alex,
Thanks for the link.
Do you find it amusing that SEMA listed the Clean Air Act info just below the Magnusson Moss Act?
"Sir, the oil from the K&N filter you installed caused the mass air meter to fail thereby allowing the vehicles engine to run lean... Also, the non-Bosch sparkplugs are too 'hot' for your application. The excessive heat from running lean, in turn, caused the catalytic converter to prematurely fail. Sorry, but there is nothing we can do. Therefore, your total for this repair is $2000 thank you very much..."
