CPI Cold Air Intake HOW-TO

Well, there are a few CPI CAI how-to's out there, figured I'd throw my hat in to the ring..

NOTE: I'm still not done with the heat shield but I will explain how it's done.

Parts Needed:

24" of 3" id exaust pipe ($15.00)
3" id Coupler
K&N RF-1016 Cone filter (10 degree flange @ 3-1/2" ID ($40.00)
Bracket
Oil Breather Filter (APC, EDLEBROCK,SPECTRE, etc...)
Orginal mating boot with the IAT Sensor
Optional Primer, Paint, Enamel Clear, etc..



The pipe you see was bought and bent at meinikie for $15.00 It's bent @ 35 degree angles
I primed, painted, and clear coated the pipe just to make it nice...

Heatshield:
For the heat shield, I simply took a heavy piece of card-board and cut it to shape. After getting the edges straight, I covered in about a 1/4" worth of rubber undercoating spray.

Primered:




First pull all of your existing air intake plastic off of the truck. Disconnect the IAT Sensor.
Remove front boot with the IAT sensor and set aside. Store or throw out rest of your system.

Pull the hose running from your driver's side pcv hole and push the oil breather filter into it

The reason for the coupler is that the pipe is 3" and the filter is 3-1/2 so I needed something to fill some of the space. The coupler did this well. Simply slide the couple onto the filter side of the pipe, slide the filter over this and tighten the included clamp. Connect the boot to the other end.

You will notice in the following pics that I notched the top of the fan shroud because it sits nicer that way. Also you will notice from the above parts pics that there is a stud mounted on the end of the filter... This makes a good bracket mounting point. You can't see the bracket I made, but it holds in place nicely,

Here is the final install.

Re: CPI Cold Air Intake HOW-TO

Looks great, do you have any sort of brace to stop it from hitting the alternator pulley?

The bracket on the end of the filter holds it in place...

It's just a piece of flat metal (4" x 1") connected to the rad support...It connects to the threaded stud on the filter

Bah, I wouldn't waste my money on flat panels yet... At 60hz refresh rate they suck, the picture just can't compare to glass yet... When the next generation comes around at 72hz or better, then maybe ill buy some...I'd rather take up the space with my 2 20's

Both 19" LCD's I have do 75hz at 1280x1024.

Re: CPI Cold Air Intake HOW-TO

You may have your windows set for it, but they certainly aren't actually doing 75hz... Look at the specs for your monitors...

Re: CPI Cold Air Intake HOW-TO

I professionally test monitors for a living and I can assure you they are doing over 60Hz.

This is my business:

Re: CPI Cold Air Intake HOW-TO

Obviously you must not be that good at your business or you would have corrected me on one item... Let me clarify response time that is a specification that applies mainly to LCD monitors, although it is often confused with refresh rate. Response time is the measurement of how many frames can be displayed per second. In the case of LCDs, it refers to how quickly a liquid crystal can twist, then untwist to either pass or block the light of each pixel. Response time is instrumental in determining whether or not LCDs can clearly show full-motion video without smearing or ghosting. Since there can be a relationship between viewing angle and response time, both should be considered together. It's more imperitive as use of full-motion video grows (With vid games and such) Historically, where response time has been a drawback for LCDs, CRTs have always been seamless with streaming of full-motion video without error. For this reason, many gamers and users of video playback and editing apps continue to prefer CRT monitors. However, with the combination of the raw material speed and the innovative driving schemes, it is now possible for active-matrix LCD panels to achieve a switching speed of one frame for all inter-gray levels.

Three motion artifacts result from slow response: decrease of dynamic contrast ratio, or choppy motion, and a blurred moving edge. The first two artifacts disappear completely when the response time is less than one frame, while moving edges become clearer as the response time decreases. With today's LCDs, a total response time of close to 30 ms can be achieved, virtually eliminating most ghosting and image trailing from video applications. Sometimes this specification is shown in halves to show the twist, then the untwist time. The full range should be considered, however.... to fully determine the display's ability to accurately show full-motion video. Unfortunatly even with the current response times, LCD's still CANNOT keep up with the speed or clarity of CRT monitors in a perfect fasion. Therefor, until they can achieve the same response and clarity of CRT's they aren't worth the goddamn money!
I should have specified a response time being more important than refresh, but typically refresh still doesn't run over 60hz...And that really doesn't matter as much as it once did with them. But they still suck.

CRT's rule, though flat panels are getting better. i have room, crt for me

that intake looks good. can you hear it ?

Re: CPI Cold Air Intake HOW-TO

Dang. Everything you wanted to know and more about monitors!

The human eye can't really tell a difference over 72hz but those'll be nice when they come out. Mine cost me next to nothing so i couldn't pass them up. with as many machines as I have crammed in this room... its kinda necessary for the space. We're talking practically free here... its nice to have people owe you favors.

I run mine on DVI and they work for what I need 'em for. I have a Dell P1110 (Trinitron) that runs 1600x1200 @ 85hz. For a 21" monitor, a .24 pitch and the earlier resolution is pretty darn good. Thats for games and whatever else I want, but the dual 19" LCDs are strictly for work-related..

Nice insult there. Why would I correct you on pixel response when you weren't talking about that. You said refresh rate.

Re: CPI Cold Air Intake HOW-TO

might be a dumb question, but what ever happened to the IAT sensor? Where does it go on the new setup?
and btw, it was nater's fault for the monitor feud...

Re: CPI Cold Air Intake HOW-TO

How about some picture on how you installe dthe filter brace rlith.

This is a very important bit of information to stop people from having the intake rub their alternator pulley.

Re: CPI Cold Air Intake HOW-TO

All you do is take a piece of metal, drill a hole at each end. Attach one end to the filter stud, attach the other to the core support.. That's it

Did you ever finish that heat shield? If you have finished it could you post some pics of it? Also how did you get the right bends in your intake pipe? Did meinikie custom bend it to fit?

Re: CPI Cold Air Intake HOW-TO

I think whitedime wants to know about the filtered air intake for the pcv system, which normally hooks into the stock airbox(at least on my 94 4.3 cpi) IM assuming a push in breather?

...even though it looks nice... you can buy one already made specifically for your truck, with all mounting hardware... for about $65 shipped from ebay brand new. fyi

Re: CPI Cold Air Intake HOW-TO

did you spray anything on the inside of it? my question would be if moisture gets in there (since it obviously will since its an intake) may it rust a little and sooner or later you'll have shards of rust coming in your motor through your intake? just posting concerns, it looks good tho
