The K&N 63-3064-1 is a 63 Series AirCharger cold air intake for the 2.9L four-cylinder in 2007 to 2012 Chevrolet Colorado and GMC Canyon trucks. It replaces the factory air filter, airbox, and intake tube with a roto-molded high-density polyethylene tube, a powder-coated heat shield, and a large conical oiled-cotton filter. The manufacturer says the oversized filter and smoother tube lower intake restriction, which lets the engine draw in more air than the stock setup.
Over a stock intake, the appeal is the combination of airflow, filtration, and longevity. The manufacturer describes the power gain as guaranteed and cites roughly 9 HP at 4862 RPM in its published materials, while owners on user forums report mixed results, with some noting sharper throttle response and a stronger intake note and others seeing little change. Compared with a generic drop-in filter, this kit is vehicle-specific, mounts in the factory locations, and uses a washable filter that the manufacturer rates for about 100,000 miles of normal highway driving between cleanings. Buyers should note it is not legal for sale or use in California on pollution-controlled vehicles.
Search terms this kit matches include 2.9L Colorado cold air intake, GMC Canyon 2.9 L4 CAI, 2007-2012 Colorado intake upgrade, and K&N 63 Series install. Installation is reasonably approachable: the manufacturer says most installs finish in under an hour with basic hand tools, and the kit includes its own mass airflow sensor adapter and gasket. Disconnect the battery only after noting radio and memory settings, and follow the sheet closely to avoid damaging the tube, throttle body, or sensor.
The manufacturer lists fitment for 2007 through 2012 Chevrolet Colorado and GMC Canyon trucks with the 2.9L L4 engine. The product title references 07-09, so confirm your truck's year and engine before ordering.
The manufacturer's install sheet recommends that customers do not discard the factory air intake, so store it in case you need to return the truck to stock or sell it later.
The manufacturer rates the washable oiled cotton filter for roughly 100,000 miles of normal highway driving before cleaning. Harsher dust or off-road conditions will shorten that interval.
The manufacturer states the typical installation can be completed in less than an hour with simple hand tools. Its install sheet lists a ratchet extension, 13mm and 10mm sockets, a flat-blade screwdriver, a 5/8" wrench, a 10mm wrench, a T20 Torx bit, and 3mm and 4mm Allen keys. Disconnecting the negative battery cable erases stored memory settings, so record them first. The sheet also covers unplugging the mass air sensor, removing the airbox bolts (the nut used on earlier trucks is not present on 2008 and later models), and removing the intake resonator. Some trucks have an air injection pump hose that needs its adapter reattached. Owners on user forums commonly advise confirming the mass airflow sensor orientation and tightening the clamps carefully, since the sensor wire can be snug once everything is seated.
