There is a lot to consider when talking about DIY cai's and it depends on what your ultimate goal is. I think we can all agree that the hemihat is restrictive, and that sucking up engine bay air is not exactly ideal. How you choose to remedy those situations is up to the individual. After reading a ton of posts I was going to do what hammer has done for a lot of them and build one out of pvc and modify the stock box to fit a cone filter in. I figured this would be the best situation as it got rid of hemihat and still used the stock airbox to get as cold as possible of air. I happened to run across an idea to a little different diy cai and went with this instead.

my cai:


I think it is better in that it has a nice long smooth bend instead of multiple direct 90's. It is open to the engine bay, but I may construct my own heat shield at some point if I think the rest of my system (engine, exhaust) is good enough that the extra cold air will actually help. For now the extra flow seems to help. I also read a few posts by drewactual where he was pretty convincing that the extra few degrees doesn't help as much as you would think, especially for systems close to stock, that helped me make my final decision to go with what i have. However you choose to do it, it's a fun mod that is easy to do yourself with some nice results.

 

Lol you should sell your idea to a company, or on here lol people would be amazed you can make a CAI for under 12 dollars not including a filter

 

I bought my pieces at Home Depot. I had them in the cart when I went looking for the Sched40 3" 90 but they didn't have any. Oh well, 6-of-one, half-dozen the other lol

 

Haha, yeah no kidding. Im trying not to plaster it all over the place but i think it is a good improvement over what some people have done. This seemed like an appropriate place, maybe some others looking for diy cai ideas will run across it.

 

What? Dude, the gas never touches the cats. It's all carbon exhaust by the time it hits the cats.

 

he means exhaust gasses...

 

ok well i have a k&n 6.5in filter with a heat sheild on mine that was oruginally for a mustang i have the tube but not the right bends so my cai is on the original intake tube from my hemi with the hemi hat still its a pretty crude cai but none the less haha. i remember reading a guys where he made a cai intake with electrical conduet i think a 45 degree bend on 3in pipe? thats what i want to make for a tube but cant seem to find the diy can someine please send me the link?

Im reffering to the "Carbon Exhaust Gas", its in a gas state therefor making it a gas.
The ions platted in the Cat takes the bad out.

 

Is this what you're looking for?
