Intake for my 84 W150

bruin27 · Mar 4, 2015

I'm a newbie with this truck, always liked the looks so I picked one up. It looks like its already set up for some kind of cold air intake as there's supposed to be a duct from the intake housing to a vent in the front. Can I just remove the entire stock housing and replace with an aftermarket one like the picture I attached?

Theres a bunch of stuff like the "electronic fuel system control" box, duct going to the headers, just curious if I can remove all this.

I tried doing a search but didnt see anything similar but if anyone has done this before can you please give me some details. Thanks!

You have the lean burn system and that control box needs to stay since it controls your spark. I don't have any experience with it but if you search "lean burn" there are some threads that can tell you how to convert it to a better more updated ignition control system. If you have any more questions post them up and I'm sure someone will be along to help you out. Welcome to RF.

Could I attach one of these to the stock air filter opening or is it best to leave it open or connect a duct to the vent at the front of the truck?

I'm really not sure how much there is to gain from putting a CAI on a 318. I would at least put on a duct since the way it is now it would be sucking warmer air into the intake.

a CAI would do absolutely nothing on any vehicle out there. all they are is overpriced air filter that change the air intake sound.

as John said you have the lean burn ignition system. i think in order to really start modding you really want to change the ignitiontion system whether you got with an aftermarket setup like msd or a stock 4pin ignition system setup. both options would usually require about the same work but something like msd is about $500 and the stock setup is about $150-$200 depending on where you buy everything.

Well I'm not really going for huge hp gains, I'm really just trying to clean it up with new parts, figured a cai would look good in my engine bay, planning on just simple dress up parts mostly, going for new valve covers also since I need to replace the gaskets anyways.. I want the interior to look as good as my exterior haha.

if you want a clean look you are best to just get a open elements air cleaner and possibly de-smog the engine if you can would make it look pretty good. if you plan on doing any mudding tho you might want an air cleaner like the stock one since it would keep most of the water out where the open elements ones don't

Not doing any mudding, i like that look but I'd rather keep it as close to smog ready as possible as im in California and dont want it to be a pain come smog time.. Just want it as is but as clean as I can make it without shelling out a ton of $$$.

that might explain why your truck is so clean looking. it is from California. since you live in California i have no clue what you are allowed doing as far as the ignition or emissions go. i am not sure if you are allowed to change the ignition system type. i just know i have read some people have a real hard time with emissions over there sometimes

bruin27 · Mar 6, 2015

yea our smog laws have to be the strictest in the country.. all i know is I bought it a month ago and it passed smog so i wont have to worry about it for 2 years... plus if im going to spend any real money on it i need to take care of what seems like leaks everywhere.. valve covers, oil pan, pretty much anywhere underneath the motor that could leak looks wet.. im getting maybe a few drops a day on my driveway so it doesnt seem that bad but from looking underneath it today it looked scary..

Heres some other pics...

usually the main leaks are valve covers, rear main seal and power steering box input shaft. as far as the valve covers go i would recommend just painting the old ones especially with where you live. the aftermarket valve covers might draw a bit more attention to the engine than you would like when you have to do emission testing.

Personally, I would just move out of California and then be able to do whatever I want to it...

If I was there though, I would probably just leave it alone smog wise if it's passing. The hood will be closed 99% of the time anyways. I don't like to fix what isn't broken.
