Installation took 2 minutes. No issues running lean or anything related to needing a tune like some forums may say. This product is a steal for $40! And the box design is dope too.
The HKS filter fit easily into the stock airbox. However, make sure you have the proper filter orientation. The filter is rectangular, not square. Just had to turn the filter 90 degrees to get the right fit. Seemed my WRX accelerated a bit smoother but the stock filter was pretty well filled with dust. Since I bought the car used, it may have been the stock filter. Nevertheless, I like the way my car is running now!
Cleans air going into the car and comes in a really nice box.
So far so good.
My Car: 2015 STI.
I was in need of a new filter and didn't want to upgrade the whole intake system yet so I started looking into drop ins. I scoured many sites and forums looking for the best one and this is what I discovered:
A. From what I have seen you don't want an oiled filter as it can cause MAF issues. Which leaves dry filter elements like the HKS Super Hybrid.
2. I saw many dyno comparisons and it seems like all of the aftermarket drop in filters will produce about 5 HP.
Personally, I wanted to try a new filter to see if I could get any more sound out of it. I don't think this is something you should do if you are looking for power, but it does help the car breathe. It should be noted that when I did take the stock filter out, it was absolutely filthy. So for what its worth, I think it did its job very well, but also kind of demonstrated how much debris can actually hit the filter of these cars (my first STI).
As far as sound, don't expect too much. In the higher ranges of the RPMs it seems like I can hear a bit more of the turbo and its accessory parts but any other sound its potentially making is muted by the exhaust.
At this point, a few weeks into it, I have no reason to not recommend this product. I kind of like the 3 different foam layers and I am interested to see how well it works, I will try to update this in the future with pictures. Install was easy and it fit in the intake housing very well, no wiggle room for crap to sneak by.
Performance notes: A few days prior to the intake showing up I installed Invidia N1 exhaust. After installing the new filter I noticed my "Peak PSI" jumped from about 17.0 to 18.1. Not sure if this is because of the combination of mods, climate/driving conditions or just the new filter, but it seemed worth noting in the review.
Hope this helps!
