Complete breather kit for the Mk4 GTi/Jetta 1.8T, fully bolt in for stock application and fully modified cars. Neatly replaced the relay cluster mounted on the drivers side fire wall (adjacent to where the engine harness comes over the firewall), a direct bolt in no modifications required. 034 part number - 034-101-1003
Kit features:
- 034Motorsport custom baffled Vortex breather can, this design can is used in aircraft and motorsport applications to remove oil and water vapor from the crank case fumes. As crank case fumes are forced out, they enter the catch can tangentially, through centrifugal force causing heavier oil and water vapor to fling outward and drain down the walls of the can. This is a much more effective way of seperating oil and water vapor than most generic "catch cans"
- Full draining back to the block so the can never has to be drained, a 034Motorsport oil drain flange mounts between the oil pan and the turbo oil drain line to allow seperated oil to drain back to the sump.
- Molded reinforced silicone hoses for lifelong use and durability, large diameter hoses ensure restriction free crank case ventilation, catch can features 1" fittings for high flow.
- Full recirculation back into the intake for smog compliance, or can be implimented with an air filter on the catch can outlet to keep any oil fumes out of the intake system. Choose option below.
- All clamps, fittings and hardware required to install the kit in virtually any Mk4 VW 1.8t.
- **Optionally ADD a matching Silicone Lower Block Breather Hose to compliment this kit for an all Silicone breather hose setup!

It's thin but it's good for cooler mornings and windy days
This jacket is not super thick or sherpa/fleece lined. But it's great for cooler temperatures, windy days, or staying warm while out on a boat. It's lightweight, cuts the wind and is great for layering. Folding it into the bag makes it ideal for travel and camping

Okay for the price
Size: XX-Large, Color: Denim Blue
The product was light and compact for packing for an Alaska cruise. It was also sufficiently warm and relatively rain resistant. But on the second day of wearing, the zipper blew out. I was able to fix for a short while, but in the end, I couldn’t use it.

Great deal on a shacket
Color: Khaki, Size: X-Large
The shacket looks like it is depicted in pictures. It is oversized in general since it is intended to be an over garment. The weight of the cotton is heavier than a normal cotton shirt, but not as heavy as a denim jacket.
I am 5'8" tall and 175 pounds. My sport coat chest measurement is 44 inches. I ordered XL so it would be large enough to cover a T shirt and shoulder holster for S&W Shield to CCW. I washed in cold and hung dried, and it still feels a little too large. I will try to wash and machine dry and see if the fit improved.
The shacket looks to be worn with sleeves extended. I tried rolling up the sleeves and was only able to get two rolls. A third roll was not possible because it wouldn't fit around my forearms even though I'm not muscular. Those wanting to roll up their sleeves may need to alter the shacket.
I was pleasantly surprised that the shacket did not have a chemical smell, which makes sense because it is 100% cotton. It instead smelled like cotton.
After the first wash I didn't notice any imperfections. The buttons don't seem to be unraveling, and the other stitching looks to be holding. The shacket comes with one extra button.
Overall, it looks like a nice shacket. Because it comes from China, I was expecting a stinky, plastic shirt notwithstanding the advertising. But no, it looks like it's all cotton, all quite clean and healthy.
For the price, it looks like a great deal. Note that they can't fit all body types. If you're muscular with large arms and shoulders, I would expect the usual difficulty in finding a fit.

Good quality, runs small through middle
Color: Nave Blue, Size: 3X-Large
Good looking shirt and much thicker and sturdier than I expected. Run small in gut though. I'm a 3X in everything but had to get 4X in this.

Great overshirt, but heavier than you might expect.
Great fit. Good quality, heavy cotton. I bought it as a substitute for a light jacket… to maybe wear open with a t-shirt. It’s pretty heavy… almost like denim… which was what I wanted. But it’s heavier than what I would wear as a “shirt”. The price was great, so I’d buy it again since it comes in a variety of colors.
