Turbocoop Posted December 22, 2007 Report Share Posted December 22, 2007 I wasnt about to pay $200+ for a K&N thats exactly the same as this so I made my own: Parts: 4" 45deg bend w/ 8" legs 90deg 4" coupling 4" to 3.75" adapter (for MAFS) You will also need a cone air filter with a 4" inlet, I used a K&N I had laying around. And you will need some screw type hose clamps, you can use some of the stock ones, I think I had to buy 3 extras total. It was really easy it only took about 30 minutes total to install: WARNING: I am not responsible if you hurt yourself because there is some cutting you must do with a razor blade and it is dangerous if you dont know what youre doing. Always cut with the blade facing away from you and keep your fingers away from it! 1. Remove the IM cover. Take off all the stock intake stuff, including the airbox and the little metal tray that was under it so you get more airflow to the filter from outside. Unplug the MAFS. 2. Cut the 90deg coupling so there is only about 1" left on one side, enough so it will slip onto the TB and you can tighten it down(you probably dont have to do this if you have e-fans, but I did). Save the leftover 4" rubber piece, you will use it later. I used a razor to cut it too but be very careful. 3.Eyeball where the coupling will hit the fan shroud and cut it carefully with a razor knife, I got lucky and got it on the first time. 4.Cut about 3 3/4" length off one end of the metal pipe, that will be the side the MAFS goes on so mark it somehow. 5.The 4" to 3 3/4" adaper slides onto the MAFS on the TB side, I think I had to wrap a few layers of tape around the MAFS so it fit on there snugly. Then that gets attached to the end of the metal pipe with that leftover 4" rubber piece you cut off of the 90deg coupling. 6.Now you can either attach the air filter to the other side of it and put it all in together, or put it in like it is then attach the air filter once the pipe is installed. Either way just snug down the hose clamps and test fit everything, then you can move it around to where you want it and tighten them down. I am going to make some kind of bracket for the filter cause it moves around a little bit. Ill post that up when I do something. If you have any questions PM me Quote Link to comment Share on other sites More sharing options...
Turbocoop Posted December 22, 2007 Author Report Share Posted December 22, 2007 Oh yeah, I think I spent like $100 total on the parts and shipping, including the filter. Good luck! Quote Link to comment Share on other sites More sharing options...

Quik Posted December 22, 2007 Report Share Posted December 22, 2007 advantage of having a true CAI as it seals off heat from the engine bay. get a shroud on there and some rubber stripping and seal that up Quote Link to comment Share on other sites More sharing options...
magna man Posted December 22, 2007 Report Share Posted December 22, 2007 man i bet ur IAT temps are high Quote Link to comment Share on other sites More sharing options...
Black2003SS Posted December 22, 2007 Report Share Posted December 22, 2007 (edited) Nice little writeup. Like said above, get some sheetmetal/aluminum and cut a hole in it for the tube to pass through and seal that area off. Also, what was the reasoning for using mild steel tubing instead of polished aluminum? I think you can find some nice polished aluminum tubing on ebay and other places. I'm just asking, not criticizing. Found some on ebay... http://cgi.ebay.com/ebaymotors/4-0-x-45-AI...ksid=p1638.m118 Edited December 22, 2007 by Black2003SS (see edit history) Quote Link to comment Share on other sites More sharing options...
smoke03 Posted December 23, 2007 Report Share Posted December 23, 2007 impressive write up but like these guys are saying ...get a shroud on that thing and you'll be good to go! Quote Link to comment Share on other sites More sharing options...
Turbocoop Posted December 23, 2007 Author Report Share Posted December 23, 2007 yeah ive been thinking of making a heat shield for it, I just dont have access to a brake anymore so I dont want to try to bend it in a vice cause it will look like ass. Ill think of something though. Im gonna take a trip to home depot today. And I only did it in mild steel cause I was gonna paint it black anyway- I kinda got an all black theme going with my truck Quote Link to comment Share on other sites More sharing options...
Quik Posted December 23, 2007 Report Share Posted December 23, 2007 mild steel will hold in heat, also it will get surface rust on the inside from condensation and etc so that could make it into the motor. atleast its not FI Quote Link to comment Share on other sites More sharing options...
Turbocoop Posted December 24, 2007 Author Report Share Posted December 24, 2007 I painted the inside of it too Quote Link to comment Share on other sites More sharing options...

STKING Posted March 17, 2009 Report Share Posted March 17, 2009 The links are up there in the first post Great write up! I can't seem to buy the intake pipe from that web site. Do you know anywhere else I can pick one up? Also Do you have the part number on the filter? Quote Link to comment Share on other sites More sharing options...
