Removing the secondary air injection pump, combi valve, connected hoses, and sensors is very popular when installing a custom catch can kits, breather setups, aftermarket intake manifolds, big turbo setups, and more. When removing any of the SAI systems you will end up with an open port on the cylinder head where the combi valve was installed. Using an IE SAI Block-Off Plate will seal off this port with a small attractive in-house CNC machined aluminum alloy plate. Every plate is machined with an o ring seal so that they seal up perfectly with no fuss, gaskets, or messy sealant. The easy installation takes only a few moments and is completed with our included aerospace grade Viton o ring, stainless steel socket head bolts, and a red anodize finish to compliment your engine bay. 



The IE SAI Block-Off Plate is used when removing factory installed emissions systems. Emissions delete procedures and products should only be used on vehicles registered for off road or race use only. Deleting emissions systems will result in a check engine light and failure to pass state emissions testing.
