Improve the cooling capacity on your 2015-2020 BMW M3 or M4 with the Mishimoto Performance Heat Exchanger. Air-to-water intercooling is the means of more efficient heat transfer from the charged air, but it now requires an additional heat exchanger mounted to the front of the vehicle in order to dissipate the transferred heat. The S55 powering the F8X generation of the M?s packs quite a punch and while the BMW engineers laid a solid foundation for dissipating the heat from the intercooling system, but we saw some room to improve. We started by eliminating any bits of plastic from the design, and replacing the end tanks, and ports with durable aluminum. We kept the dual-pass flow through the core for maximum cooling properties, while expanding the core into the available space. Our new design features a 42mm thick core while extending the height by 150mm totaling in a 60-percent increase in core volume and adding 180-percent to the external fin surface area. The end result of our improvements is a 9 F drop in global intercooling system temperatures over the stock unit. Size isn?t the only thing that matters with this heat exchanger. Since the heat exchanger sits front and center in the M3 and M4?s cooling stack, It's susceptible to damage from road debris. To keep your air-to-water system safe, our heat exchanger comes equipped with a steel mesh stone guard for an added layer of protection for the fins. We also incorporated a variable fin pitch for the lower 12 rows on the core in order to facilitate cooling to DCT equipped M?s. Finally, our 2015-2020 BMW F8X M3/M4 Performance Heat Exchanger also includes the Mishimoto Lifetime Warranty for a worry-free install.This Part Fits:

Worked on slow leak… one month already!!!
Style: 18oz
Edit: Still holding proper pressure at 2-months !!!
Had a slow leak where my tire went from 44psi to ~18psi over 2-3 days… Dashboard light would let me know every few days that I had a tire problem and I would inflate the tire back up to 44psi… Anyway, I used this product and filled air back to 44 psi and it’s held the pressure for a month already !!!! Be sure to deflate tire to ~15 PSI before adding the product… it only took about 30 seconds to empty the container into my tire with the tire pressure low. Very happy with this product !!!

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.
