1990 302 Cold Air Suggestions?
Has anyone fabricated a homemade cold air system for the dual throttle body on the 90 302? I am considering making one and have not been able to find suitable rubber or plastic pipe to use. I plan on using a couple of the universal cone filters from the auto parts store or possibly combining the dual throttle body intake to one cold air cone filter. Any suggestions?
Thanks,

Have you seen the below in the archives ? Maybe this should be a tech article...

K&N part number is RF-1012SUPER easy to do. If you look at Ray's Truck (AKFord351's gallery) you'll see what you need. Basically, you just loosen the clamps on the rubber air tubes and remove the airbox completely. The replacement filter sits where the airbox used to be (I also used a small angle bracket to secure it to the fender) Now you need to attach the filter to the air tubes. I found some 3" exhaust couplings (about $3.50 each at Canadian Tire) that worked well; other people have used two 6" long pieces of 3" PVC pipe. Simply attach the hoses to the pipe, and then the pipe to the filter. All you have to do now is figure out what to do with the crankcase breather filter (that's the hose that goes from the oil fill spout to the old airbox). The K&N filter comes with a 1/2" hole where the hose is supposed to go to (but it doesn't come with any hardware or hose to attach it), so you could buy some hose and a barb fitting of some sort & attach it that way. For a while, I simply plugged the hole in the filter with a brass plug (99 cents at Home Depot) and left the original hose and filter on (it kinda hid under the K&N filter). I now bought one of those cheap round crankcase breather filters (about $10 in the ricer section at your local speed shop) and attached that to the crankcase.
have a way to make one for about $60.
1 = First you need to order the actuall K&N replacement element for the FIPK which is RF-1012. You can order it from any place that sells K&N filters ($45-$50).
2 = Once you get the filter, take it to a local muffler shop and get two pieces of 3" pipe about 4in in length. The openings in the filter are 3 1/8", so the muffler shop will have to expand the pipe for you. Tuffy sold me the pipes and expanded them for $5.
3 = Next get a Brass 3/8" pipe plug to plug the valve cover vent in the air filter. Use some silicone to just to be safe.
4 = Remove the air box from the truck and cut the bottom asectiondown so that there is only about an inch left all that way around. *Leave room for the valve cover vent though. Also dont cut the cold air induction opening out either, this way you can still get cold air the the filter, plus it will help hold the bottom sectionof the bax in place along with the vent.
5 = Put the bottom section of the air box back in, attach the air filter to the two rubber intake tubes and you have yourself a poor mans FIPK.
You can rig up a bracket and attach it to the fender too, if you think the filter needs more suport.
Check my gallery, i will post some pics there shortly so you can see what i did. Hope it works out...

I have a '95 F150 4X4 302, and I had a question about this also. I searched through a bunch of threads about this subject, and one of them sent me to a study that was conducted at a university. turns out that the best cold air system is to use the stock setup and wrap the intake hoses and air box with heat tape, like the kind sold by thermo-tec. since my truck came with the stupid ribbed hoses, i found some smooth hoses through the classifieds and wrapped them with the thermal tape, and the airbox with thermal sheeting. all this is available from the speed zone 24-7 website. The thermo-tec tape comes in 1 1/2" X 15' rolls, and one roll wraps each 3" hose exactly. Each roll costs about $14. The sheets (adhesive backed barrier) come in 12" X 12" sections and cost about $10. Two sheets will be enough to wrap the airbox. You will need to slit the sheets in order to account for the ribs on the airbox. The intake section coming from the hood to the airbox can be wrapped with another roll. So, three 15' rolls and two 1sq.ft. sheets will run about $62 without S&H. Speedzone24-7.com has the best prices on thermo-tec. dont bother shelling out for the ultra tape either because the regular thermo-shield adhesive tape protects up to 2000 degrees!
