HKS drop in filters

6spd · 08-08-2013, 01:27 PM

I installed them a few years ago on my 09. The differences were slight, but still noticeable. Throttle felt about the same, sound increased slightly as revs got higher, and the car felt less choked up at high rpms. Added HPS tubes, no difference.

After that I switched to the Injen intakes, noticed a much better high rpm feeling and response, but the low end throttle suffered. It sounded ok, but just to much like that typical generic "whoosh" sound.

Switch back to all stock for a week or so before trading it in, noticed so much throttle response come back, the sound smoothed out, but the high rpms felt, in a sense, nasty.

No after driving my 13 for a week or so, I'm ready to at least throw some better filters back in. They are a nice compromise between stock and cai's. Best throttle response down low, freer feeling up high, and a nice smooth engine sound.
