If that's want you want to call it? I decided to try and make the OEM airbox flow more air without having the ram-air set up. I used a Dremel tool to enlarge both openings by removing all the excess plastic, both openings were smaller than the foam insulator that's around them and the upper one had real rough edges. I ground down the plastic so it's smooth and the same size as the foam. After I enlarged both airbox openings, I reinstalled the airbox bottom and saw that now the openings in the fender were to small, I mark them with a black marker and removed the airbox bottom. I used a grinding bit on my electric drill to grind the metal off and then filed the edges smooth. I painted the edges on the fender openings to prevent them from rusting and let it dry. Reinstalled everything and drove the truck, it feels good but that could just be me wanting it to work. I would say the I increased the top opening by a total of 8-10% and the bottom opening by 30-40%. This is the fender openings, which I believe were already smaller than the openings on the airbox, when I enlarged the airbox openings, it made it more noticable. I gauge that by the amount I enlarge the fender openings which are now the same size as the airbox openings. Just thought I would pass this on.

take any pics?

is there a SOTP difference?

 

Yeah.. pics would be nice.

 

OK, I'll try and take a pic when I get home, at work now goofing off (Shhhhhhh!) I'm not sure if it'll really show much though. The lower hole on the fender did get opened up quite a bit while the upper opening was a little.

how many intakes have you gone through now?

 

why not just cut a huge hole in the front of the box?

 

Well, since this is the stock one, I haven't gone through it, just played with it. In the 3 1/2 years I've had my truck, I've had four (OEM w/ ram-air, K&N, UPD & Pro Cold). I haven't lost much, sold one to buy another.

I already have a ram-air set up with another OEM bottom, just wanted to see how this would work.

Yep, driving home from work tonight, the truck felt really good. I did two 0-40/0-60 stop watch runs and the times were as quick as they've ever been. The times were 0-40 in 2.94 & 0-60 in 5.94 in the first run and 2.91 & 5.91 in the second. Like I've always said, I don't claim my truck is actually that quick, I do the runs to see if there is a time difference with a mod. It looks like porting the two air inlets on the air box and in the fender may work afterall. My stock 0-60 time with the same watch was 7.35, I didn't do 0-40 times back then.

i think that is pretty goood for an EC
