If you're doing a griller delete to 'up perforfamce' just run piping from the apssenger fog up to the intake, or better, run a CAI with said piping and put the grille back in. Just saying, but to each their own.
Grill delete isn't intentional, buying new grill next week, already running pipping from fog light to intake with heat shield, intake temperature is usually around within 5 degrees of outside temperature.
