Air scoop

[Randal Scott]

I asked in a thread Cold Air Intake if anyone seen the Stillen replacement Air scoop. Well after looking at their replacement scoop. I just modified my OEM scoop. Didn't think I wanted to spend over $250. 

So I modified mine kind of to be like theirs. In the area that goes to the filter box, there's a little wall. I removed it. Then I took the scoop out of the truck. 9 pop pins and 2 T15 torx screws. And seen that they only had half the front opened up. So I cut the flap off and open the other side. Then reinstalled it. Here's some pictures.

Don't know how much this will help. But anytime you can get more air flow. It's got to be better! 

Now on to my next project. A cold air intake upgrade. I'm going to use the OEM filter box and just put a tube in.

When I pulling heavy I opened the exhaust and intake. My pulling days ended in the 2000s about the time HP and TQ made great gains. My trucks lived way up in the RPMs, especially diesels. Right at max RPMs. So I opened everything and it definitely helped. Now with 4-500 HP and 800-1000 ftlbs TQ. And lower RPMs probably not necessary. Even my stuff highly modified. Those numbers were hard to reach. Human nature being what it is more is better. Just not necessary.

I did this on a gasoline engine truck. I think it helped with gas mileage and pulling camper.

Any negative side effects of opening up that OEM scoop? Seems like a great idea
