Cold air intake... off road

So I ordered a catalog from www.lmctruck.com, and was looking through the intakes, they have a few to select from but one was labeled to be illegal for streets and off road only, just wondering if anybody knows why it might be that way? It looked similar to the rest of them, although it didn't look to have the MAF sensor in it. But I don't think taking that out and putting a simulator would be useful would it?

It still may be in there I just failed to see one, I was thinking of ordering this one(for when I go off road ) to see if it makes any improvement. It just made no sense as to why it could be illegal.

That means that it wasn't approve and or tested by CARB (California governmental agency that promotes and protects public health)

Most aftermarket intakes come with carb e.o. numbers. I'm pretty sure depending on what brand has that info stemped right on it.

Your engine may run too lean or rich with that intake and it may throw codes to your computer

usually you just unplug the battery if the check engine light comes on from intakes, that's an easy fix I was just curious why its off road only. thanks

I was acctually looking at my intake one day and other then the 2" hole going into the frame, there's not much else to deflect the air flow inside it (02 f-150 5.4) there's a small hole in the elbow but that's a simple plug it with something to stop air from gettin trapped in there, otherwise I'm thinking I might just grab a K&N filter and cut open my airbox like everyone else does, much cheaper then spending the 150+ dollars

very few of them meet CARB.........no biggie.
Airaid is prolly the best followed by K&N........atleast the most power can be achieved through custom tuning with one of these 2 (usually airaid).

yah i'm still in debate about it, i don't believe i would feel much difference with buying one, but on the other hand i do like the looks of the chrome under the hood and it looks less tacky then cutting my air box apart

Volant makes a true CAI by utilizing the fender opening. The Airaid is a nice unit (had one) but it ends up sucking the hot air generated by the engine even with a heat shield.

Airaid is still considered by many of the major tuners to be the one that can produce the most additional horsepower.
And technically speaking the Airaid and K&N are not considered CAI's. They are FIPK's........Filtered Intake Performance Kits.

I can't see an intake making any difference even with custom tuning unless you are running a blower. My tuner guy is one of the best in my area...knows Mike Troyer quite well and he told me there is little or no gains running aftermarket intakes even with my Volant and Airaid kits. Our intakes are meant to produce goobs amount of air at low rpms but that is the problem as well since they don't breath well from mid range on. I can see a Mustang intake can work much better with an CAI but not our trucks.

Sorry but I'm running a ton of bolt on mods and to be honest only headers and an Xcal-3custom tunes yield positive results.
