With these items, we are about to create our own Cold Air Intake and let me tell you, much better than K&N current setup, Volant being the best aftermarket in my opinion cant be better than this or anyone’s really, how can they compare?

All pieces required for this custom air intake right here…

Used K&N part number #RC-5060

Disassembly of the stock setup:

Simple flat blade screw driver or 8mm socket on the clamps over the throttle and the MAF.

Remove the intake pipe.

Unplug the MAF.

Using 10mm socket, remove the 3 bolts holding the filter box and remove the entire assembly.

Lets remove the front plastic shield. This has TWO plastic pins and two hooks on either end.

Undo the Three bolts holding the filter box in and remove

Remove the MAF from the box by simply working around the rubber, pulling the MAF out of the box. De-screen if desired (wont get into it if it’s a good idea or not).

Now we have some room… Future home of a D1SC, cant wait.

Doing some rough fitting, the desired length on the aluminum was 9 ¾ “ in length.

Fairly straight forward, the MAF is connected directly to the K&N cone filter.

This gave us a rough idea of where to have the cone shield cut and formed.

Now for the fun part! – Grab your dremmel and your trash can!

Now this actually goes quite easy if a bit of patience is used.

Cut the top rim off and cut the can diagonally (not even) but leaving more on the L side.

This allows enough to cover the area and we can trim to fit later.

I would like to comment on GM’s retarded idea of a ‘Scoop’ rubber heavily mounted and not easily removed out of the bumper without taking everything apart. And the scoop towards the mesh grill faces UP, im guessing to prevent debris from entering, but what the hell…

Start trimming the piece, remembering the plastic cover will need some room when reinstalled.

Cut a hole where clearance between the power steering pump and the radiator fan mount to fit the MAF just. The MAF has holds to bolt up to the shield.

Got some good rubber trim and went around the entire cut plastic trash can.

Notice we clear and take in nice cold air near the fender, on the bottom and that gay looking rubber intake scoop.

Trimming the top requires several attempts closing the hood and checking clearance.

You will know when you have it right as the trim is squished enough just before the hood closes.

Initial tests show that WITH the 90mm throttle, the 92mm FAST intake and the custom intake increased cylinder air mass from 0.64 to 0.76 over 4000rpm. That’s a 11% increase of air over stock. Intake air temps where cut in half and you can clearly tell when you open the hood on a hot motor and stick your hand where the filter is, its nice and cool!

Gotta say, for half the price, looks and functions twice what the pros put out.
