This thread reminds me to service the K&N air filter on my "Maggie" soon. After 10 years, it's going to roll to 100,000 miles this spring so it will need that service for the 2nd time since I bought the filter for $35 in when the car was new. Here's a pic last month...

I know opinions vary on these like the engine oil threads, so to each their own. They work for me with zero problems and 1 recharge kit purchased in the last 10 years among 3 cars. Mind you, I don't live in a dusty area.
