The K&N 63-9032-1 is an AirCharger cold air intake for the 4.7L V8 in the Toyota Tundra. It replaces the factory airbox and filter with a high-density polyethylene tube and a red, oiled cotton-gauze conical filter. The manufacturer describes the tube as rotationally molded and designed to last the life of the vehicle. Compared with the restrictive stock setup, the larger conical filter and smoother tube aim to deliver more airflow, and K&N's own dyno testing on a 2007 Tundra estimated a gain of about 8 HP at 4717 RPM. Because the filter is washable and reusable, owners avoid recurring paper-filter purchases; the manufacturer rates it for up to 100,000 miles of normal highway driving between cleanings.

This kit mounts in the factory locations and is sold as a direct replacement, so no tuning is required and the install stays simple for a home mechanic. Buyers should note that the manufacturer does not certify this system for California or other CARB-adopting states, where it is not legal for sale or use on pollution-controlled vehicles. Fitment is listed by the manufacturer for the 2007-2009 Tundra, with the 2008-2009 Sequoia also covered; if your truck is a 2007-2008 model, confirm the application against the manufacturer's listing before ordering. Plan on roughly 90 minutes with common hand tools, and follow the manufacturer's instruction sheet closely for hose clamp torque and tube alignment. The kit carries the manufacturer's lifetime limited warranty.
No. The manufacturer states this intake is not legal for sale or use in California on any pollution-controlled motor vehicle, and it is not CARB certified.
The manufacturer rates the washable, oiled cotton-gauze filter for up to 100,000 miles under normal highway driving before it needs service. Harsh or dusty conditions will shorten that interval.
The manufacturer lists the 2007-2009 Toyota Tundra with the 4.7L V8, and also lists the 2008-2009 Toyota Sequoia. Some listings reference only 2007-2008 for this kit, so confirm your exact model year with the manufacturer before ordering.
The manufacturer's installation video shows the replacement process, and it estimates that the job can usually be completed in under 90 minutes with common hand tools. Other manufacturer material puts it closer to an hour, so plan for a little extra time if this is your first intake swap. The kit replaces the factory filter and airbox and uses the stock mounting points, which keeps the job straightforward. Watch the clamp and hose routing near the intake tube, and follow the manufacturer's instruction sheet for full details. Owners on user forums often recommend checking for fit against the heat shield and nearby components before final tightening.
