and 2011 Chevrolet Equinox and GMC Terrain
models with 2.4 liter engines. The 77-3071KS
air intake system is not legal for highway
use in California or other states adopting
California emission standards. Check
for up-to-date information on emissions legality
for specific parts on specific vehicles and
for a list of the other CARB adoption states.
K&N power testing showed an estimated power
gain of 9 horsepower at 4600 RPM with the
77-3071KS air intake installed on a 2010 GMC
Terrain with a 2.4 liter engine. Actual results
will vary depending on the condition of the
vehicle, mileage, weather and other variables.
With the air intake installed we ran the vehicle

  1. We do not recommend using this kit on your application; there could be different mounting points or cause a check engine light, etc.

  2. Has there been an long term testing on the MPG increase? If i can get another 1 or 2 MPG I might make the purchase.

  3. As it is impossible to test for, K&N does not claim or guarantee fuel economy increase. Most of our consumers, however, do report back an increase
