Hey everyone, I was looking on ebay and I found a Bomz racing cold air intake. Are Bomz products any good? I looked at their site and it said it was the leading aftermarket manufacturer(sp). Anyways I wanted to know what you all thought about them before I bought one.

Thanks

 

From their pictures it appears that filter will be located under the hood in the engine compartment. That looks like just a nice looking intake tube and air filter. A functional cold air intake will take air from either fender or bumper. If you see a filter under your hood, then it's just for looks. A filter shield will help some but only if filter breathes fresh outside air.

Also, when buying one you need to watch out where MAF is mounted. If it's mounted right behind the filter it could skew the MAF reading at low speed, due to increased air velosity through the MAF, resulting in lean condition, check engine lights, and poor gas mileage. MAF should be located further up from the conical air filter.

 

I have a BOMZ CAI and I'm very happy with it. It's cheap, but does the job and I've yet to blow a code or have ANY problems. The air filter mounts in the fender, and everything else is in place as it was stock. Nothing is really out of place and you can hear the "whoosh" of air coming in on startup and when you get on the engine.

I am very happy with mine.

 

If filter is inside fender then yes, that's a cold air intake. Snap some pictures.

 

Even if it's in the engine compartment its still a CAI.

 

Only if it's enclosed in an air tight box that takes air from either fender or bumper. If filter is exposed to the air from under the hood then it is a "HAI", hot air intake.


This would be a true cold air intake.




while this is a hot air intake. That filter is sure a sight to be hold when you open that hood, but it sucks hot air from under the hood, and all the benefits of installing a CAI are gone.

 

If you say so, I've argued this 1000 times and I don't feel like doing it again.

 

Im new and curious. Care to repeat once more?

 

Eh, sure.

There is no such thing as a real CAI, unless you have some sort of an air conditioning vent in front of the filter or take you passanger headlight out. The problem with a CAI that mounts in the engine bay is that they take in warm air from the engine because it produces so much heat. And the problem with a fener mount CAI is that it still takes in warm air (even though it's cooler then the engine mount) but does not take in as much air, due to the fact it's restricted inside the fender with no way to get constant fresh air. Thats why when you go to the track, the guys with the fender mount CAI's usually take out their passanger side headlight (to allow for cool fresh air). But as soon as they put it back on the air flow is restriced again. So yes you will be taking cooler air with a fender mount but you will not be taking in as much, so which is better? I personally have a one that mounts in the engine bay and I never had a problem, the heat shield helps a little. But most guys like fender mount. But the reason I argue that the fender mount is not a real CAI is because it's still taking in warm air, even outside the engine bay. Whatever you like you get. Seriously there's not much difference. In my eyes there is no real CAI unless you have a way of getting fresh air into the filter like when you take the headlight out, but thats illegal for the street.

 

Ahh. So both setups have their negatives...

But is the airflow in the fender really that restrictive for it to negate any benefits of the cooler air it takes in?? And doesnt the spinning wheel produce a kind of updraft of air that would shoot straight into the CAI?

Would be cool if you could
1) Record the average temperature difference between the engine bay and the fender.
2) Dyno the car with a similar CAI and both setups
3) See which one produces more HP, and better fuel efficiency.

In terms of price, are the two setups the same?

Are there any websites that did this sort of experiment?
