I am very satisfied with this system. There is a noticeable improvement in horsepower and throttle response on my 2009 Subaru WRX. I highly recommend this product.
While not a mechanic, I decided I could install this myself. Let me just say it wasn't quite the piece of cake I was hoping for, due mostly to a very tight fit (both a curse and a blessing). Beyond that, the one thing I can say for sure is that after 3 weeks, there is no question I'm getting better mileage.
I ordered this part online as a gift for by boyfriend and had a few questions about the product and emailed a AEM staff person and they got back to me ASAP with answers. Great customer service and supper friendly staff!! I would totally recommend ordering online from them! And my order was shipped and only took a few days for it to be delivered.
I really like the intake so far. I have only had it now for a couple of weeks now but it seems to be working great. I haven't noticed any mpg gains but it has made it sound a little better than the stock one. I hope to see a change on the drag strip or dino soon. One thing I might add suggest is a military discount. Or if you have one I wasn't aware.
I was very pleased with the CAI I received and would gladly recommend y'all to any of my friends...I did however have a little confusion with a few of the pictures. It appeared to have a snug fit in the pictures that came with the installation instructions but when I put it together it wasn't snug at all until I actually put the part in my WRX...just took a little common sense. Thank you so much AEM!
