I dont think you realize that Techs dont get paid to stand around and look up the proper cold air intake for your Nissan Sentra. They get paid a precent of an hour to install a part and thats it. Do you think that any of them give a shit? no they dont. If the MAF sensor failed isnt your car still coverd under a factory warrenty? Does your header delete on of your cats? Because thats going to cause problems.
When it really comes down to it, your putting a bunch of parts on a car that dont belong there. You can sit here and tell me how there nismo and all that bullshit but it dosent matter. that car was made for fuel economey not to be a race car. Its not the cars fault the drivers and idiot…
