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.

 Packaging arrived in excellent condition. Good instructions, logical order, easy to assemble, great fit to throttle body and intake structure. Good performance on vehicle. Improved acceleration, smoother shift transition under acceleration and improved fuel mileage by 1.8% (0.5 mpg) as indicated by actual measurement. Visual appearance in engine compartment is excellent, much better than OEM equipment. Installed on 2012 Equinox LT with 68,178 vehicle miles. Thanks K&N!

 Thank you first off for realizing not everyone who wants more power and better efficiency drives a 400 hp musclecar. My girlfriend bought a new 2012 Chevy Equinox with the 2.4L Ecotec 4-cylinder. Great all-around vehicle but short on power (my opinion). She has always understood the logic of your replacement filters. But because of a possible increase in noise the FIPK was a hard sell. Well, you folks must have designed this one just for her! With the filter enclosed the noise increase is tolerable, power is up, and gas mileage is sure to improve. So thank you again for putting together a kit just for my better half!
