Custom cold air intake and cone?

[Tremblor]

Anyone have any good suggestions for creating an aluminum cold air intake, to a cone filter? And is there anywhere i can route my cone filter so it picks up extra air from the grill? And lastly, is it worth it?

If your going to do a cold air intake you might as well do an exhaust too. They will benifit each other and you will see more power gains (Not alot but should be noticable). if you do a CAI make sure you keep your MAF. I plan on doing a snorkle on mine later on down the road and i will start the piping after the MAF ( leaving the engine) and run it from there. if you are only running it to the grill it shouldnt be to hard.

You can just get a MAF adapter for the stock assembly, and put a cone filter onto that.

I'd suggest using a K&N or S&B brand filter for the best air flow and filtration, the generic brands (Pilot, Spectre, APC, etc.) don't have the same million mile warranty or performance.

KKM sells a bolt-on cone intake kit for the 91-94's, I've had mile a looooong time and it's top quality. It's slightly more expensive than buying a universal MAF adapter and a K&N, but the Explorer-specific fit is worth it to me.

If you want the custom tubing instead of the stock stuff, you'll need to go to an auto parts store and grab some of the custom intercooler/intake tubing and connectors and make your own. The stock plastic might be better, since it's not metal, and won't retain the heat as much as the aluminum or steel tube, keeping the incoming air cooler. If your stock intake is cracked and leaking, it makes sense to replace it, though it is possible to repair it some with silicone.

Routing depends on the Explorer model year and engine compartment layout. If you have the battery on the very front passenger side, there's not much you can do without relocating it. If the battery is in the middle of the passenger side or on the drivers side, you can locate the air filter behind the headlight, and use some plastic to make a deflector to keep the engine heat away from the filter. Later Explorers also use this setup so it's possible to modify a stock intake or get an aftermarket one and adapt it to your Explorer.

Did you notice any increase in power or fuel economy with the cone filter? Or will that only come with aftermarket headers and exhaust?

i have a cone filter on my truck.... that ***** moves now

no answer for fuel economy. i have a heavy foot

I got some pretty big gains with the intake, but you REALLY need an exhaust to go with it to see the whole benefit. Just a good flowing muffler and/or cat-back system is fine.
I'd suggest the Dynomax Super Turbo kit, especially for a '92, it's 2.25" pipe all the way back, and the mandrel bent pipe behind the muffler makes a big difference too.

You don't need headers on the 4.0 V6. They are a waste unless you do internal mods like a camshaft to change the whole tune and powerband of the engine to the higher RPMs.

Of course, it also depends on the shape of the engine and everything else. An engine in good tune, with good plugs and wires, a clean intake, throttle body, MAF, that's well maintained will see bigger imrprovements than just slapping performance stuff on a motor that's poorly maintained.

Fuel economy goes up slightly if you can take it easy, but don't count on it. With the increase in power and torque, it's a lot more fun to drive, and you will be enjoying making it go for quite awhile after the mods.

My engine has just over 200,000 kilometers on it and I'm doing maintenance on it almost every day. I keep my intake all clean, and change the air filter, oil filter as often as I can. The motor runs flawless, and has no tick or knock at any temperature. If I could solve this fuel in my oil problem, I wouldn't have to change my oil every week. So I definitely think the engine qualifies for some intake and exhaust upgrades. as soon as it warms up here im going to start doing the intake and exhaust, aswell as doing the spring over axle flip and F150 spacers and some longer coils in the front. thanks for your input.

Solve your fuel in the oil problem first. The sooner you stop having to throw money away changing the oil that often the sooner you can have more dough for the mods.

Oil in the gas might just be a blown head gasket, or might be a cracked head, if so spring for new heads. I'd suggest w/new valvetrain and get new ford rocker arm kits w/pushrods for both sides, after 200,000+ kms the rockers and pushrods wear out. Even if you're not getting the notorious valve clatter yet, the revised rockers would just make sense if you go to the trouble of slapping on all new heads.

How can i check to see if the head is cracked or the head gasket is gone? I don't get any oil in my coolant, nor do I get coolant in my oil. I also have no air leaks. the truck idles at 600 rpm steady.
