Do youguys think I voided my warranty by adding a air fuel ratio gauge, a temp gauge and a oil pressure gauge? I put the temp sensor in the radiator hose and the oil pressure in between the oil filter and block... The tapped into the sending wir on oxygen sensor... I also drilled thru the firwall.. What do you guys think???????

 

No such thing unless your gauges causes technical issue to the engine and such then it voids it. Well, of course don't tell the dealership that the gauges caused the issue if that ever happens.

 

why did you drill through the firewall!!??
