It's time. Since 2006, Rugged Rocks Off Road has been dedicated to providing top-quality Nissan 4x4 parts and accessories, supporting the nissan off-road community with passion and commitment. Your support has been instrumental in my journey, and I have been honored to be a part of your adventures. ​After much consideration, I have decided to close the sale of Nissan parts at Rugged Rocks Off Road to focus on developing advanced mapping products through Rugged Routes at ruggedroutes.com. This direction aims to enhance your off-road experiences with innovative off-road mapping solutions for wide varietey of motorsport vehicles.  A few products on the Rugged Rocks homepage will remain temporarily available during this transition and exisiting orders will be filled. For new Nissan parts enquiries, please contact Shadow Wolf Mfg at: https://shadowwolfmfg.com/
It has truely been a great journey as an integral part of my adult life for nearly 20 years, has shaped me as an individual, and introduced me many new friends. Moving on has been a heavy and emotional decision that should have probably been made years ago to support a healthier lifestyle. Thanks again for all the suport over the years, it's been a ride.
See you on the trail,

  • Nissan Xterra Brute Force Intake by AEM, 4.0L, Gunmetal Grey, 2005-2015 (N50)

Fits years 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015

The AEM 21-8504DC Brute Force Air Intake System produces horsepower and torque gains by replacing the vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Nissan Frontier, Xterra and Pathfinder models. Air enters the system through an extra-large AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located in the original air box space and is protected by a heat shield which is designed to reduce intake air temperature and increase horsepower. The intake tubing is constructed from mandrel-bent aluminum featuring a durable chrome-like finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor and crank case vent hose. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is easy to install with commonly available tools and it is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal. View the 21-8504DC vehicle applications to determine the legal status for each vehicle.
