What made you choose this particular product?
Price, Availability, Brand
What were you trying to accomplish by adding this product?
Better throttle response, more induction sound
Was it easy install? Any installation tips that will help others?
Install was fairly easy, accomplished with typical hand tools.
Once you’ve had a chance to use the product, did it meet your expectations?
Quality of materials and workmanship was good. However, the filter caused the wheel well liner to bulge inward a bit as it did not have quite enough room.
