Good easy filter. I liked how you could have the hole offset on it.
I bought this filter (21-203DOSK) to replace my oiled filter that originally came with my intake. I like this filter's performance and think dry flow is the only way to go. I didn't know this filter was offset but, it ended up helping my application. I'm using this filter on my 2007 Audi A3 2.0TFSI engine.
