Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters & intake systems for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter apart from the competition. We currently offer aftermarket air filters for passenger cars, light trucks and SUVs. We also have many applications for round racing and universal clamp-on filters. To find your particular application, please use our new search engines. If you do not see your particular application listed, please contact us. Twisted Steel 409 Stainless Steel Shorty Header Nissan 350Z /Infiniti G35 03-05 V6-3.5L Features: •Constructed of 1-5/8in. 16-gauge 304 stainless steel primary tubing •Mandrel-bent for unrestricted flow •3-to-1 formed collectors decrease turbulence and increases exhaust velocity •Optimized Tube Lengths Improve Flow and Performance •100% hand TIG-welded construction ensures optimal stre ngth and durability Test Results •In testing; the headers produced a max gain of+9 horsepower and+12 ft. lbs. of torque verified by our in house dyno (tested on 2003 Nissan 350Z V6-3.5L with stock y-pipe) •Potential for up to+10 horsepower and+13 lbs. x ft. of torque when combined with aFe s per formance Y-Pipe (P/N 48-36104-YC) Factory Mounting Locations: These headers are a direct bolt-on installation which requires no cutting or drilling to provide a hassle-free installation. Formed Collectors: 3-to-1 formed collectors decrease turbulence and increases exhaust velocity. The result is in creased horsepower; torque and improved throttle response. Heavy Duty Flanges: 1-5/8in. Thick 1-piece flanges are used to prevent warpage to ensure a leak-free seal over the life of the vehicle. Optimized Tube Lengths: Tube lengths are optimized for true pulse control technology which improves flow and performance. aFe headers and exhaust are engineered and manufactured in our Corona; California manufacturing facility. Note: This system is not currently CARB exempt and is not available for sale in California or for use on any vehicle registered with the California Department of Motor Vehicle.
