It’s no secret that the expensive stock Cat pipe temp sensor fails often. Quit worrying about going into limp mode for no reason with this simple-to-install block-off kit! The stock sensor is in place to adjust fuel and timing during cold (warm up) and in overheat conditions. Removing this sensor will provide more consistent results when tuning the machine, especially with aftermarket parts. However, it will also disable some factory safety features. An auxiliary EGT gauge is highly recommended when using this product.
