Collars are no longer available. The entire product line has been
discontinued by the manufacturer.
has introduced a new item (this item is no longer available) that will improve cooling on almost any engine that has an
external oil filterit is one of those products that makes you say, Why
didnt I think of that? The
Cool Collar is a finned aluminum jacket that slips over the oil filter (Figure 1). It is secured by a clamp to the outside of the
filter, which provides full surface contact and allows maximum heat transfer. Considering that all of the oil in your Porsche
goes through the filter more than once a minute at freeway speeds, the oil filter is an
excellent location to add cooling capacity. Bench
tests, as well as road tests on both water- and air-cooled engines, have demonstrated oil
temperature reduction of 18 to 23 degrees with the Cool Collar. This is a tremendous cooling improvement for a
very small expenditure, and a few minutes work.
At first look, it appears that the Cool
Collar cannot be installed with the AC compressor in place (Figure 2). However, the installation is very easy. Remove the clamp from the Cool Collar, and place
the split in the collar over the top AC hose (Figure 3). Now rotate the collar, and pull it downward off
the hose into the open space next to the oil filter (Figure 4). Slip the collar onto the oil filter, and push it
until it seats against the filter mount (Figure 5). Secure the collar with the clamp provided, and you
are done (Figure 6). Be
prepared for hot weather, high-performance driving, and prolong the life of your engine. Also be prepared for some
whatthehellisthat questions whenever you open the engine compartment.
