Jeep owes more than its name to the General Purpose (GP) vehicles of World War II. It also owes its durability, persona, and go-anywhere capability to the GP’s of yesteryear. The Jeep Wrangler has carried this esteemed mantle with pride from the mid-1980s to present day with a short wheel base and a competent off-road demeanor that has created a massive, loyal group of enthusiasts across the globe. From 1997-2006, the TJ Wrangler reigned supreme with optional Dana axles, 30” wheel and tire packages and a myriad of special edition trim levels. Jeep Wranglers retain their value much better than other vehicles and for good reason, as they still continue to deliver durable performance.
A vehicle with such durability and capability deserves an upgrade that complements it to the core and the AEM 21-8311DC or 21-8311DP Brute Force air intake systems are just the answer. Like the Jeep Wrangler TJ, durability and performance are at the core of the 21-8311DC/21-8311DP Brute Force air intake systems.
1997-2006 Jeep Wrangler TJ 4.0L performance is improved with an AEM mandrel-bent aluminum intake tube which replaces the corrugated plastic factory unit to streamline airflow into the engine. The tube mounts securely to the vehicle with 3/8” thick tig-welded brackets for increased strength, and double-wound hose clamps secure every connection. A throttle body spacer is included as well to help improve low-end torque. The AEM 1997-2006 Jeep Wrangler TJ 4.0L air intake system is available in two finish options; either polished appearance 21-8311DP or a powder coated gunmetal grey 21-8311DC.
The AEM Dryflow non-oiled synthetic air filter is oversized to aid in minimizing restriction and providing a high dirt capacity. Jeep Wranglers thrive in dirty, off-road environments and that’s where the AEM 21-2039DK Dryflow air filter shines, ensuring your TJ gets the clean air it needs to play in the dirt all day long. The Dryflow media is a lofted, non-woven synthetic material supported on both sides by a wire mesh. It utilizes depth loading technology for excellent filtration efficiency and engine protection.
Best of all, the 21-2039DK Dryflow air filter is washable and reusable and does not require any oil. Just once every 100,000 miles or so, depending on driving conditions, remove the filter from the vehicle and service it using the AEM 1-1000 Dryflow air filter cleaner. Furthermore, an application specific air filter heat shield shrouds the filter from radiant heat coming off the engine as well as splashes of water or mud. An AEM Dryflow Pre-Filter Wrap 1-4001, is available separately and offers the AEM air filter additional protection from large debris sticking in the pleats and splashes of water.
The 21-8311DC and 21-8311DP are easy to install and are designed to deliver an increase in horsepower and torque on the Jeep TJ Wrangler 4.0 liter models listed below. Both AEM air intakes for the 1997-2006 Jeep Wrangler 4.0L are 50-state street legal and backed by AEM’s Lifetime Limited Warranty, giving owners the confidence that these durable performance parts will keep up with their Jeep for miles and miles to come.
