Audi TT Ignition Coils & Parts

The operation of an ignition coil is based on the principles of electrical induction; its job is increasing the voltage taken from the battery and multiplying it thousands of times. Ignition coils utilize contact breakers, capacitors, and power transistors, while receiving electrical current from the source. The current is then fed through the ignition wires to the spark plugs, which ignite the combustive air-and-fuel mixture. Present-day autos have one or several coils per cylinder or a pair of cylinders. Ignition coils are made up of several parts.

Their inner workings are based around a laminated core, which features a pair of highly-conductive copper wires. The coil’s main winding is made up of only a few wire coils, with the auxiliary winding made up of thousands of windings of thinner wires. The whole electric assembly is submerged into a cylinder with cooling oil or epoxy resin, which are designed to transfer the accumulated heat into the surrounding atmosphere. When the coils on your Audi TT fail, the engine misfires, which causes poor fuel efficiency and drivability problems like stalling, insufficient power, and rough idling. To restore the proper performance of your sports car, go with Audi TT ignition coils & components that you see right here – they're manufactured and tested to OE performance specs for proper engine efficiency.
