Map Sensor with seal Fits TC 99-10 Fuel Injected models (Except 08-10 Touring), 00-06 big twin carb models, 04-06 XL, replaces OEM # 32316-99The manifold absolute pressure sensor (MAP) provides instantaneous manifold pressure information to the engines electronic control unit (ECU). The data is used to calculate air density and determine the engines air mass flow rate, which in turn determines the required fuel metering for optimum combustion and influence the advance or retard of ignition timing. A faulty MAP sensor will usually display symptoms of a rough running engine during acceleration, deceleration or at idle.FEULING Sensors meet or exceed OE specifications, assembled in the U.S.A.Feuling does not recommend tuning beyond stock emissions standards.*QUALIFIED MANUFACTURER DECLARED REPLACEMENT PART FITS: Fits TC 99-10 Fuel Injected models (Except 08-10 Touring), 00-06 big twin carb models, 04-06 XL, replaces OEM # 32316-99 Replacement Part for OEM Number(s) 3231699 3241610 3241699 3241710 3242498 3242499 Specs PRODUCT NAME SENSOR TYPE MAP UNITS EACH RIDING STYLE STREET
