I have a questions about the K&N filter location.
1. How often it has to be clean? K&N says 50k miles, but at this application filter is so low, and unprotected, so maybe it requires cleaning more often?
2. Is it safe to drive the car in heavy rain? What happen if someone hits big pool of water on the driveway? Is it possible to suck it to the manifolds?
3. Does it make sense to clean it with air gun blower between regular washings? Will that help, or rather the quite opposite thing will happen?
And unrelated question. How much will cost to upgrade from VT2-575 to 625, or 650?
