K&N’s Typhoon intake for the Cobalt SS Turbo uses a 3.25″ inlet filter and steps down in size to clamp directly onto the stock turbo.
The kit comes with a heat shield for the engine bay and all necessary hardware for install. Tube color is a very nice semi flat black.
K&N dyno testing shows a gain of 12.2HP at the wheels!
