DIY: "Cold" Air Intake

DIY: "Cold" Air Intake
Learned a lot from this forum. So wanted to give back to the community. I didnt invent this, the concept and idea was already out there on the threads. I just wrote a DIY for people to see.
Although our intake boxes are open the hood actually closes most of the openings. This is just to improve the stock box. Dont expect significant gains, as this mod will give only minor gains, if any. It will just help open up some more free air. Here's my Rev-up airbox with Z-tube and "Cold" air mod.
1. The basic parts I bought. An Auto Vac hose, Drill bit, and pipe cap. Oh also some black spray paint and Clear since I didnt have any. Best $25 I spent.
2. Remove
3. Remove
4. Loosen or Remove
5. Cut here. Be careful.
6. How it should look.
7. Cut here. Be careful
8. Cut slowly.
9. It should be perfect. Nice and tight, and wont fall off.
10. Thread the hose through.
11. Thread the other end of the hose to the stock air box.
12. It never rains in socal but I bought a cap for those who live in Rainy areas.
13. Perfect time to clean your dirty Air filter.
14. Paint the white ring to black.
15. Also paint the cap if your gonna use it.
16. Finished product. Perfectly hidden.
Like I said, this is only to supplement your stock box. I have no proof of its gains, nor will I do anything try to prove its performance. This is only a DIY.
The only thing I can report from my butt dyno, is at high speeds it pulls harder. My exhaust sounds a bit louder and I "think" its faster. But then anything must help if it opens up more air. I hope the DIY helps. Its not a hard mod. If anyone needs help, I will do the install for anyone for $15 which includes supplies.
But mostly notice before I installed the grille back on, I closed the hood and could feel sucking pressure from the hose. All that matters for me, haha even if it doesnt work.
UPDATE:
Pictures with the funnel. The funnel helps so much. Its a pretty easy and great mod.
When to a local auto store, bought the liter funnel. Pulled the vacuum hose out. Threaded the funnel on the hose and installed the hose back into the car.
