As many of you know, I had my BMC filters installed when my Kelleners Motor Kit was installed over one year ago. In the fall I installed RPI scoops and realized some gains when I ran the car with my vBox.
Over the past few weeks I noticed the power doesn't seem to be what it used to be and I realized that RPMs seem to fluctuate at idle occasionally. I thought it might be time to check the cleanliness of my filters, so after a couple minutes I removed them and realized it was the filters! They were really dirty. I SPECULATE that with the scoops installed and me driving my car in all weather conditions, I might have consumed a lot of dirty mist from rainy road conditions where it might not have been consumed otherwise. I tapped the filters out on a white shop towel and the white of the shop towel turned to black. These things were DIRTY. I didn't have a cleaning kit, so I just did the best I could shaking out the filters and picking the dead bugs out of the pleats. Moments after firing up the car with the half-a$$ed cleaned filters and driving off, increased performance was immediately noticeable.
So, one week ago I ordered a BMC filter kit, cleaned them and oiled them per the instructions. After putting them in the car, performance dropped off dramatically. It felt as if the car was stuck in P400 mode. I figured I overoiled them. So, once again I have them out, cleaned them with the detergent, but it seems the detergent that comes with the cleaning kit doesn't do the job of removing all the oil. So I have cleaned them again using a super diluted mixture of dawn dishwashing detergent to break up the oil and get the things cleaned. It worked. I'm going to lightly mist the filters with the oil this time instead of what the instructions recommend. Otherwise, I'll order another set of filters.
Has anyone else out there had problems cleaning and re-oiling your filters? Are there any recommended techniques to getting these things back to the original performance status without buying a new set? I'll update with my results and/or decision to get a new set. Oh well, I guess it's a cheap solution to just buy a new set if this doesn't work.
