      Review & Installation Video

      Hey everyone I’m Justin with and I’m taking a look at an engine bay dress up item for your ride. I’m referring to this brushed stainless steel radiator cover for all 99-04 Mustang GTs and all 99-01 Cobras. Let’s face it your factory rad cover isn’t going to get you any compliments when you pop your hood, chances are its old, dirty and could probably use a little TLC, that TLC comes in the form of this quality brushed stainless steel rad cover that will instantly become the star of your bay. This cover is made from 100% stainless steel and features a brushed satin finish that’s sure to make a nice addition to any engine compartment. In addition it’s stamped to factory making it a perfect fit as you can see in the GT behind me. Installation is pretty straight forward, using a flat head screwdriver go ahead and pop out the plastic retainer clips holding your factory radiator cover and grill in place after that reinstall the new stainless steel radiator cover using the new hardware and that’s it. It shouldn’t take you any more than a half hour. Whether you are just beginning to mod your ride or your well on your way to full on show car status this brushed aluminum radiator cover is sure to take care of an often neglected spot in your engine bay that will win you some points with the judges, or your buddies next time you pop your hood, check it out.

        3 2001 GT - 17stangox Installation Time: Afternoon

        Looks good, horrible fitment

        This does look great under he hood, a lot better than OEM, however, it has serious fitment issues. The first one I had to send back because the holes were not cut right and they didn’t even come close to lining up, the second one did not have the same issue, but it was still exceedingly difficult to get on, they need to shift the placement of their holes and slots for the screws and for the rad overflow in order for this to fit right, I had to expand the slots for the rad overflow myself to get it all lined up. And my car is straight as an arrow, never been in an accident.

        Cover plate for 99 Cobra SVT

        The fit had to be adjusted as the front edge was too far out in front of the headlight support panel. Required to be bent back further for the two holes to align with the panel.

        Radiator cover

        I am very disappointed in this product because it is very cheaply made and does not fit my 2001 GT. It is very poorly designed and simply looks terrible on my car. I am planning on return it and hope I can get credit for a poor buy

      Hi can you make a radiator cover with the terminator logo or engraving and how much is the cost is a 2004 cobra terminator thanks I'll wait for you answer

      This can't be all that different to not fit a 1998 Cobra... Can it? Is it mounting points that are different or what? Thinking it may be possible to modify to fit.

      • There are mounting positions and clearance issues that prevent fitment with models other than those listed.

      So what is keeping this from working on a 03/04 Cobra? I assume the factory intercooler reservoir is the issue but it would work with say a trunk mounted reservoir.

      • The Modern Billet Brushed Stainless Steel Radiator Cover will not work with the 2003-2004 Cobras as it does not have holes for the Supercharger Coolant Tank.

      I was wondering if this would fit in a 04 svt cobra convertible.

      • This would not be a good fit on an 04 SVT cobra convertible or coupe.
