was Playing around on egay and came across Bomzracing cold air intake

looks alot like the AEM but with less couplers, and half the price. ($150)
wondering if anyone Purchased it, would be nice to know the MAF area's Diameter

 

If I were you I wouldnt mess around with an Ebay CAI. The MAF is too sensitive. Just pony up and get the AEM.

 

Is it me or is the bracket on the wrong side?

 

Is it me or is that lettering photoshopped by like a 12 year old?

 

it is assembled upside down,

I just found it, Just wondering if anyone bought it or knew if the diameter of the MAF was the same as the AEM. it looks like an AEM copy so I would guess it would be the same.

 

you should send the seller a message and ask him to measure the maf section

 

Just did, I also looked on the BOMZ racing website, and they don't have the intake listed on their site, kinda interesting

 

Did you notice the slight bend immediately after the MAF sensor location? That's not how the AEM is built.

 

Two reducer couplings is a bad sign, looks like the front section necks down


.

 

AKA dont buy this POS

 

I wouldn't worry about the reducers, the aem uses 1 plus that large coupler with the bulge to change pipe sizes. My concern and I cant believe I was the first to notice it. Where are the maf screens? No maf screens = BIG PROBLEM. You could take some screen door screen and place it around the pipe end and secure it with the coupler but it's a little far from the maf. Don't touch this intake unless you want a big headache.

 

I have run screenless in both STU and now STX without issue. The whole MAF sensitivity/screen issue is highly over-rated.

My problem with this intake is that the front filter section is smaller diameter than the back MAF/TB section. Is the MAF section oversized or is the filter section undersized? Either way it's a problem IMO.

 

A lot of people have constructed their own CAI without an issue. I personally wouldn't do it, but that's simply because I value my car. There are some places where shortcuts are okay, but your air intake isn't one, IMO. There are too many issues with the pictures alone (bracket location, size of tubing, etc), so I would leave it be and spend the money on a quality product that's been proven.

 

screensssssssss

 

When I first set up my supercharger I tried running it without a screen and the MAF readings were very irratic. I put in a screen and it was much better, it does help smooth out the air flow and improves MAF readings. Can you get away without it? You have and I am sure others have too, but I wouldnt take the risk on a MAF based car, IMHO. Mazda, AEM and racing beat all run 2 screens for a reason.

The OD of the AEM intake pipe on the filter section is 3.25" and the maf section has an OD of 3.5" and it runs two screens. My guess is this intake has a filter section of 3" because I have never seen a 3.25"-3.5" reducer coupler. AEM has that funny looking coupler to do the job.

 

I have a 3.25" x 3.5" reducer coupler if anybody wants to buy it

I'll concede the FI has potential turbulence issues on the intake. I run NA and the only critical point I can see is that the filter inlet needs a smooth radius leading into the tube.

 

This Picture shows otherwise

 

Yes, it shows that there's enough straight space behind the AEM!

 

well the seller said it was only 3" Darn....

 

Its safe to assume the seller doesnt know much about the intake or our cars.

The picture would suggest otherwise and its safe to assume the seller doesnt know much about the intake or our cars. There are 2 reducers of the same size. we know for a fact that the throttle body is 3", so we know that the maf tube cant be 3". It must be 3.5" or 2.5". A logical conclusion is that the maf tube is 3.5" and the second reducers is to connect the 3.5" maf tube to the 3" filter pipe.

However I still dont think this intake is worth buying. No intake screens, (not required but do improve maf readings) and only a 3" filter tube ( Aem/mazdaspeed uses 3.25").

Save your money and find a good price on a used or new AEM, or cheaper yet, drop in filter and modifed stock intake.

 

I wouldn't cheap out on performance parts. Save up if u can't afford the Aem/Ms one.

 

I may modify the stock intake, I wanna hear it

 

midepipe with AP will get you more performance.


got more emails from the seller, turns out its 3.5 at maf but only 3 inches on intake side, and there are no screens at all. too bad....
