opening up CAI help
My first thought was to replace the stock system but upon further investigation its already a cold air system. My question is this, the truck has one tube that draws air into the box with the filter than 2 that takes it to the TB, would adding a second tube to draw air into the box add to volume of air being taken to the motor? Im thinking that runnin a second tube to the other side of the engine bay so it draws cold air in from both sides and than to the filter will be beneficial but thats my opinion. Now i would like yours. thanks.
BTW, this is on an 86 f150 302fi.
Or my other thought was running 2 tubes from the TB down thru the engine bay on either side with filters on each below the truck to catch the air.

As a test you can completely remove all the intake ducting and drive the truck around, what you'll notice is it doesn't make any difference. This is because the intake isn't restricting the amount of air the motor is getting, the exhaust is if it's stock, and once you upgrade that then the cam is next in line, and after that then the heads themselves become the bottleneck.

In the spring of the year the cam is gettin replaced along with the lifters an maybe a few other things. And right after that the exhaust is getting redone.
I thought i read somewhere that the heads on these were sufficient enough for this mild upgrade. What would i be looking at to replace the stock heads?
