More Towing Power With An Air Intake System

Advanced Flow Engineering Demonstrates How To Install An Air Intake That Adds Power And Profits

By Dan Sanchez

Most truck accessory stores don't realize that they already have a segment of customers that speed shops, and off-road truck centers are desperately trying to get. Truck owners that tow with their vehicles are always in need of extra power. So your customers who purchase hitches and towing accessories, are prime candidates for bolt-on aftermarket performance parts. But many truck accessory stores think it's difficult to install something in the engine. The fact is, installng a performance part like an air intake system is much easier than you think, and aftermarket air intake manfuacturers provide plenty of room for jobbers and dealers to make great profits from selling and installing them.

To demonstrate, we asked AFE to show the installation of their performance air intake system on a Toyota Tundra. The vehicle is used for towing and the owner wanted just a bit of additional power. Dyno results show that the intake can add as much as 12 horsepower and 16 lbs.-ft. of torque, that can definitely add a bit more speed to the vehicle, when towing a heavy trailer up a steep grade.

Installation Procedure

Installing an air intake system requires removing the plastic engine cover and using a screwdriver to loosen the clamps holding the air intake tube to the throttle body.








Before removing the factory intake tube completely, the harness/wiring is disconnected from the Mass Air Flow Sensor located on the intake tube.








Once the clamps are loosened, the intake tube and air filter box lid can be removed from the engine compartment.








The base of the factory air filter lid is held on with one or two bolts that attach it to the fender. These are removed so the filter base can be taken out from the engine compartment. 








The AFE air filter box is larger and provides more air for the filter. It attaches to the same bolt locations as the factory air filter box.








New clamps and hose couplers are attached that will connect the filter box to the air intake tube.








The Mass Air Flow Sensor must be removed from the factory air intake tube, and transferred over to the new AFE intake tube. The sensor is typically held in place with two screws. AFE provides a new gasket and screws. 








The new clamps and couplers are also attached to the ends of the AFE air intake tube prior to installing it onto the throttle body.








The new intake tube is put into position, connecting one end to the filter box and the other to the engine's throttle body.








The factory breather hose connections are attached to the new intake tube, as well as the wiring harness for the Mass Air Flow Sensor.








Once the new intake tube is in place and the clamps are tightened, the high-flow cotton/gauze filter is put into the filter box. It is also connected using a hose clamp and the filter can be cleaned, oiled and reused. It also provides excellent filtration and allows more air to enter into the engine to provide more power.







The completed instalation looks great with a stainless steel cover used in this particular application. Cold air is drawn from the fender and more of it is provided to the engine to create additonal horsepower and torque. Installation time is about 45 minutes to an hour.
