AFE Filtration Patented Pro-Guard 7
Advanced Flow Engineering received a US Patent for a high capacity hybrid multi-layer automotive air filter sold under the trade name “Pro-GUARD 7.” The patent covers a multi layer progressive density filtration media that simultaneously improves performance while increasing protection and increasing service intervals. The patent recognizes the design with respect to:
- Filtration Efficiency (ability to remove a high percentage of particulates in the intake air)
- Filter Capacity (amount of particulates a filter can hold before excessively restricting airflow)
- Air Restriction Pro-Guard’s combination of performance & protection & extended service is attributed to a “depth-loading media” that combines 5 layers of progressively finer gauze with 2 layers of progressively finer spun bond polyester. These layers create a low restriction air path that traps a wide range of particle sizes over a service interval 3 to 5 times longer than OE paper elements.
These filters are cleanable and reusable. For more info contact 951-279-4050 or www.afefilters.com.

Powermaster Ultratorque® For Jeeps
Powermaster offers two ULTRATorque Starters for ’71-87 AMC Jeeps with 232, 258, 304, or 360 engines, and another for ’87- up Jeeps with 4.0L motors, both with the most torque at 250 ft.-lbs. These starters were developed to meet Jeep enthusiast demands, especially rock crawlers. The starter has the 2.5kw needed for fast starting highly modified race motors. It also uses Hitachi’s silhouette as a design parameter to accommodate headers, engine adapters and plates, and starter pinions, so you don’t have to change anything to use it. In a performance environment where a modified engine offers more rotational resistance than stock, torque is most important to overcome that resistance. High compression, large displacement, tight rings, blowers and more require these starters. Your package includes a dyno sheet with the exact performance of the enclosed starter-which offers assurance that it’s built to consistent, statistically controlled standards, and that it’s been dyno tested through the entire power range. For more tech info contact 865-688-6953 or www.powermastermotorsports.com.

K&N Replacement Air Filters
Replace the disposable air filter in your truck with a high-flow, washable and reusable K&N Filter. These filters fit the factory location and help maintain peak performance. Unlike disposable filters, they use a unique pleated design comprised of an oiled cotton fabric, sandwiched between two layers of epoxy-coated aluminum screen that captures airborne dirt particles while allowing high volume airflow. These particles then cling to the filter’s outside and actually become part of the filtering media. The pleating increases the surface area, which in turn assists airflow and extends service intervals. Better dirt retention, better airflow plus a million mile limited warranty. Cost savings is another attribute as this filter can be cleaned up to 25 times with the easy two-step process of washing and re-oiling. They also offer a Recharger® kit which includes everything necessary to keep the filter in top condition, with simple, detailed instructions.

K&N Jeep Liberty FIPK ®
Add power and improved throttle response to your Jeep Liberty 3.7L V-6 engine with a K&N 57-Series Fuel Injection Performance Kit (FIPK). The high-flow low restriction air filter element is this system’s cornerstone. It can be cleaned dozens of times, and will save you money over the life of your truck. Surrounding the air filter element is a heat reflective metal shield. By isolating the filter from engine heat, the shield helps keep incoming air cool for a denser, more powerful intake charge. Incoming air is further isolated from engine heat by a composite tube that connects the air filter to the fuel injection intake. This tube is designed to optimize airflow velocity in order to improve throttle response and torque throughout the entire rpm range. Kit bolts on easily in less than 90 minutes and requires only basic hand tools. All FIPK kits are 50-state legal and backed by their million mile limited warranty. For more tech info please contact 800-858-3333 or www.knfilters.com.

Powermaster Jumpstarts Jeeps
Powermaster’s XSTorque™ Starters for ’71-87 AMC Jeeps are versatile in their ability to fit 232, 258, 304, 360, and 401 engines, and have the most torque: at 200 ft.-lbs. They have no clearance issues — and will clear any oil pan where the OE starter works, and all headers made for those engines. Rockcrawlers helped them develop this product — with cranking power for up to 18:1 compression, with no heat soak problems and reduced weight for lean, mean competition. High compression, large displacement, tight rings, blowers or other factors require a starter with enough torque, and these starters have it. Your package includes a dyno sheet with the exact performance of your starter — not a figure representative of a range of starters. These sheets are your assurance that your product is built to consistent, statistically controlled standards, and that it’s been dyno tested through the entire power range.

Edelbrock TI-Tech™-Coated Jeep Headers
Jeep drivers with 4.0L engines can get a performance boost with Edelbrock’s new shorty, performance header coated with Ti-TECH™. The Tri-Y design header bolts directly to the factory exhaust system. Using 1-1/2”-diameter 409 stainless steel primary tubes, a 1/2”-thick laser-cut port flange and thick laser-cut collector flange, the header improves performance for 4.0L 1991-1999 Jeeps. Edelbrock R&D says with this new coating headers have heat stability to 1,600° F and at higher temperatures, the coating will flux, becoming harder and more abrasion-resistant, unlike organic coatings that chalk and lose adhesion with extreme heat. These headers bolt directly to the factory crossover pipe with no cutting or welding required for installation. The tubing is mandrel-bent to help ensure superior flow.
