I'm sure that this subject has been discussed many times but i just today attempted the whole home made CAI and i think it actually turned out pretty well. And it is very simple. Here are some pics although not very good ones. Let me know what you think!

thats pretty good how lond did it take you to make arent you worried about suckin water??

 

It took me about an hour and a half and about 50 bucks and the filter is high enough from the ground that there shouldn't be a problem, just can't hit any big *** puddles anymore, but it's worth it.

 

looks great and well worth the time spent vs monvey saved....close to 250 bucks most likely. also like the painted touch

looks nice but how well does plastic hold up as a cai? i would be afraid of something breakng off and getting sucked in. engine moves around some especially the way i drive.

 

im gona have to knod my head at that one two... as long as the plastic doesnt dry out and become brittle and the mounts are flexable i would see no issue.

 

How did you support it? I know my K&N kit has a few anchor points where there are rubber grommet fittings which allows the engine to torque without effecting the intake.

 

I gotta say to anyone attempting to do this to your truck....

STOP

Major automakers put considerable concern toward the design of every aspect of their cars. Companies such as K&N and AEM and all other serious manufacturers put thousands of man hours into developing and perfecting systems to improve performance while maintaining reliability.

Strapping painted PVC on to your throttle body demonsrates a lack of understanding of the complexities of modern internal combustion engines. Those attempting this will likely lose performance while compromising the health of your machine. If your into your truck enough to consider this do your truck a favor a pony up for the real thing.

Proponents of DIY jobs are welcome to submit dyno tests with before and after readings to prove me wrong. Also, I'd be interested in hearing any expert opinions to the contrary of mine (admittedly not expert).

I dont know, i see no harm in it. All the really fast guys over on DTW see no problem in the homemade intakes. I don't hav eone but I see no problem with them.

 

Did I miss something? Isn't it still an air pump?
So can K&N and AEM, but you will be believing their data. I noticed your truck is "chipped." That voids warranty, CAI and exhaust doesn't. Why? Because engineers, and companies,trust their programming, not someone else's. Changing things like timing and a/f ratio without a feed back, how do you know it doesn't go too far? How do you knowyour truckis neverrunning lean? When I modded my 4wheeler, the carb was jetted on a dyno where a/f and timingwere monitored, and I have settings for summer and winter temps.

The parameters on a factory computer are wide enough to compensate for minor changes, like weather, intake, and exhaust changes. There's nothing wrong with creating your own intake for your air pump. Will it increase anything but noise? I don't know, but I don't believe the expensive systems do much more than that either.

If you can give real reasons to notbuild your ownintake I will listen as will others. Oh a quick question: Which flows more? A single 3" exhaust or twin 2.5" exhaust? Can you do the math? I can.
