2001 Jeep Wrangler TJ - HP & Torque Increases For Jeep Wranglers - TechPosted in Features on February 1, 2006
In using the 4WD&SU '01 Jeep Wrangler TJ as a daily driver for the last few years, we're constantly seeking ways to improve performance without hampering fuel economy. The vehicle has become a virtual parts guinea pig as we bolt on and test various performance-enhancing products to see if they function as intended and offer the promised power improvements. Continuing this ritual, we picked up Airaid's newest design of its Cool Air Dam Intake System, along with a Poweraid throttle-body spacer, to see what this power-up kit had to offer.
We didn't have a chance to get the TJ on a before-and-after dyno, but the "seat-of-our-pants" dyno noticed a definite increase in peppiness with plenty more low-end pull for getting away from a dead stop, such as planting the pedal for a steep hill climb or to get that extra lunge over a tricky obstacle. Airaid indicates that in-house tests of the system yielded an additional 14 lb-ft torque (at low rpm) and 11 hp. Not too shabby numbers for a bolt-on kit, especially considering the ease of installation. We were also impressed that the air dam and tube fit so snugly within the engine bay, unobstructed by the on-board air compressor and dual battery tray, and using some of the last underhood space available. The system is also covered by Airaid's "No Hassle Warranty."
The Airaid Cool Air Dam Intake System includes everything needed for a basic installation using a flat-head screwdriver and 4 socket sizes. The kit also includes an Airaid Premium SynthaFlow-series high-flow air filter that's said to significantly increase airflow over the stock air filter assembly. The air filter is also said to provide superior filtration and is easily cleanable for a long life. Airaid also offers kits for a variety of Jeep applications in addition to Nissan Xterra, Frontier, Titan, and Armada; Toyota Tacoma; and many GM, Ford, and Dodge engines.
