product's finish was great. design was intuitive, installation of the baffle itself into the pan was easy.
But, fitting onto the engine was not. fabrication was needed to remove a hole from the oil level sensor assembly hole to easily fit onto the car. Might be different if the pan was installed without the transmission, but installation with the trans on needed some fabrication.
