Gilly, I thought I'd start a new post rather than hijack Luxury Addict's.

Ok, so what I've read from other posts here, the K&N contaminates the air flow sensor with oil and this somehow damages it? I've never heard of that before, how does it damage it? I'm guessing the oil coats and insulates the sensor and prevents it from reading temp correctly? I would think a blast of brake cleaner would take care of that? Shoot, let me know because I have one on my car and I was just about to buy one for another.

Thanks!
