Has anyone tried this "Less restrictive air intake" from Racing Beat?

http://racingbeat.com/FRmazda3.htm

It is supposed to supply more and colder air.

 

I used to have one on my 93 and it did help although not as much as my Apex.
If you want to try one I'll let mine go (with a K&N drop in filter) for a reasonable offer.
I can take some pics and send them to you if you want to see them.

 

It is not a cold air intake kit. It is a air inlect duct. It replaces the crossover flat/rectangualr tube with their small duct. The concept is excellent but the quality is below poop on a stick. The should have made it out of fiberglass or even thick plastic, not paper thin plastic. Again, the concept is excellent but a rip off at $100 because it crubles like a dried leaf, maybe $20 is ok. I've asked for people/companies to duplicate it in fiberglass but not enough interest. You are way better off buying Adam C's cold air kit for your stock box and dropin in a K&N filter.

 

Don't have any issues with mine. Just don't silicon it together. Much better throttle response with a K&N drop-in. Sure a conical intake would be better but works just fine for my purposes.

 

Mazda engineers did a test with the stock intake. They found that it actually sucked warm air back thru the intercooler at high boost. They blew an engine. The RB duct pulls a little more air from the stock opening. This means that even more warm air will be pulled back thru the intercooler.

I don't feel it is a very good product.

 

Hah, I'm using the PFS intake which sucks even MORE air back through the intercooler!

Actually, I'm getting the PFC very soon and I'll see what my intake air temps are....perhaps a change in the intake system will be required, but maybe not.

 

With enough boost sucking warm air thru the intercooler, perhaps we should rename it. The "interwarmer".

We could use it to heat the car, and save weight by removing the heater elements!!

Anyone have Mazda's e-mail address.

 

Only pulls warm air through at very low speed and high rpm...

 

Actually it reverse sucks the intercooler (lol). It only gets warm/hot air at idle speed and in between shifts which is why they made a seperate chamber for the intake and SMIC on 99+ models and that's what the hole where the front license plate is for.

Yes the RB duct It improves the orginal design but the material out of dried leaves (paper thin plastic) which will deteriarate and crumble with heat and time. I have one that is crumbled. I am not knocking the design, that's good but the material is not worth more then $20 retail.

I have not purchased Adam C's kit but if I didn't throw away my stock box I would have. I have seen it in person and it will do a similar job as the M2 and other CAI boxes and is less money then the RB duct.

 

Buy a cold airintake and save your money.
