At K&N, engineers can utilize the OE electronic controls to monitor a motor while it is put through all its paces on the Engine Test Stand. As a result we can develop products that are modern and capable of interacting with electronics including the On Board Diagnostic (OBD) system.

The OBD II system has been built into all 1996 and later light-duty vehicles and trucks and is required by the Clean Air Act Amendments of 1990. OBD systems are designed to monitor the performance of some of an engine’s major components, including the components which control emissions. In newer vehicles the emission controls start at the ignition key.

The new concepts that K&N develops will help K&N design and manufacture the best products possible. For more than 35 years, K&N has continued to be pioneer with numerous improvements to its products.
