissions codes. This category gathers throttle bodies, EGR valves and coolers, MAP and MAF sensors, intake manifold flaps and vacuum components that meter air and exhaust gas into the engine.

These parts are calibrated per engine variant, so use the vehicle picker or OEM number for an exact match. We carry BOSCH, PIERBURG, VDO and VAICO, with tracked dispatch in 1-2 business days and free 14-day returns.
