it comes with a metal shroud...has big necks, and apparently, the highest tech core material for heat exchange.
There are three versions as described below with info from the web site. The S model is basically a modern, big necked, stock replacement. The straight V4 is probably the one that most use and will handle easily the power that Woody describes, and there is an R model that was designed for a GSCA class that will handle more but is probably completely unnecessary for any stock block.

The V-4S is a direct stock replacement intercooler and utilizes the stock intercooler shroud and the stock mounting bracket. A direct replacement. This unit utilizes our 13-row core matrix, features our exclusive high flow inlet and outlet necks like used on our V-4 and V-4R intercoolers and is powder coated 70% gloss black. Typical gains of 1/10 - 2/10s. If your on a budget and need to replace your stock intercooler, this is the unit for you. During testing at Buicks at Bristol 2000, this went 11.19 @ 120 MPH at Bristol 2000 (high elevation).
V-4S $499 (stock item)
Our V-4 19/21 row stock location intercooler is a direct bolt in that fits with the sway bar. On a low 12 second car, the V-4 will knock a solid 3/10s and 3 MPH off 1/4 mile E.T.s and the 19/21 row has already been well into the 10.6s at 126 MPH+. The 19/21 row V-4 mantains almost the same ground clearance as the OE intercooler with the shroud installed. See the March 2000 and May 2000 issues of GM High Tech Performance for a compelte feature and install on the V-4. Please note, as of January 2001, the 19 row has become a 21 row and the 24 row has become a 27 row as the result of our new core matrix and brazing process. We have seen no measurable difference in performance from the 19 to the 21 or from the 24 to the 27 row.
V-4 Stock Location 21 row intercooler $699 (currently backlogged 3 weeks)
The V-4R 24/27 row model will support up to 750 horsepower and also fits with swaybar.
V-4R Stock Location 27 row intercooler $869 (currently backlogged 3 weeks)
