Smittybuilt USED TO BE good quality stuff, roll protection, tops, seats - lots of goodies. Old man Smitty was always very helpful and honest! But about 10-12 years ago old man Smitty died. The company stopped selling anything for awhile.
Then somebody bought up the inventory and name for a song, they sold all the good stuff, since then most of it is junk from China.
The name should be changed from Smitty built - it's an insult to the old man - it really should be renamed to Shittybuilt.

I use a Sandon - just like the one used on a TJ for air conditioning. Stop into most any repair shop - they'll give you one that they took off because it had a small leak. A small leak won't stop you from using it for on board air. FREE!
It's small and round, fits nicely. Not big and cumbersome like a York.
The most expensive part is a pressure switch - Kilby has them for about $10. You also need a check valve - Grainger.
Fab a bracket, get a longer belt - no tank needed - it puts out 8-10 CFM at 100 lbs.
It'll fill a 35x12.5 in about 1.5 minutes.
It will run an air tool without a tank, but I've never found it's needed on a trail. Better to use that room for a welder.
Pics available if you need them.

They looks pretty much the same to me. For the price of a viair 400c you can buy 4.6 MV50s. Is it 4.6x better?
here are links from that thread.

My 04 Wrangler came with a AEM Brute Force intake . I bought a used air box from Davesjeep.com for $15 bucks and it had a new filter in it . It looks like it should be under the hood . And yes I sold the junk AEM to a guy that had to have it for $70 bucks

Smittybilt MV50 vs. Viair 400p are they the same compressor? -

|Jerry Bransford||Smittybilt's MV50 only looks like the Viair 400c from the outside. It's a good copy, externally. Tear them down as has been done on a few websites with photos of their insides, valves, etc. and you'll see that the MV50 is way different inside and not nearly as well made as the more expensive Viair compressor is. Don't confuse a Smittybilt MV50 with a Viair 400c.|

The york does 4cfm at 90 psi with a high idle of 1200 rpms.
The dual mv50 setup does 2.82 cfm at 90psi. So at a regular idle, they would be nearly identical.

Wow I'm glad I read this thread an CAI was going to be the next purchase I do have a question those of you who have fabricated your own CAI in to the cowl have you noticed any performance gains ? Or had any issues with doing so ? If there are benefits ie hp/ftlb/mpg I'm gonna strart scavenging

Even small compressors can put out lots of air when they aren't having to pump air into an expanding tire that is pushing back with increasing amounts of resistance (air pressure). Once any pressure at all builds up in the tire, the MV50 CFM CFM rate drops off dramatically. It is certainly not even close to being able to run air tools other than for more than about three seconds until the air stored in an aux air tank is exhausted after that brief output.

|Jerry Bransford||I will say that my York based OBA system complete with Kilby mounting bracket, 2.5 gallon air tank, fittings from Home Depot, etc. cost me around $400 total to get up and running. The $35 I paid for the used York F210 compressor helped a lot since a new York compressor isn't needed to run a simple OBA system.|

when's the last time you needed an air tool on the trail? do you plan on breaking stuff so much that you'll be using air tools frequently? what array of air tools do you plan to carry with you all the time?
btw, you can hook air lockers to just about any pump...electric or mechanically driven...as long as it provides the pressure required
|03-01-2011 10:51 AM|
its not JUST an air pump... its a belt driven ON BOARD air pump... everything is mounted and ill i have to do is stretch the hose out to air up my tires AND to use air tools on the trail... not to mention attaching my lockers to it....
try doing all that with your lil thing haha

Which requires an "aftermarket" air intake
|02-28-2011 08:15 PM|
Yup, unless it pulls from the cowl, or a snorkel, its just another hot air intake. Mine makes more noise for sure, but I like it I only notice it after a cold startup, or during heavy throttle. You can hear how it sounds in this video. Scroll to 1:23 and 3:15.
|02-28-2011 07:27 PM|
Hey, I know on my maxima it actually was a cold air intake because it bent down into the wheel well and picked up cold air but are these "cold" air? because it's still pretty much pulling the warm air from the engine compartment

|jgorm||I have the spectre intake.|

|Jerry Bransford||There's not an aftermarket air intake made that I would bother installing even if it were given to me free. The factory air intake was specifically designed to be non-restrictive and they succeeeded in doing so. There are any number of items I could install onto my TJ that would benefit it in some manner, an aftermarket air intake is not one of them.|

Windstar airbox inside the engine compartment.

Mustang GT airbox to the cowl:
Snorkel nose you can use in either direction (from windstar fenderwell):

|jgorm||The air intake tubing cannot cause a high idle. A high idle is caused by a vacuum leak on the other side of the throttle plate. I did some testing on my dyno (search 18 dyno pulls and jgorm) and got pretty much 0 hp with my CAI. I will say that the engine sounds 100x cooler and tougher, and my IATs are WAY lower when going slow, off roading, and stopped. Is it worth $200? For me it is, for 2 reasons. 1. It moves the stock intake out of my way so that I can do the DIY front fender lift. 2. It sucks fresh cold air from the cowl instead of super hot radiator backwash. Maybe there is a "ram air" effect on the freeway. If feels faster, but maybe I'm biased because it sounds so much more bad ass. I'll do the classic "leaf blower dyno" to find out for sure if its in my head or not.|

|Arch Stanton||I spent close to $300 for Mopar CAI and throttle-body spacer. I didn't notice much difference as well. I bought mine based on the positive reviews by JP Magazine reviews of the AEM Brute Force CAI. The Mopar CAI appears to be identical to the AEM with the exception of the oiled filter. In hindsight, I would have saved the money for gas, but I just bought the Jeep when gas went up almost three years ago. I'm sure they will sell CAI and other forms of snake oil now that gas is going up again due to what's happening in the Middle East.|

I don't think you'll get killed for that one. While "cold air" or "free flowing" intakes do offer some benefit to more performance oriented engines, they're useless on a stock Jeep. It's been my experience that anything over 3000 rpms on a Jeep inline is just wasted gas, as most of the SOTP power & torque are in the 3k & under range. On smaller, lower rpm engines you're simply not moving enough air to see any benefit over the stock air box. My most recent TJ had an Airaid on it when I bought it. I traded it on Craigslist for a stock air box and saw ZERO loss in performance, even at WOT.
Secondly, having an open cone filter on something you're going to take off road, especially if you're going into mud & water, is just asking for trouble.

|Pony Hauler||I bought my 04 Rubi with an AEM CAI on it. Where can I buy the stock intake at, without breaking the bank?|
