Speaking of DingKing - IT DOESN'T WORK [at least for my car]! Save your money and remember, all these 'amazing' TV products that seem too good to be true are just that! Another example would be AirFlowMaster thing - it does up your HPs and sort of improves milage BUT it makes your engine so much louder [very noticable]. I'd stay away from these new age wonders...
