We didn't put the truck on a dyno, so we don't have horsepower numbers to back up the owner's impression of his truck's response to the mods. But we did check the truck's performance before and after we installed in the intake with a G-Tech. The truck was turning 16.77 at 85 mph before we installed the intake. After we installed the intake, the truck ran 16.69 at 86 mph, nearly a 0.10-second e.t. and 1-mph improvement, or about a 10hp increase at the rear wheels. Keep in mind that these are observed times and we didn't adjust for altitude or barometric changes. We tested the intake in the afternoon, when it was several degrees warmer than the cooler temperatures we had in the morning when we tested the performance of just the exhaust. And we know the intake and exhaust combination would have shown a much higher increase in the cooler air, and a 20hp increase isn't out of the question.

Still, the Airaid and Borla combination produced a lot more tire spin off the line than just the Borla exhaust alone. To our minds, that backs up the owner's observation that the combination is making good low-end torque as well as more top-end power.

One other thing we did was use a scan tool to check the intake temperatures compared with the ambient (outside) air temperature. We were surprised to find that the Airaid system actually delivered cooler air to the engine than the stock unit. With the stock unit, driving on the freeway, we measured 74 degrees ambient and 81 degrees in the intake. After installing the Airaid intake system, again driving on the freeway, we measured 79 degrees ambient and 79 degrees on the intake. In stop-and-go driving, we saw about a 2-degree increase in the intake temperature compared with the ambient. We were surprised to see this. We thought for sure the Airaid unit would not induct cooler air than the stock intake. We were pleasantly surprised.

That's all the test information we have on this combo. The next step for you, of course, is to install the gear on your truck. Fortunately, that's a straightforward operation that most sport truck enthusiasts can do with your average set of automotive tools in your garage. You will need a set of jackstands, and a floor jack is the preferred tool to lift your truck onto the jackstands. The only other item you may not have to complete the installation we're doing here is a grinder to provide some clearance between the mufflers and the tow hitch. But other than that, your average set of wrenches and average mechanical skills will do the job.
