I was leaning towards GDP due to price vs performance, but banks cut $250.00 off for the summer, so I'm not sure now.
GDP - eliminates factory grid heater, same voltage as OE, increased air flow to back cylinders.
$512.00 heater
$82.00 Flange
$240.00 intake plenum
The bad now costs a little more.
Banks - increased air flow, throttle response, and mpg.
$750.00 - Whole kit
The bad is not as good in severe cold compared to stock.
Some have experienced a line 6 leak; there is no HP gain for the price increase, as generally expected, to the best of my knowledge.
Thank you for your input.
