K&N Fuel Injection Performance Kits (FIPK's) are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow “chain” robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Fuel Injection Performance Kits (FIPK) virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. K&N Fuel Injection Performance Kits (FIPK) are truly state-of-the-art. K&N starts with the largest conical shaped high-flow air filter that can fit into the engine compartment while using factory holes and mounting points. This extra filter size provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box. The oversized air filter also captures and holds more dirt increasing the service life before a cleaning is required (up to 100,000 miles). When possible, the filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. Next the filter is attached to a rotationally molded tube made from interlaced High Density Polyethylene (HDPE). This process allows the tube to be precisely shaped to reduce turbulence and accelerate airflow into the engine. This is why some tubes have unique shapes that are specifically engineered for each application. Finally the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today.

Kinetix Racing Velocity Intake Manifold for Nissan/Infiniti VQ35DE We took the very popular SSV manifold and went over every aspect of its design to make the most impactful improvements. As our customers and the 350z/g35 marketplace continue to improve the power potential of their engines, the SSV needed a redesign to accommodate the the higher power output of these vehicles. The new Velocity Manifold is geared for higher flow and higher RPM power gains. This allows for even larger power gains in the many F/I vehicles out there. The new Velocity Plenum design maximizes flow to the furthest cylinders by creating a "venturi" effect. By gradually narrowing the plenum chamber, the air speed must increase to satisfy the equation of continuity. Improved flow to all cylinders also means an improved smoother A/F curve that requires less tuning in F/I applications, and near ZERO tuning in N/A vehicles. This manifold is constructed entirely of Stainless Steel, then polished out for an absolute beautiful finished product that looks as great as it performs. We chose stainless because of its great thermal properties, conducting 10X!! less heat than aluminum and eliminating much of the manifold's mass, which greatly helps with heat soak. Stainless is considerably more expensive than aluminum, but the finish shines brighter and longer. The overall manifold SAVES 10lbs of weight over stock! Precision TIG welding throughout, and a CNC cut 3/8" main flange. All mandrel bent runners and charge tube, this manifold rivals the quality of other intakes twice its price. We improved greatly upon the factory plenum designs. The factory lower plenum has many dips and turns which do not promote good airflow and creates turbulence inside your factory intake. We developed a straight shot design, eliminating the twists, turns, and obstructions. We then took each runner and also added velocity stack inlets to each individual runner for even better performance. This Manifold is a DIRECT replacement and will work with any aftermarket intake. It also allows you the ability to use the factory strut bar, or any aftermarket strut bar. We also have available an engine cover specifically designed for our manifold. We recommend an A/F tuning on Forced Induction vehicles (turbo and supercharged) after installation of the Velocity Manifold in order to maximize power and overall engine reliability. Tuning is generally not needed in Naturally Aspirated (N/A) applications. Each manifold is supplied with all necessary hardware and instructions. There is an additional port supplied which can be used for boost gauges, etc. ** Newly released Velocity Intake Manifold replaces our older SSV version with many improvements: * Velocity plenum chamber design - Equal air flow between cylinders * 12% more plenum chamber volume * 10% short intake runners for more flow and higher HP potential * Smoother A/F curve - less tuning required - more consistent power * High RPM power !! 30.5hp gains at 6800 rpm * Thicker gauge construction for higher boost - warranty up to 30psi * Ready to install - Includes all necessary hardware and gaskets for installation Learn More

The K&N 69-7078TS Typhoon air intake system is a free-flowing, mandrel-bent aluminum tube air induction system designed to fit some Nissan 370Z and Infiniti G37 models. The restrictive factory air filters and air intake housings are replaced by the K&N Typhoon air intake system which is designed to dramatically reduce air flow restriction as it smoothes and straightens air flow. This allows your engine to inhale a larger amount of air than the factory air intakes. More air means more usable power and acceleration throughout the engine's RPM range. The 69-7078TS air intake comes with dual black rubber topped K&N high-flow air filters and heat shields that install into the previous air box spaces. Air is directed through the intake tubes into the engine's throttle bodies for a guaranteed power gain. The intake tubes have an attractive silver powder-coated finish that's made to last and accommodate the factory mass air sensors and crank case vent hoses. The oversized cone shaped air filters can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake system is relatively easy to install usually in 90 minutes or less using existing factory mounting points. The tools needed are a couple of screwdrivers, pliers, a ratchet set and several wrenches. Some Typhoon air intakes are not legal for sale or use in California and other states adopting California emission standards while others are CARB exempt and 50 state legal. Check the K&N catalog or website for vehicle applications and specific CARB status for each vehicle and air intake. Learn More

Weapon*R Dragon Intake Systems are one of the mostly highly rated intake systems in the world. Used in many countries in many different forms of racing. Also recently rated "Best Overall Performer", outperforming Cold Air & Short Ram Intake systems, in the 2003 Tuner Performance Reports, Intake system Battle. Our Intake Systems are CNC Mandrel Bent out of 6061 aluminum, and then Hand Tig Welded to ensure a positive seal and proper fitment. Each one of our intake systems is carefully tuned, by matching the engines displacement, air intake capacity and airspeed to the intake systems tube size and length, maximizing every engines performance output. This Intake is matched with our World Famous Dragon Filter, which provides maximum airflow, with the protection of high quality dense Poly Urethane Foam. Many studies have shown Flow rates of up to 80% more Air and Better Dirt Filtration with Foam Filter than the conventional cotton filter. The Dragon Filter features a Computer CAD Designed and Flow benched Tested Velocity Stack, which greatly increases airflow and air volume into the engine, therefore increasing engine performance. Another one of the Dragon Filters positive features are the capability to be disassembled to be cleaned and then re-assembled after cleanings or to change the color of the foam filtering element.
