Borla
Header 2.5 liter
(Stainless steel) |
The
stock Subaru headers are extremely restrictive and clearly built
to save costs, not make power. To remedy this design flaw, we
offer the Borla Stainless steel headers. These headers feature
nice, smooth mandrel bends with a much more effective layout which
improves mid and high RPM torque and power. Not only do you gain
performance but you also get the 'boxer' sound the Subarus are
famous for.

- Agency Power Subaru 2.5L, Crank Pulley
|

The all new Agency Power lightweight crank pulley for your Subaru EJ20, EJ22, and EJ25 motor is now available. This fits almost any WRX, STI, 2.5RS and more. The CNC machined aluminum pulley is made from high grade 6061 material and finished in either a Flat Black or Gloss Silver color. Each pulley has the Agency Power text laser engraved. The pulley has been broached for a perfect fit and the redesigned lightweight center gives you the best possible advantage over the competition.
The Agency Power pulley is the same diameter as the stock pulley. Keeping the diameter the same allows no issues to occur with the alternator as under driven pulleys do sometimes. Weighing only 1.0lbs, it is almost 5lbs lighter then stock. This is also the lightest crank pulley on the market. This gives you quicker throttle response as well as more horsepower and torque. Saving on rotating mass results in better performance.
The AP pulley is a great performance part for your Impreza, WRX, STI, Legacy, and Forester vehicle.

This
Intake is Matched with the 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 dis-assembled to be cleaned
and then re-assembled after cleanings or to change the color of
the foam filtering element.
Only available in Polished w/ Black Filter

95-99 Subaru Impreza / Forester / Legacy performance airflow meter intake Kit
This clever modification allows using the factory intake tubing, while replacing the restrictive stock air filter box.
The MAF intake filter kit replaces the OEM air box and converts vehicles equipped with an air mass meter into an open element intake system. The result is - highest possible horsepower and torque gain. This increases the performance for your ride, due to the restriction of an airflow meter and the OEM air filter system. The airflow meter intake system comes with the Dragon Filter and all necessary mounting hardware and, silicon adapters to complete the installation.

Subaru Impreza - Forester 1995-1999 / Legacy 2.5L 1995-2002: $319.99

This MAF intake filter kit replaces the OEM air box and converts vehicles equipped with an air mass meter into an open element intake system.
- Cleans incoming air with free flowing washable cotton gauze media
- Draws ambient air safely with no worry about rain
- Straightens out air flow = more torque & hp
Air does not like to change direction, the more turns it has to make the slower it will travel its that simple. By removing your restrictive stock paper air filter and box which makes air turn a considerable amount and replacing it with our in-line filter will create a performance gain. Air that travels through a Jet Stream Intake System does so with little directional change & with its taipered design creating a venturi (speeds up air) effect puts this unique filter in a leauge of its own. And the sound, simply put; awsome nothing compares to the sound of a Jet Stream Intake System, top of the heap. In true racing conditions you can create a ram air set-up by simple using an inlet funnel or scoop, doesn't get any better than that. So if your interested in buying the best cold air intake system available on the market today - LOOK NO FURTHER.
Only available in Polished tube w/ Black Filter and Black, Blue or Red Coupler
Some fabrication may be necessary for fitment.

Subaru Impreza / Forester / Legacy / Baja 2.5L 2000-2004 Performance Intake for MAP Sensor Cars

These 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 these intake systems are 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.

Short Ram Intake Kit
05+ RS/Forester/Baja/Legacy having 'MAF' Sensor

With any vehicle, the more air you can get in and then out will make you go faster! Of course, there is a little more engineering then that on an intake system.
The aluminum tube intake is equipped with a CNC machined 6061 aluminum MAF piece to ensure proper air flow readings. The intake uses a cone filter for maximum air flow with safe filtering from the outside elements. The cone filter will stay clean and is reusable for the life of the vehicle. The intake is mounted to the frame with a high shine silver aluminum “L” bracket using the stock intake box mount to hold it securely. Connecting the intake to the air inlet pipe is done with a 3 inch silicone coupler.
The intakes are available in Wrinkle Red or Polished. Intakes are available with either a black, blue, or red silicone coupler.
Note: Because of the wide range of MAF programming, occasionally a Subaru may see a CEL, which can be removed by using engine management. This is more likely to occur in 06-08 cars. The probability of seeing a CEL is one out of one hundred, but they do happen.

SMT
PIGGY-BACK ECU
|
 |
The
SMT PIGGY-BACK ECU has been designed to answer the question how
is my car going to get tuned?
The
SMT 'piggyback' ECU is designed to correct fueling and timing. This
is a wire in unit that can be sent to meet the needs of your car.
The SMT is simple to install, (must be soldered in) and includes
wiring diagrams, and installation instructions. The SMT can be programmed
by you using the 'tuning cable'.
SMT-USER
KIT $999.99
Kit
Includes:
Harness
Tuning
Cable
Software & Manuals
The SMT comes with easy to use software. The unique features of SMT are:
Boost control
The boost control feature is applicable to turbo installations where the boost must be controlled. This is particular
important when the engine is NOT decompressed, and when a rather small turbo is used. In all these cases the engine has the tendency to ping between 2000-3000 RPM. The boost control can reduce the boost at the critical RPM and then increase the boost significantly at the higher RPMs where the airflow is restricted. The Boost control feature can also be used as a standalone function for aftermarket boost control.
Wide band lambda
3 Analog Screens
The SMT has 3analog screens. With the SMT every output is fixed to a certain wire. This makes the unit easy to understand and wire up, giving the unit two connectors with a total of 36 wires.
Since there are so many features in the SMT, the SMT will be shipped with only a few wires connected and loose pins to make up the rest of the connector. This is done to make a clean installation and not have excess wires hanging around.
Software
The SMT's software will have an easy to use screen layout. The screens will have tuning versatility with columns featuring engine temp, as well as, air temp per screen. Featuring quick upload and download times. The software can also be configured as to how you want the screens to look. Different task buttons can be shifted around to suite your needs. Then you can also set the software to display the screens in your preferred language. Screens not in use can also be switched off to make tuning easier and quicker.
7 Tuning Screens
The SMT has 7 tuning screens, each with its own global settings. The global settings per screen will only be applicable to that screen.
Max Recordings
The SMT records: Maximum RPM, Maximum MAP, Maximum Engine temperature, Maximum Air temperature
The SMT can be programmed for multiple numbers of teeth. With this design it is now possible to do crank triggers that have multiple teeth with multiple gaps.
The SMT runs parallel to work with engines with multiple teeth pickup.
