About this collection

SLS block-off covers

JetPrime SLS block-off kits — machined plates that cleanly cap the secondary air system when a race exhaust and remap make it redundant.

On tuned engines the SLS only distorts lambda readings and clutters the airbox. Block-off plates remove the system properly: exact-fit plates, quality seals, no vacuum leaks. Engine-specific kits as listed.
