Lincoln Knock Sensor

If you own Lincoln and want to keep it in top shape, choosing OEM Knock Sensor is a smart move. They are precisely engineered and follow strict factory standards. They are made in advanced facilities that use cutting edge technology. Each part goes through thorough testing to confirm strength and safety, so you can trust it. FordPartsDeal.com gives you genuine Lincoln Knock Sensor at some of the affordable online prices without cutting quality. Every OEM Lincoln part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Lincoln Knock Sensor monitors aggressive combustion noise and immediately allows the engine to change timing. Lincoln rebels against noise with its Quiet Flight concept, and cabins, tuned body panels, and piping are all done to quiet engine rumble only to have the riders clearly hear conversations inside the cabin and arrive less tired. Lincoln began in 1917, entered Ford in 1922, and was expanded by combining Detroit toughness with civilized road manners, demonstrating that luxury could be combined with reliability and working efficiency. Lincoln fills everyday drivers with Co-Pilot360 warnings, lane runaway, and blind-spot illuminations, auto high beams, parking support, and ActiveGlide that allows you to drive on the highways without using your hands under camera supervision. Lincoln is lined with soft leather, knurled metal, and crisp screens, and every year tech is updated so the owners feel that their purchase continues to be enhanced way beyond the first ride. Knock Sensor mounts on the block, converts sharp vibration on detonation to voltage, feeds PCM which subsequently retards the spark a few milliseconds later to prevent ping, preserve pistons, and maintain power even when fuel quality is poor. The piezoelectric core of the Knock Sensor measures the pressure peaks per cylinder and the computer can adjust timing on each side of the bank, sometimes reducing turbo boost, providing a more comfortable pull on the hills without the clamor. The second advantage of Knock Sensor is that it can fit any engine in the lineup, so all engines have the protection of detonation, a longer spark-plug life, and the chance to use regular unleaded without concern on hot summer days.
