The K&N 77-3071KS Air Intake fits some Chevrolet Equinox, and GMC Terrain models. See vehicle applications link for details.
The K&N 77-3071KS high-flow performance air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some GMC Terrain Chevrolet Equinox models. The restrictive factory air filter and air intake housing on your vehicle are replaced by this K&N air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. The improved air flow allows your engine to inhale a larger amount of air than it would from the stock air intake. More air means more usable power and acceleration throughout your engine’s RPM range. The 77-3071KS air intake comes with a chrome topped K&N high-flow air filter and a lidded heat shield that installs into the previous air box space. Air is directed through the intake tube into the engine’s throttle body for a guaranteed power gain. The intake tube has an attractive silver powder-coat finish that's made to last and it accommodates the factory mass air sensor, air injection hose (where equipped) and a replacement silicone crank case vent hose. The oversized cone shaped air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a screwdriver, ratchet set and several wrenches. Some K&N 77 series air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake.

Fantastic, well made product. Extremely easy to install. Instant noticable increase in available power and throttle response. The new Sound is incredible! Best HP+ boost for the money. Highly reccomended for anyone with a sluggish 2.4L equinox. It brought my car to life.

Not the cheapest intake out there but can always expect a good product from K&N. Directions sent sucked due to saying it's for a 2010-11 when you ordered for a 2016 and then they are cheap and don't print the color version so print it for yourself off the site in color if you want to be able to see better. Performance wise I live in the mile high city so oxygen is limited. My car felt doggy on takeoff before the intake. After, I notice much quicker throttle response and performance overall. Glad I bought it. Haven't had it long enough to test fuel mileage but I'd assume it'll increase with efficiency.

Bought the system due to rear seal blowout due to PCV system freezing in cold weather. Was covered partially by GM, and mod'd the oil fill cap to let the crankcase have additional venting. GM has a intake design for the PVC system that traps moisture, and lets it freeze causing the issue. Discussed it with them, but don't expect they will change the design to cure the problem. High mileage engine, probably what you have to look forward to if you leave the stock intake installed during colder weather, short city drives. Installed new K&N intake, during first good cold snap, and with original oil fill cap being installed, noticed that the moisture issue was back. Haven't blown another rear seal, but did have a slight leak of oil again, but didn't blow the rear seal out again, so PCV line and connection work slightly better than stock. Threw the mod'd oil fill cap back in again. will be looking for a breather filter from K&N to allow for better crankcase venting to ditch the moisture buildup problem. Will update if I can to show what option I decided to go with. Decent vehicle, hate to ditch it and take a bath due to a slight design issue. Engine does run nicer with intake, little more jam to it.
