2nd Gen R55 Clubman Most liked posts in thread: Stock Clubman S intake or aftermarket intake

For performance, it is hard to beat the stock S intake. Aftermarket cold air intakes add noise but not horsepower.

Use a high flow drop in filter or a JCW air filter set up for best results.

 

I got an ECS CF CAI , yes I paid way too much. But it's the same as having the JCW box and air filter but it looks so bad A$$ .

I had the K&N but it added nothing but sound and heat.

 

JCW cone filter if need be, otherwise drop in panel filter will net same results
