We've talked about the Subaru WRX STi before - specifically our new EVO1206 air induction system - which you can read about here. However there are many of you that want to take the more traditional route to more horsepower and torque for your Subaru.
Here is our SP1206. The SP Series Cold Air Intake is a high-tech, fine-tuned oxygen delivery system. The aerospace-grade T-6061 aluminum tubing is CNC mandrel bent, and the TIG welded brackets are perfectly positioned for a balanced fit inside your exact year, make and model. Plus, everything from the composite flanges to the urethane air filter is meticulously tested and tuned on Injen's in-house Dynojet.
Features:
Injen's SP Series Cold Air Intake is custom-designed for a precise fit on your exact year, make and model
Specifically built for radical top-end power gains in high-performance autos
Specially engineered to ride right behind your front bumper, where it gathers fresher, denser, colder air
Your SP Series Cold Air Intake unleashes your engine's power potential by force-feeding rich oxygen into your cylinders, which improves combustion efficiency
Wrought from premium slabs of aerospace-grade T-6061 billet aluminum—famous for its high strength, light weight and excellent corrosion resistance
For unrestricted air flow, the SP Series Cold Air Intake is CNC mandrel bent
Every SP Series Cold Air Intake includes a reusable, high-performance cotton-gauze air filter with a built-in velocity stack
Dyno-proven for maximum, reliable horsepower gains
Your SP Series Cold Air Intake comes with stainless steel clamps, silicone hoses and detailed instructions for a simple at-home installation
Injen's groundbreaking rubber "vibra-mount" system cushions against engine torque
Made with pride in the USA
Now vehicle owners have a choice between the new innovative EVO1206 Air Induction System, or the equally innovative, more traditional SP1206 Cold Air Intake.
Each will provide you with the Horsepower and Torque gains you're looking for your Subaru.
Our good friends over at Slam'd visited the factory to watch us Dyno Test Injen's new Evolution air induction system for the Subaru WRX, the EVO1206. They have done a terrific post on the install which you can read about here.
“First and foremost, this is the only hybrid cold air intake system available for the STI – meaning we have an aluminum tube that includes our patented air fusion tuning process, along with a fully rotational molded, enclosed induction system.” – Jay Crouch, Injen Technology
Here are the results from the Dyno Test: "After a proper install owners can expect to see output boosted by around 26 horses and 35.5 foot-pounds of twist, for a total of 271awhp at ~5400prm and 275awtq at ~4600rpm; very impressive indeed! "
Thanks for the visit, Guys! We're glad you were impressed with our Evolution series. Feel free to come by anytime!
Injen Technology has shown you our EVO1206 Evolution Air Intake system before on this blog, but today we are pleased to answer all the requests for more details on this CAI and other products to give you the "complete package" - tuned air intake, high flow down pipe, and stainless steel catback exhaust - for your Subaru WRX. Let's start out with the video of these three products below:
First is the EVO 1206 Evolution Cold Air Rotomolded Induction System. Each cold air intake in the Evolution line is designed for the following:
Dyno-tuned as a System for GUARANTEED SAFE Horsepower and Torque gains.
Officially the largest SuperNano-Web dry filter on the market.
The first stand alone air filter chamber for ample on-demand air supply.
Sleek and sexy design.
The first totally enclosed air box.
Functional front air scoop that attaches to the enclosed air box to draw in cold air.
Designed and built in the USA from cross-linked polyethylene for outstanding durability and heat insulation.
Durable stainless steel hardware.
Perfect OE fitment.
The EVO1206 is from Injen Technology - the company that was the first to tune cars with mass air flow sensors that came out in 2002. Namely the Mazda 6 and the Subaru WRX. Although Injen has been issued tuning patents [07359795, and 07669571], other intake manufactures continue to copy thestep down tuning processfor air/fuel ratios. Injen has also taken it a step further by filing for 3rd and 4th tuning process patents for short term/long term fuel trim levels
[ 07721699 and 07757548 ] that guarantees you peace of mind.
All Injen technology products are CAD-designed and built as 3-D models in our Pomona, CA facility so they can integrate easily with OE parts for the perfect fit. After an exhaustive scanning, modeling and design process, the Evolution cold air intakes are prototyped and 3-D printed for test-fitting and development on actual vehicles. It is our rigorous testing and development phases that allow us to come up with so many "firsts" in air intakes: - The largest SuperNano web dry filter on the market... - The first stand-alone air filter chamber
From this R&D phase, we move to the production and manufacturing phase, roto-molding cross-linked polyethylene from 5 axis CNC machined molds. Because this process requires the mold to be heated and cooled, it takes considerably longer to produce products than other molding process like injection molding. However the results speak for themselves in terms of heat insulation and durability, creating a cooler, on-demand air supply for your Subaru.
Let's take a look at how the EVO1206 fits installed in the engine compartment.
You can see in the video how easily the EVO1206 is installed, bringing you the horsepower and torque gains you want.
+26 Horsepower and +36 Torque.
Check out the Dyno test below.
In addition to the EVO1206, the complete Subaru WRX Sti package includes the SES1205DP - 3" High-Flow Catted Down-Pipe. This is a 76mm Downpipe with a divided wastegate discharge & high flow catalytic converter. Injen Super SES stainless downpipes are carefully engineered and tested to offer the flow that you need for your turbo setup. These downpipes are manufactured from CNC mandrel-bent, 100 percent 304 stainless steel to provide the additional performance you're looking for from your turbocharged vehicle. A non-catted down pipe is also available: SES1204 DP
To top off the complete package is the Injen SES1206TT - 3" to Dual 60mm Cat-Back Exhaust. This is a 76mm full stainless steel cat-back exhaust with dual oval muffler and quad titanium burnt tips. Features include:
OE exhaust replacement with high-flow, super-efficient piping that immediately frees-up extra horsepower and torque
Manufactured from pure T-304 stainless steel for incredible longevity, durability and superior corrosion resistance
The SES1205DP is CNC mandrel bent for smooth, unrestricted exhaust flow and reduces back pressure
Flanges are all CNC machined for a tight, leak-free fit
Your SES Performance Exhaust System's seams are TIG-welded for superior accuracy and a clean finish
Includes all mounting hardware and instructions for a 100% bolt on installation
Made in the USA
Injen backs your SES Performance Exhaust System with a 1-year warranty
