I purchased the 57i MPI Induction Kit for my 1998 Rover Mini. The sound is great and definitely sets my little Mini apart from the rest! With already 45mpg, I didn't buy this kit for the gas mileage, I knew the great products that K&N makes. Definitely more power on the Autobahn, barely getting to 140kph (84mph) before, I can now go 160kph (96mph) easy! Love the product! Thank you!

P.S. I also have pictures of the installed filter and hoses if interested. Thanks again, Mike Watson

I am very familiar with the fine products and performance value K&N delivers. I've used these incredible filters on all of my vehicles (two Jeep, SRT, 8 SUVs and my current 2014 Range Rover Sport 5.0L Supercharged) I can feel the difference.

The k&n air filter added 6 miles to the gallon on my 2008 land rover. I have used the air filters in my last 6 vehicles. I am very pleased with this product.
