Overview:
The APR Coolant Performance System (CPS) is a massive front-mounted cooler upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! It is 140% larger than the stock B8 unit and features a self-bleeding cooling circuit to ensure it is always operating at peak performance. The system is easy to maintain and fully integrated into the factory cooling circuit. This upgrade is highly recommended at every stage!
Features:
- Dramatically lowers intake air temp (IAT)
- Increases and retains HP while minimizing power-robbing heat soak!
- Massive frontal surface area (core) and volume (radiator)
- 29" x 05.5" x 2.1" - 159.5"² & 054"³ - OEM
- 22" x 17.4" x 1.7" - 382.8"² & 130"³ - APR
- Highly effective dual-pass core design
- Tightly packed external louvered fins rapidly dissipate heat as coolant flows through internal cooling paths.
- Self-bleeding and self-optimizing system
- Air-bubbles trapped within the system kills performance!
- The self-bleeding system constantly removes air from the system, without any manual intervention!
- Retains factory safety and control
- The ECU retains full control over the system, protecting against pump failure and coolant leaks.
- Easy to install and maintain
- All the performance without the headaches. Each system is fully pressure tested after assembly.

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days.
The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.
