I had the 4 speed for a couple of years....definitely don't miss its highway power haha.

Does anyone make a true cold air intake for a deuce? Something that takes actual cool air in.

I dont know why people this this is some sort of rocket science or that it has to be a "manufactured" product.

Plan out where you want the air to come from.
Its an off-road vehicle so some people will make a snorkel (yeah I heard some say the snorkel looses power, but if you do that are you doing it for power or for protection?), or you can route it to the front of the rig, or to the side of the engine bay where it collects it now.

All you need is some pipe (metal, stainless, PVC, whatever), some hose couplers, some screw type clamps, and a performance filter as big as you can shut into the area you want to put it in.
You get all that together for about 50 bucks (if that... since the biggest expense is the filter and you can get those fairly cheap from Amazon or eBay).
After that, you can take some plexi, or some metal, or again whatever and fab up a nice box to encase the HUGE air filter and done!
A little paint and it is all pretty
You now have a great CAI for a few hundred less then what you would have paid to buy one that isnt exactly what you want.

Why spend 150-350 bucks (or more) on something that - at best - gives 10-20 hp all because it looks pretty. Sorry but I dont drive around with my hood open all the time for people to see.
Fab up something for a few buck and take the extra money and invest it into another mod that you can fab up



Hope this helps

Now this has me thinking...it would be fun to build my own intake.

Ryaleon, gears is your answer, especially if you are pushing 37's. that will give you the instant return to the stock feel once you get that ratio right. I suggest going 4.88's as that is as big as you can go on the front. Adding intake and exhaust and headers in that order will help too, but you need the gears first. Any time you go up in tire size you should be looking to regear so that your power gets rebalanced correctly. You don't do this, this is why you downshift so much. Your engine has almost 100 more horsepower stock so you have plenty of power. We have to do tons of mods just to get near where you are stock.

In short- regear is your answer.

Agreed...'gears'...when I went to 37s the umph dropped. I moved to 4.56s and it ended up a tad snappier that stock. 4.88 will pump it up another notch, but be mindful of your top end...your RPMs will be higher on the top end the lower you go with your gearing. So if you do a lot of highway travel 4.56s might be more 'fuel efficient' for you than 4.88s.

If you're dead set on going the CAI route AND if you don't plan on serious off-roading, you could always replace the stock air box with a K&N and cut a section out of the hood directly above and mount a universal scoop to force outside air in. That would be better IMO than a snorkel...snorkels are worthless unless you plan on submerging your vehicle in water that can reach over the air box, and if you're in water that deep you better have a diesel or you'll have more worries than water in your intake.

These Landys, FJs, Jeeps, and whatnot that run around town with snorkels crack me up...99.5% of the snorkels I've seen were installed merely for show.

Right but the stock intake system draws air in from the fender which is cool air. Most systems just suck in hot air from the engine compartment.

I think the stock system is perfect which is why I went with a Volant box.
