I dynoed the car with the HKS and K&N. The HKS was 6rwhp more and it was run immediately after the K&N so it was probably heat soaked as well so maybe even more hp than that. Also, I thought it filtered very well and the best part was I never had to clean the filter. I just bought the 200mm foam one for $15. I only had to replace it once in three years (but I didn't really drive that much) and you have available color options for grill holding in foam. I had chrome. The adapter was also nice than the litte K&N one. If you do shows where you take the front panel off then it looks nicer also. All this info and all I really cared about was that it made more hp.
