Details

Keep your car cabin cool during track days with the Flow Designs Australia window vents! These window vents provide much needed air circulation during warmer weather, and are a much more solid construction and safer than any standard window vents available. 

Included are rubber seals to prevent any vibrations and grips tight to your BMW F20 M135/M140 1 Series window so it is secure to drive with at speed. Our team has ensured the window vents do not allow for any baffling wind noise during driving.

Whether you want to keep your cabin cool during track days, or improve the aesthetic of your BMW F20 M135/M140 1 Series, the Flow Designs window vents are the best option currently on the market!

Rubber seals: please note the rubber seals are a very tight fit. To make the install process easier, soak the seals in warm water to create more flexibility. Once installed the rubber will shrink back for tight fitment. We have developed this tight fitment for the following benefits:

  • less vibrations at speed and idle.
  • eliminate baffling noises.
  • to protect your windows and tint from scratching

Effective temporary fix
Style: 18oz, Style: 18oz
The slim brand has always been an genuine effective fix. I have been using slime since I used to ride on bicycles. Well it is not a permanent fix for if you have a hole in your inner tube it is a great fix to hold you over until you are able to get to either the mechanic or to your local store to get a replacement inner tube. Overall, it's worth every penny and you get plenty in the canister that it comes in depending on which slime you are getting whether that's the plastic bottle for your inner tubes for a bicycle or the metal canister as I've shown in my picture for your SUVs trucks or vans. However I don't give this an entire five stars but more of four stars not because of their product but because resorting to using slime rather than fixing the problem is more of my own problem. ⭐⭐⭐⭐ 👍👍

Don't buy doesn't work
Style: 18oz, Style: 18oz
Terrible did nothing. Even tried to let wheel turn 360 degrees yet the solution get in the tire leak proper. Directions on can differ from instructions on here/Amazon. I followed directions on can EXACTLY and still didnt even hold one PSI of air. I'd be better off burning the $10 for warmth rather then waste it this way

Amazing stuff
Style: 14oz
I’ve been using this stuff for a number of years for a number of vehicles now and it works every time. It’s especially great with those small annoying leaks where you just lose a couple pounds every few days so you have to keep adding air like once a week. It totally seals it. The bottle says to only rely on it for 300 to 500 miles and then get a proper fix. However, I have not found this to be the case. The seal holds for the rest of the life of my tire every time I’ve used it. My only complaint is that I wish it was a little cheaper, but you can seal up 2 tires (use only half the can per tire - you can probably even get away with using less). There is a garage not far from me that fixes leaking tires for $10, which is the same price as this product so not really saving any money by using it. It’s more just a matter of convenience. Just make sure you get this “thru-core” one. They have other ones as well so it can get confusing, but the one you’d want for situations like I’ve described above (small to medium leak in a typical passenger vehicle) is this “thru-core” one.

Saved the day, even at 25°
Style: 18oz
The tire tread was peeling off the tire causing a leak that could not be plugged. Completely flat. It was about 25° outside and the can only dispensed half the contents. Was able to inflate the tire and make it to the shop. So the slime saved the day.
