We’re proud to launch our front mount chargecooler radiator upgrade aimed at BMW B58 models for fast road or track use.

The Issue
As the performance of chargecooled-engines depends on the temperature of the coolant inside the system, it’s very important to ensure it runs as cool as possible for as long as possible. As the standard system can struggle to maintain temperature, especially on a tuned application, the keys to ensuring a consistently lower running temperature are to increase the capacity of the system and its ability to cool it.

The Solution
AIRTEC Motorsport’s solution to improving the original set up with the limited space available behind the bumper to make it any wider or taller was to instead extend it forwards by introducing a core that’s nearly 60mm thicker, at 90mm in depth. This allowed the use of a triple pass core design to allow the coolant to pass through the radiator three times before it exits, with capacity increased to a huge 23.3 litres, compared to the original 7.7 litres; a gain of 203%.

Despite the huge cooling capacity increase that allows the chargecooler system to run cooler for longer, the radiator fits neatly behind the bumper and requires no modifications to fit, using the OEM mounts and the original coolant connectors. To protect the larger core in its vulnerable position at the front of the car, there is also a stone guard.

Finished in a high-quality powder-coated black finish, the comprehensive fitting kit includes all fixtures and a detailed instruction fitting guide.

Pups love these sneakers
Color: Squirrels (3-pack)
My pups really enjoy these toys—they love the squeakers and stay entertained chasing them around. Perfect size for small dogs and puppies, and they’re soft enough for indoor play. The only downside is they don’t hold up forever with heavy chewing, but for the price and fun factor, they’re definitely worth it.

Good for a small to medium dog
Color: Squirrels (3-pack)
These replacement ones were bigger than anticipated but work well for my small dog. Pretty durable (and she likes to destroy toys)

Perfect Toy for the Picky Dogs!
Color: Squirrels (3-pack)
These are replacement squirrels. I had these for my own dogs. When I noticed how much enjoyment they got out of them, I purchased them as gifts. My brother’s 20 lb dog is so picky, but I took a chance. The squirrel toys are the only ones he plays with. According to my brother, his dog ignores treats and toys, but loves the squirrels. A friend of mine said the same thing. She also has small dogs, 25 lb & 30 lb. They preferred the squirrels. This toy is not for big dogs. Unless they’re gentle, they will probably be torn apart very quickly. They are very easy to chew on, the squeak isn’t loud, there’s no smell and very entertaining!

The toys are soft but well made, and my dog really likes that they squeak. He loves carrying them around and hunting for them when I hide them.
