Tools: 10mm socket wrench. Hammer and 2x4. Vice Grips Pliers Flat Head Screw Driver Refreshment: Cool Lemonaide / Fosters. Follow the steps numbered in the picture above. You will remove the quarter panel using 10mm socket. Dont forget the bolts underneath the corner lights and around the front spoiler. Remove the airbox and "U" airduct connector from the body frame as seen black tubing in the picture above. Remove the airbox from the MAF held by four bolts 8mm, and one bolt 10mm in by removing the air box cover.

I see this as a draw back, because the MAF absorbs / conducts heat by the engine headers. Thus, throwing off the real outside ambient temperature readings by 1-5%. Later models "I believe" the air temp sensor was relocated in the airbox to counter act, reduce heat exposure affecting the AIT sensor. Installation of this CAI will move 150% CFM more (colder)air over the stock air intake system. The MAF exposed to heat exhaust headers will be null, resulting with better accurate readings. :-X If you see the Air Temp Sensor at the bottom in your Air Box - pop the washers to remove it. You will have to incorporate the Air Temp Sensor in your Air Duct tubing - just as the OS/2 sensor mounted on the header. Once you remove all the stock airbox components. Make the opening hole to the MAF to fit a 3inch-diameter flex according hose. Notice the tool for Hammer and 2 x 4 – will need some muscle to this mod. You can get these parts from Autozone for under $15 USD and 5 bucks for a rubber coupler for K&N Filter, $5 USD for MAF Adapter to connect to flex air hose. Its a very simple mod. Reverse the above steps to reinstall. You may want to bondo / weld plates to fill the air gaps into engine bay. Note: The Flex hose ~ the accordion tubing. Will not impede air going to your MAF. The ribbings of the inner tub will cause rolling air turbulence effect in direction of the air coming. There circular pockets of air stay in the deep channels of the tubing rolling the on rushing of air into the tubing ~ think of it you putting serveral marbles on a level table and you place something flat like your book. What will happen to the book if you push it. The book will roll on the table. The picture above shows the little air marlbes rolling the high stream air through and better yet channeling around the bends. Now compaired to a smooth tubing with bends ~ you get friction around the bends. The air pockets in the accordion affect tubing design comes from JET technology in the afterburner section. Its purpose is to move hi jets streams of thrust. I installed this mod a while back and now just getting to write this up. This CAI method is easy cleaning. To clean your airfilter the front lower left of the wheel opens the inner wheel well by two 10mm bolts. Remove the two bolts out, lower the lower inner wheel well panel lip, and your K&N filter type will slide out - flex out- for easy cleaning -recharging. Your CAI filter being in the wheel well keeps your airfilter clean up to 6months. RESULTS: You want performance - you will add quicker throttle response from outside cool air for low to high end RPM band for Fe, Ge, GTE. Provided that you have a balance N/A setup. If you can improve on this concept ~ it pretty much common in DSMs. *** WARNING DONT DO THIS MOD - IF YOU DONT LIKE WIND FRICTION***
hey guys heres my version of it i didnt need to take off the body panel thing off , no cutting was involved just went through the hole closest to the headlamp, straihgt down and into the pod pretty easy .
see now i would think that having the pod in the wheel well would induce colder air and possibly more. and i am all for that. but it just looks like it might be worse for the car SHOULD you encounter a large puddle, or rain like forrest gump did: Forrest: (voice-over) One day it started raining, and it didn't quit for four months. We been through every kind of rain there is. Little bitty stingin' rain... and big ol' fat rain. Rain that flew in sideways. And sometimes rain even seemed to come straight up from underneath. what about relocating the battery to the trunk, doing a pod style filter with a partial enclosure and the either adding a hood scoop or i saw someoe made hood vents on here with mesh over them. it looked ooretty good. who was that? also you guys that do have this mod, are you losing mpg or gaining it? losing it right, because the ecu has to add more fuel to the air to make the ratio compatible. shoot i think i am going to build a box around my air filter and see what kind of milage i could get! haahahahaha
i dont have this mod anymore , instead i have this but i am going to move the pod back to the afm and build a cold air box around it , mainly because i have room now because the battery is in the boot , i only had the wheel well mod with the pod because while the battery was in the engine bay , it was blocking off most of my air that comes in
it rains quite a bit in western washington...how can i do this mod without getting the filter wet? and without re locating battery
Simple answer, you don't. You'll have to nut out a completely different method that will allow for water exposure without the obvious adverse effects, i'm working on something a little like that with some mates, when i get it sorted i'll let you know how it turns out. Note: my method currently requires a bit of fabrication and metal work so a good idea to make friends with someone who works with metal and is handy with a welder.
