Product Description

For years you've been asking us for intakes, and for years we've silently worked to create a solution that sets itself apart from the rest. We examined and tested current offerings, and identified their shortcomings. We formed theories, and over months of testing designs we proved them. Combined with our advanced research and development program, we fully utilized our engineering resources to design and manufacture what we believe is the most comprehensive intake solution available for the 2005-2009 Subaru Legacy GT.

This intake was designed with tuners in mind! The consistency of the airflow through the MAF sensor makes this intake very predictable and is as easy to tune as the stock airbox. Intial dyno testing and design theory validation was completed on our 2012 WRX, equipped with a GrimmSpeed 3-Port EBCS, Catted Downpipe, Catless Uppipe and TMIC. We then worked with a local product tester and his 2005 Legacy GT wagon to verify performance on the intended model.

The chart on the left shows a comparison of the same car with a stock intake and stock tune, followed by the stock intake with the applicable COBB Stg2 OTS Map. Then, the GrimmSpeed intake was installed and the MAF scaled properly for use with the same map. Lastly, wastegate duty cycle was also scaled to increase boost pressure from 15.5psi to 18psi.

The chart in the middle shows the GrimmSpeed Intake vs. Another Popular Intake running on the same recommended COBB OTS Stg2 93OCT +SF Map. Using this tune, the GrimmSpeed intake provides an additional 21whp at the peak and up to 30whp earlier in the powerband. It should be noted that both of these runs were very rich and left quite a bit of power on the table. This is the reason that we recommend a professional tune.

Finally, the chart on the right is similar to the chart above, but the GrimmSpeed intake has been custom dyno tuned by DB Performance in Rogers, MN. The additional 5lbs of boost safely nets 40whp and nearly 50ftlb of torque. This image has been resized. Click this bar to view the full image.
