Just finished my test drive after removing the filters:
This may be perceived, but it's what I "think" I noticed.
No noticeable difference in sound, either intake or exhaust. Seemed to have a much more sensitive throttle response. At acceleration from a stop, seemed to have a little more "pep" and snappiness to it.
Hard acceleration from 0-90 MPH, the car felt noticeablely quicker, and did seem to have a cleaner exhaust note.
I reset my MPG meter and seemed to notice a slight increase in mileage. I ran about 27 miles in all.
So, to sound like a K&N air filter ad: More hp, more MPG, more breathability.
Overall the engine just seemed to breathe easier.
Now, I have a question for the experts: If even a tiny piece of plastic shaving got sucked into the engine, will that cause any damage? I cleaned the inside of the housing as thouroughly as I could and tried to make sure there were no plastic shavings (that scrape off when removing the clips), and even used my air compressor to get anything else remaining in there. That has been my only concern is that something, however small, might get sucked into the engine. Please advise. THANKS!
