The OEM charge-air-cooler manifold for the B58 engine is adequate in cars with little or no modifications. However, it starts to really its weaknesses in cars that have bolt-on modifications, turbo upgrades, increased fueling (such as port injection), and performance tuning. In addition, the OEM intercooler system has been known to suffer from heat soak in demanding racing conditions such as time attack, endurance racing, drag racing, and drifting, as well as spirited driving on the street. This can cause the car to pull timing out of the engine due to high intake air temperatures (IATs). This can send the car into "limp mode" once temperatures reach a certain threshold. In high boost applications the OEM manifold is also prone to failing at the crimp on gasket joining of the core and tanks.This Part Fits:

Packaging is most disappointing
Color: Black
Giving a 3-star at the moment because I just received the watch and usually comment on a new collection addition after about a week.
•biggest turn off and cause for 3 star upon receipt is because of packaging. The main box seemed already used and returned or carelessly handled & very basic. How it's advertised & described as well as the image seller portrays of the product, the packaging fails at "luxury" depiction.
•Link removal tool is very basic but this was a $23.00 watch. Because I am a collector I knew to pay attention to how pins are removed and had no problems removing the 4 links required to meet my desired size.
•A few reviews said it's heavy and I'm used to pretty heavy + 44-48mm bezels so to my standards, I wouldn't 100% say it feels cheap(i mean c'mon it is so can't be too judgemental) but it slightly does feel "toyish"
•Bracelet out the package even with plastic all over, came with two dot sized blemishes i keep focusing on and upset at.
•Many reviews said after two hours, the time isn't accurate; thus far, time is fine
•A few reviews said the double clasp is weak. 1 time it did loose but after removing links, ive done a lot of shaking and wrist action to test the clasps and nothing so far to match others experience
•It has a nice appearance, can pass for business and casual
•For a $26.00 watch after taxes I'm not disappointed as of yet besides the blemishes and packaging but will revisit in a week or so.
•I read that the date doesn't keep accurately so I will update review after a trial period
• I will say, if you dress correctly with this piece, I feel it has potential to draw attention from it's design

All time favorite watch
This watch is amazing for the price. I have had mine for 5 years or so and I wear it regularly. It's very comfortable resin strap. The design of the face is I think stunningly beautiful. Yes that is a bit strong for a $25 watch but the way the globe pops out, the legibility on par with a high priced dive watch and the funcationality of a timer, stop watch, world time and a data bank you will never use, but still.. cool watch!

Handy
Very easy for old eyes to read, can even see the date if light is good. Light weight for a largish watch. Seems rugged enough for me and the price is right for a beater watch.
