The 'Open-Air-Box' system gives you the abundance and unrestricted 360° of air source compared to OEM's sealed airbox with a flat filter and tube-fed air source. During R&D, we installed temperature probes around the engine compartment and the gauge showed the inside temperature matched the ambient after vehicle speed past 20 mph. And by logging the Mass Air Flow (MAF) sensor also showed that open-air-box intake generated a higher volume (gr/sec) of air going through the sensor. So when we had to choose between (a) cooler air at all speed with a limited air source, vs. (b) cooler air at 20~ mph. with an unlimited air source, the choice was pretty obvious.

Also included pre-oiled and cleanable filter. Please click here for more info on the cleaning kit. 

MINI did a great job on the 2011 model MCS in improving the turbo intake tube by replacing the soft rubber tubing with a full-size and rigid ABS plastic one, similar to NM's aluminum/silicone version that we offer for the 2007~2010 MCS & JCW vehicles. So we decided to leave the inlet tube out and price out the kit to be more economical.

C.A.R.B. Exempt! EO# D-236-22

Notes:

Due to the ECU change, we came up with a different bracket that holds the fresh air inlet pipe. Please see below for the production breakdown.

2007 - 2012 (March Production): Use part number NM.658857
2012 (April Production) - up: Use part number NM.658857.1
If you purchase this kit prior to December 2012 for your post-April '12 production Mini, please email or call us (805.388.7171) and we will send you the updated bracket for FREE!

For those who do not want to deal with periodical filter cleaning, a dry paper filter is an option. Made using the same paper material as the factory panel filters, designed to be thrown away once dirty. Same performance and price as the oiled filter. Make sure to choose the part number that ends with (D) for the dry filter kit.

Stunning Gentleman's Watch
Color: Grey
This is my second Tissot watch. It's quite stunning in person. The online photos don't do it justice. It has the look and feel of a much more expensive gentleman's watch which makes this purchase a great bargain. Tissot is a great reliable Swiss made watch brand. My first Tissot watch which is probably more than 20 years old still runs great. Very pleased with this purchase.

Good Tissot Watch
Color: Grey
Arrived on time, in its original box, include a 2 year international warranty, into the box include a book with the Tissot brand history in Switzerland. Algo a second book with a whole catalog of Tissot watches men and women. The watch looks better when you put in on your wrist. The “naval” blue really gives the clock a classy look. The stainless steel workmanship is really good, the metal is bright and perfectly polished. The metal wristband quality is very good, did not have any problem to adjust the size , I went to my preferred clock workshop for this job, they extracted a few pieces of the band to fit to my small wrist size. Have to get used to the butterfly latch, but after a few days, now I learned to open and close it without any effort. The clock it’s very accurate, I’ve been using my Tissot for near a month and it just increased a few seconds per week. I do the setup and check accuracy with my pc clock. In short, It”s a good value watch, nice, good looking, accurate.

Class and elegance
Color: Gold
I absolutely love this watch! My grandson also loved mine so I bought him one for Christmas. This is the 4th Citizen watch I have purchased. 2 are ecodrive and 2 are battery powered. I have to say I do like the battery powered watches better for their weight, lots lighter on your wrist than the ecodrive I regularly used to wear. This watch has taken a beating, as it seems like I'm always hitting the face on something, and has performed beautifully. I figured that I would've replaced the crystal by now but I haven't had to. My grandson admired and wanted mine, (I can't part with it because it has special meaning) so I bought him the identical model. I have worn mine in water, extreme cold, and out to dinner. It looks and performs beautifully. This watch is classy, elegant and beautiful and it's not a giant timepiece although you may have to take it to your local jeweler for band sizing. There's videos on u tube but I don't recommend trying that for taking links out. I say beautiful because as a woman wearing this watch it's not overwhelming and screaming look at me I'm wearing a man's watch. However this watch is handsome looking on men, my husband and grandson lol. The band is smooth, doesn't kink or pinch my wrist and when fitted properly it doesn't end up face down or sliding over and staying over on the outside of my wrist. Only drawback for me is I'm not used to the day dial and sometimes when setting the time bc some months are shorter I tend to be a day ahead, easy fix. I've gotten lots of compliments on this watch and would definitely buy it again

5-Star Review: Sleek, Reliable, and Worth Every Penny!
Color: Gold, Color: Gold
I recently purchased this Citizen watch, and I'm thoroughly impressed! The design is sleek and modern, perfect for both casual and formal occasions. The Eco-Drive technology is a game-changer-no battery changes needed, just sunlight or indoor light to keep it running. The build quality feels premium, and the stainless steel band is comfortable yet durable. It keeps time accurately, and the dial is easy to read. For the price, this watch offers exceptional value and style. Highly recommend it to anyone looking for a reliable, eco-friendly timepiece!
