Q 1. How often should I clean the CAI Filter, it will compelet now 10 months in my S2k.

Q 2. Can I clean the A/C filter OR should I only change it.


Thanks,,

 

1. The main determinant would be the conditions under which your car is driven. Is it dusty and dirty a lot? What's you annual mileage?
If it's not terribly dusty where you drive, perhaps an annual inspection would be wise. Clean if you find the filter visibly dirty. I would suggest every year or 10K to 15K miles for the AEM air filter.

2. The "hepa" filter is another story. Check it annually. Because it's a "micron" type of filter, you may need to replace it if you need it to filter the fine particles. But then, this is a convertible and most people really don't need it as a micron filter. Do you use the fan with the top up and windows closed a lot? A new filter would make the system run at top efficiency. I don't care about the fine filtration, so for the first time after about 3 years, I took the thing out, looked at it and used a stiff brush and swept the large debris off it and put it back. As long as the fan works well enough to blow air nicely in the hot of summer and in the cold of winter, I'm good. If you need more that this, get a new filter.
