AIR FILTERS - CHANGING
Probably no other single maintenance change to an engine has a greater effect on an engine than changing a dirty air filter. Lamborghini engines suck in a lot of air! If this air flow is impeded with a clogged filter performance suffers greatly. Fortunately Lamborghini has designed their cars so that replacing an air filter is simple to do.
I will describe the changing of filters Figure 1 on a 6.0L Diablo. The process is much the same for all recent cars. There are two identical air filters feeding the engine of these cars. First one needs a "Toro" wrench to open the four screws that hold the air filter cover to the air box. This wrench is shown in Figure 2 below. They can be got at most hardware stores. An Allen wrench can also be used but the fit is not as good. Figure 3 shows the screws being removed. Next the flexible hose attaching the air filter box to the engine needs to be removed. This is done by opening the large hose clamp shown in Figure 4. Figure 5 shows the hose removed.
The old air filter Figure 6, is then removed from the air filter box. Figure 7 shows a typical old filter. Note the black dist between the paper seams. For a 6.0L Diablo (and the 1998 and later Diablo's) the Italian UFI replacement filter is #30-888-00 Figure 8. Earlier cars take a different (smaller) filter. The reusable oil based K&N filter equivalent is #33-2574 for Diablo's (and Murcielago’s). Figure 9 shows the old and new filters side by side on the ground. Figure 10 shows the new filter in the filter box before the cover is put back on the air filter box. The filter should fit in snug with no air gaps around the sides. The only thing to watch in putting everything back together is to make sure the air hose around the engine air intake is snug and even all around the intake before tightening up the hose clamp. Use a small mirror as shown in Figure 11 to make sure there are no air gaps.
The filter assembly on the driver side of the car is the same as on the passenger side. The only difference is that there is a hose attached to the intake hose duct on this side. Make sure the hose is tight when done Figure 12. It is essential that there are no air leaks into the air intake of the engine. All air must go through the air filters. Failure to do this will let get grit etc. into the cylinders and ruin them.
