We then cut a 2.5 inch long piece of 3 inch diameter PVC pipe.

 

And then stuck in the top. The reason for this is so that it would hook into the piece that is in the engine bay itself, which you will see in the next two photos.

 

Here is the first photo. This hole is normally where the OEM intake resonator goes through.

 

Another shot. The area to the right of the tube where light is coming through is where air normally enters stock RX300s on its way to the air box and of course eventually the engine.

 

Looking through the hole in the bumper before the mini-bullhorns are attached.

 

A close peak of the 45 degree angle, which is an improvement over the 90 degree angle that was here on the last version of this piece.

That bracket you see on the left is what normally holds the OEM air intake resonator.

 

One more shot looking up and again you can see that bracket that holds the resonator.

 

Loading in the mini-bullhorns.

 

Another shot and you can notice a little light coming in...this will bring me to an important point shortly.

 

This is looking through the front bumper hold and notice how the two mini-bullhorns aren't flush on the rear of the bumper hole but put further back. You want to allow some spacing so as not to build up pressure on the front. I did this when I had the big bullhorn and I also added three little holes on the back of the 90 degree turn going upward. If you go page 6 of my car domain page you may remember that I called these pressure holes, though in this case I have sufficient space as to not need this, but I still allow for air to get by somewhat.

 

From the front and you will notice a small air gap between the two mini-bullhorns and this is okay to prevent too much pressure from building up.

 

Final shot and you can better notice how these mini-bullhorns capture more of the air than the last modification which was just two 3 inch diameter pipes, but here it goes from a combined 6 inch diameter to an 8 inch diameter with the two.

On my tests on the highway here from a dead start you can definitely feel on the low end the air at your feet. It does not feel like a sponge where the air slowly gathers momentum, the air rams right in there.

I still need to test this on the track and hopefully the rainy weather right now clears.
