A. We have found that this is not necessary because: 1) large objects cannot fall through the louvered openings, and the flow of air and heat is out, not in, and 2) anything in the way of the heatflow/airflow provides resistance and slows it down. HOWEVER, for some reason, some people feel compelled to have [...]
A. The Instructions tell you how to place a single row of black electrical tape on the underside of each Hood Louver, as a cushion. This is all that is needed. If a thicker gasket, were used, the hood temps and the frequent cycling effect (hot to cold and cold to hot) would cause it [...]
 On Using Screws, Instead of Rivets Some owners ask us about using sheet metal screws, rather than the rivets. To avoid rust (the scourge of car guys), be sure to buy Stainless Steel screws. Also, select Phillips-Head, Pan-Head Screws, as they look better. You can use ½†length or â…œâ€(better). The No. 6 diameter fit [...]
Consider this: Most of our Hood Louvers can be shortened (front-to-rear) by trimming off the panel from the rear, parallel to the louvered openings. Then, you can: 1) Drill rivet holes in the remaining web behind the rear of the last louvered opening, or 2) do not place any rivets across the rear of the [...]

WHEN SELECTING HOOD LOUVER SIZE. . . DON’T LOOK AT THE UNDER-HOOD FRAME AND JUDGE FROM THAT! With your hood open, look at the interior Hood support frame. IT IS COMPLETELY SATISFACTORY TO HAVE SOME OF THE HOOD FRAME PASSING UNDER THE HOOD LOUVERS. If so, you can “hold out†or “Swiss Cheese†the hood [...]
UNDERHOOD HEAT – IT KEEPS GETTING WORSE!!! HERE’S WHY. It’s gotten SO hot under the hood, BMW/MINIS have gone to putting a fan on the steering pump, and some Range Rovers have a water-cooled alternator! Crazy! The problems are: 1) Heat is the MORTAL ENEMY of your engine. The higher the temp, the faster engine [...]
