i heard many people say that when manking a cold air intake for a vl turbo, don't use a pod filter cause it's illegal and to simply replace the filter with a better one, make all the piping etc and keep the standard box cause it ain't that bad anyway. So I was going to cut a hole underneath the air box and make a cold air intake that way blah blah blah I am pretty sure this is illegal to cut the metal out but i don't think it will be very visible anyway (compared to the pod filter option). Are there any problems with high amounts of dust/dirt, insects, rocks/pebbles or are these small problems? just curious and paranoid

Just a query, is it possible to install a pod into the air box, and then have a normal CAI system running into it? Or would this be wrong? -Weq

Hey, i have that setup, atm i just have a 45 degree 100mm PVC pipe coming out from under the guard, i find this good just on its own without extending it to the bumper. You get the couple bugs and some dust etc. so you are better off getting a nice washable filter (not sure how much they are, the ones u recoat with the oil stuff). Ummm there is nothing stopping you from putting a pod inside the air box (well u will prolly have to make up another air box because POD most likely wont fit in standard) because having the POD enclosed makes it legal.....

excellent... something for me to do a after uni exams how often would you have to clean the air filter with everyday normal driving (not bush bashing)? thanks

Are there any problems associated with water intake when you connect the CAI tubing up with your front bumber ? I can guess that during winter alot of spray would have to get sucked up this pipe. Do people just disconnect the tubing or does a good water resistant filter ie K&N do a good enough job to stopping water from entering the intake. I am thinking about doing the CAI but I don't want my engine to die if I run through a puddle in winter.

keep the original airbox, it flows perfectly well, if you make a cold air duct keep it as high off ground as possible to reduce chances of gulping water

i disagree with cold air intakes. As stated above the standard unit flows well. A simple modifaction you can do to the standard air box is this...If you take of the front plastic "horn" as some people call it on the front of the air box. You will then see a square hole.. you can then extend the hole right along from one side of the bottom part of the air box to the other with a jigsaw or small saw. A far bit of dirt and dust can accumlate on a pod filter located infront of the bumber which will cause the filter not to suck as well as if it was clean. They do build up alot of dust quickly and you do have to clean them regularly. Its a bit of a pain and worry with water espcially when you are washing your car. No real point hacking into your body to fit one. I understand people like the sound of the loud air sucking noise. Also the oil based filters are worse for dust. There was a test conducted on the dyno with all different types of filters, pods, and cold air intake setups. Conclusion is that the standard filter works best. thats just my 2cents take care Some original photos have not been recovered yet.

I have done this to a few vls and on the turbo motors you do get a good sound when you back off the throttle. Its better than the stock setup and saves the holes in your body. turboluke: That setup would be good when draging on the track with your headlight out. PSI-CHO: I have pictures of the setup.. If someone can post them up for me i can send them to your email address. Sorry i dont know how to post pictures up. It a pretty basic setup take care

whats better, a ramming pod under the bonnet, or a 3 inch cold air induction pipe running out of the bottom of the current air box down to the grill on front of the car? also,would u need to put some sort of mesh onthe front of the pipe to stop **** from getting into the airbox etc cheers lozza

definatly the panel filter in the standard box, with cold induction. A pod wont breath any better than a pannel filter, and will be sucking hot air, as apposed to cold air for the other setup. Also, water spray in the cold air induction wont hurt an engine, it will only be if it engulfs heaps of water, like if the pipe goes under water. some water wont hurt your engine at all, think of all the forcefed cars that have water induction to keep intake temperatures down and reduce detonation.

so you would recommend not putting mesh over the front of the pipe then? cheers lozza
