Ok, I just istalled a Code 3 "Performance Intake." I had already purchased it before the DIY was posted. At first glance, it looks like a nice product; however, there are some issues. I hope Code 3 takes some of this criticism and uses it for improvements to their products.

For one, $150 is a lot of money for what you get. They must be making a gigantic profit. Ok, enough with the assumptions.

The filter is fairly thin and when held up to the light, has some fairly troubling passages. This thing looks like it will pass grains of sand! Foam filters are fine when there are several layers of the material.

The holes weren't drilled large enough. I had to drill the holes slightly larger because the screws were screwing themselves into the filter screen frames and then wouldn't turn any further into the intake base.

No instructions were provided. It's not rocket science, but it might be nice to include some sort of instructions for someone who may not have experience working on their car.

Be careful! Before installing, make sure you clean all the burrs and tiny pieces of plastic from the throttle body side of the intake plate. Mine was full of tiny, loose, slivers of plastic from the cutting process. This should be taken care of prior to shipment.

Lastly, my biggest problem with this thing:
The surface that mates to the intake plenum is flat unlike the diverter plate surface, which has a small lip that fits into the gasket channel of the plenum. With the Code 3 intake, the gasket is useless. It sits flush in the gasket channel and does not contact the intake plate surface. Because of this, there is a possibility of debris getting through the interface gap. I sealed it with a light layer of black silicone, but I'm still not confident in its ability to keep dirt out of the engine.

It's a good idea, but it needs some work. I'm going to sell it if anyone wants it. $100.00

Not bashing, just sharing my opinion.
