BMW 135i – BMS Dual Cone Intake Install (N54)

Last week, I scored a used BMS Dual Cone Intake kit on 1Addicts for only $25 shipped! It was just too good of a price to pass up. When I opened the box, I found a pair of very dirty white filters. I regret not taking pictures of them because they almost looked black.

After soaking them with degreaser and rising them off, they looked brand new again! A couple minutes in the sun and they were dry. Then I grabbed a can of K&N filter oil and sprayed a nice coat on top. To my surprise, the oil was red! My precious white filters were no longer white! Oh well… they still look great.

BMS claims that these puppies add at least 15HP to the wheels. I’m not sure how accurate that is but the sound is intoxicating! I had no problems with the K&N panel filter in the OEM airbox, but I read that it can be restrictive at higher boost levels. For only $25, I couldn’t go wrong with these. A quick test run proved that the car pulls great and sounds much better. Plus, I like the look of these under the hood.
