Fitment and application details

Standard Ignition KS234 is used to monitor engine knock so the engine control system can adjust timing based on detonation feedback. This helps maintain proper combustion control on select Audi R8, Audi A8 Quattro, and Volkswagen Touareg applications, along with other listed Audi and Volkswagen models from 2004-2015.

This part cross-references OE-style numbers such as 077905377E and SU14137 for the same application. The KS234 reference is also useful when verifying the correct knock sensor for Audi R8, Audi RS5, and Audi Q7 fitments with brown connector or harness-length notes.
