Air Switching Valve Block-Off Plates

The block off plates are the only way to isolate the secondary air injection system and the related pressure sensor(s) from the exhaust which should only be used with "The Original" SAIS Bypass Kit. By completely isolating the system from the exhaust, the pressure sensors are prevented from causing valve stuck open trouble codes which are the main cause of limp mode when this system fails. Even though a system is bypassed and should never run again, the Exhaust No. 2 Valves can still leak exhaust and cause future trouble. Installing the block off plates is the only way to prevent future valve trouble and limp mode. Again, it is just best to install and forget about it.

Detailed and illustrated Installation Instructions are easy to follow and include all details for each component of the Bypass Kit.
