Chevrolet Performance MAP Sensors
Chevrolet Performance MAP sensors are high-quality, direct-fit replacements for worn or malfunctioning MAP (manifold absolute pressure) sensors. These sensors accurately produce voltage or frequency as intake manifold pressure changes--and the computer uses this information to measure engine load so that the ignition timing can be advanced and retarded as needed. The MAP sensors are available to fit most GM engines, including the LS Series. They're built from factory-style materials and easily install in the stock location, so no modifications are necessary.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
