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.

K&N 77-3071KS Air Intake Product Reviews

Monday, February 18, 2019 - Part 77-3071KS
Received my Performance Air Intake System today. Installation was a breeze and I believe it enhances the look of the entire engine compartment K & N really impressed me with this kit. It installed exactly as advertised and all of the components were top of the line. After having installed varying kits of this or that over the years, it was nice to have a quality product that actually delivers all of the parts and fittings so that no modifications have to be done during the installation. After installation I took the car out for a brief test drive and the boost in power and performance was already apparent. It also sounds great. After driving my Terrain for six years and thinking it was underpowered, I wish I would have found this wonderful solution years ago. KUDOS TO K&N.

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.
