Well so i was sitting on the net, going over all the CAI designs, ones you can buy and so forth. I remebered that a member of the forum had some templates. SO got those and went to work.

My dad and I started in the morning on boxing day, figured we would take it easy, well 4 hours later, and a six pack of beer, and HAY PRESTO, here is the finished result.

The box case is made out of a product called ALUCOBOND, it's a 1mm ally, with 3mm PVC, and 1 mm ally again. You can buy a thicker ones if required. The inside is lined wiht a THERMOFOAM, it's a 15mm thinck high density foam with silver foil, excellent R values, to miniminse heat transfer. I noticed a 6deg C after introducing the foam.

The air is introduced through a 2'5" pipe from the front of the bar and blows straigh into the box.

SO far the results are great, the car is a lot more constant, if you stand in trafic, the heat lag is gone. The air is nice and cool, and the car is a lot more responsive. Fuel ecconomy is up, and the pod noise is reduced to a more acceptable level.

Only down side, on a cold morning, the dam thing hits R&R so dam quick, as the air is so dense, and the box together with the FMIC, really increase the air flow, hence R&R.

I have the templates available, if people are interested, but i modified mine as i went allong, i found that each car is different. I have done this to my friends R33 4door, with an APEXI filter, and we had to extend the main box body and make a different cover top.

I did mine by making the side first and then making up a pattern to fit for the top cover. The side of the box is held in place by two brackets riveted to the side of the box, and bolted to the car using the stock airbox mounting holes. The top is slid inot place under the front panel, and then bolted through the top, into some brass L-brackets. I then finished the alluminium by brushing it with fine still wool. I did have it polished, but it was VERY hard to keep semi clean. Total cost, ALUCABOND, free i got offcuts, Thermofoam $36 per meter, and all the other bits and peices i already had, so that is DAM Cheep.

Tell us what you think.

looks shmick.

I've been meaning to make one, but just waiting to get my hands on a snorkel before i size it all up.

WogsRus, you should consider selling them on here. I'm sure there'd be alot of interest, especially if your prices arent over-inflated like alot of these boxes are.

Like i said most of the materials for me were of cuts, and there is plenty more to get. The only problem is that each box is really individual, if you want to do it corecctly. I made sure that there was no leaks or anything, the box fitted well. Depending on each car's setup, the pod hole may be in a different spot and so forth.

I am happy to farward on the design templates as were give to me, i can't take credit for those. I simply improved the design a little, and made it more functional.

BUT i suppose if you had to get materials yourself it would range from $50 if you get some scraps and stuff or about $100 if you did it all brand new, but for $100 worth of materials you can get 5 boxes cut.

Here is teh templates and some instructions as i recived them from the original maker. I do not take credit for these.

MY design is slightly different, in that i made brackets up to hold the side part of the box, and some brackets to screw the top down into.

Like i said i made mine as i went along, but the template is a good base to start with.

If you need any more info, PM me and i'll try and help, and provide some more pics.

Hey all i am in the process of making one of these for my s1 4 door. The only thing where something can differ is dependant on what type or airpod you use. I have an apexi and wog has a hks one. the hks filter sits off a pipe that you can go around where as the apexi bolts straight to the aiflow meter, so its a bit more tricky to get attached

I used the old hole form the stock IC, you can see it in one of the pics. There is a 2.5" pvc pipe that runs form there to the front bar, and picks up cold air form the front of the car.

You could easily use a stock snorkel and plum that inot the side of the box at the top, but i didn't have one.

If you are looking at the pics of the white car, the orignal template pics, he made a hole in the front fender to duct in air. I didn't do this as i already had a hole.

BEST thing if you have a stock snorkel, use that to supply the cold air into the box.

EDIT: I can't spell at ALLLLLL

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
