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:

Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

A Wonderful Update To A Great Old Reference Book!
Format: Hardcover
It's the Merck Manual! If you know medicine but are aware you don't know EVERYTHING about EVERYTHING! (Few if any do!) This is a wonderful reference. If you have no medical knowledge and think this will make you know what doctors know. Don't waste your money. You have to have a basic understanding for this to be helpful. This is a wonderful update to an old favorite.

The most current and inclusive medical reference available mid-2018.
Format: Hardcover, Format: Hardcover
Here’s the review I wrote for the 19th edition on 2011: I've been getting and using the Merck Manual for over 30 years to answer questions about disease for family and friends (pediatrics through geriatrics) as well as preparing to ask germane questions of physicians responsible for care of family and friends. It is comprehensive in its coverage of the etiology, diagnosis, treatment and prognosis of diseases of the human body and contains the latest research results on the treatment options. It's really not that difficult for the layman to understand the medical terminology and the result is factual understanding of the major aspects of disease which you will NOT get from the standard home health care books from Johns Hopkins, Harvard, Mayo Clinic, the AMA or even the Merck Home Health handbook. And, unlike the Merck Manual, these books directed to the laity do not contain the diagnostic information upon which physicians decide precisely what disease they are presented with. Yes, there will be much superfluous information which you may never use, but, when you want and need the information about a specific disease, here's where you should start your education.
The same holds true for the updated 2018 20th edition. I neglected to mention that this manual also contains a plethora of ancillary information including thorough sections on pediatrics, geriatrics, injuries, bites and stings, patient care, alternative medicine, dietary supplements, rehabilitation, normal test values and even legal issues such as advance directives. Yup, it’s pricey, but it’s always proved to be valuable to me.
