Wagner Tuning Intercooler kit vs. OEM RS4 Intercooler:
There are many claims on the internet that the RS4 intercooler are the easiest upgrade for your S4 Intercooler. According to our calculations above, there is a slight increase in performance, but is it worth it?

Below are a few of the issues you will encounter for this modest performance increase:
- The mounting tabs on the RS4 intercooler must be converted to the S4 style, including intercooler piping mounting differences.
- After you have installed the RS4 units, the engine will need to be modified to fit, as the RS4 Intercooler extend further out and cut into the cover.
- The S4 bumper must be modified & cut inside to fit RS4 intercooler.

The Choice is Clear - The Wagner Tuning Audi S4 / RS4 B5 Intercooler Kit not only offers higher performance, but easy installation!

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

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.
