Has anyone with an 06 Mini S made the switch from the stock air filter to the drop in K & N air filter replacement ?

Not the cold air type, but using just the stock air filter holder...............

If so, any noticeable changes ?

 

I did some dyno testing long time ago and we gained 3hp with just the drop in filter.

I've got em in stock if you need one.

 

I dropped one in about six months ago... easy enough job, stock one was FILTHY... don't know if it really made much of a difference though.

 

Understand that the K&N will probably get you a few horsepower at the expense of less filtration.

I'm a little wary of K&N's products as the oil in the filter can coat heated-wire type airflow sensors, causing problems.

I'd recommend using either the stock Mahle filters or ITG foam filters.

I find it interesting that K&N is now promoting themselves as a "green" company in print ads, claiming that a re-usable filter is more eco-friendly.

 

so exactly how does a driver 'experience' a 3 HP increase?

come ON people .... don't be dupe'd

I use K&N for the reusable and cleanable factor (green????) but the best is probably a simple paper filter
