I am taking my truck in on monday to get rustproofed. Just one of the many plusses of living with salty winter roads. I have an AFE open style CAI. I started wondering about when the truck gets sprayed under the hood and the oil they use hitting my air filter. Now I am thinking that might create problems. I have read about some members having problems with their intakes and MAF sensors having problems and now I am wondering if maybe I should bag the filter just before it gets sprayed. I would hate for the oil they use to somehow damage the filter or gum up the MAF sensor. I know I can tell the guy to be carefull around the filter but there is still the chance that oil can drip onto the filter or get sucked into the intake once I drive away.
Has anyone ever heard of problems like this before or do I even need to worry about this?

Anyone out there???

If there's enough concern to think about doing something, do it. It can't hurt to put a bag on but it can hurt not to.

I'd bag the filter. I over-oiled my K&N once, it cost me dearly for a new MAF sensor:(

I did bag it before spraying just to be safe. Just never heard if anyone ever ran into this before or had a problem with oil spray getting on their filter.
