This Mace ETC and K&N's air filter have been put together to meet the performance upgrade requirements of BMW 3 series I4 engines.

It is washable and reusable and is custom designed to fit into your existing factory air box. This filter lasts up to 80,000km before cleaning is required depending upon driving conditions. It comes with K&N million mile limited warranty and it will not void vehicle warranty.

  • Sport Mode: 9 stages of increased accelerator response suited for spirited driving.

Great for small projects. Nice fit.
I purchased this set while building a couple of end tables. They fit like a glove and it's really nice that they come with the hole saw bit. It's a great set for what you get.

Includes everything you need and a bonus to get the cord wrap
I bought this to route the cords up to the monitor on a height-adjustable desk. The top of the desk is an inch thick, and this was easy to drill through. To make sure I got a clean cut and did not damage the top, I put painters' tape on the area where I wanted to cut and drilled a small starter hole to get it exactly in the right spot. It cut a really clean hole from the top, and the plastic insert fit perfectly. Once I got the hole cut and the wires run where I wanted them, I put the cord wrap on. The tool that comes with the cord wrap is really slick and super easy to use. I was able to bundle together three cords that hang off the side of the desk. Given that the desk is adjustable, it was a nice bonus to get the cord manager with the kit, as it keeps the cords from getting hung up in the desk when adjusting it. I'm very happy with the purchase, great price.

Good product
The hole covers are great. As far as the hole cutting bit. Not so much. But still worth the price.
